如何从主机获取 Docker 容器的 IP 地址

Question

Is there a command I can run to get the container's IP address right from the host after a new container is created?

Basically, once Docker creates the container, I want to roll my own code deployment and container configuration scripts.

Answer 1

The --format option of inspect comes to the rescue.

Modern Docker client syntax is:

docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id

Old Docker client syntax is:

docker inspect --format '{{ .NetworkSettings.IPAddress }}' container_name_or_id

These commands will return the Docker container's IP address.

As mentioned in the comments: if you are on Windows, use double quotes " instead of single quotes ' around the curly braces.

Answer 2

You can use docker inspect <container id> .

For example:

CID=$(docker run -d -p 4321 base nc -lk 4321);
docker inspect $CID

Answer 3

First get the container ID:

docker ps

(First column is for container ID)

Use the container ID to run:

docker inspect <container ID>

At the bottom,under "NetworkSettings", you can find "IPAddress"

Or Just do:

docker inspect <container id> | grep "IPAddress"

Answer 4

docker inspect CONTAINER_ID | grep "IPAddress"

您可以将-i添加到 grep 以忽略大小写，那么即使以下内容也可以工作：

docker inspect CONTAINER_ID | grep -i "IPaDDreSS"

Answer 5

To get all container names and their IP addresses in just one single command.

docker inspect -f '{{.Name}} - {{.NetworkSettings.IPAddress }}' $(docker ps -aq)

If you are using docker-compose the command will be this:

docker inspect -f '{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq)

The output will be:

/containerA - 172.17.0.4
/containerB - 172.17.0.3
/containerC - 172.17.0.2

Answer 6

Add this shell script in your ~/.bashrc or relevant file:

docker-ip() {
  docker inspect --format '{{ .NetworkSettings.IPAddress }}' "$@"
}

Then, to get an IP address of a container, simply do this:

docker-ip YOUR_CONTAINER_ID

For the new version of the Docker, please use the following:

docker-ip() {
        docker inspect --format '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' "$@"
}

Answer 7

In Docker 1.3+, you can also check it using:

Enter the running Docker (Linux):

docker exec [container-id or container-name] cat /etc/hosts
172.17.0.26 d8bc98fa4088
127.0.0.1   localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.17 mysql

For windows:

docker exec [container-id or container-name] ipconfig

Answer 8

显示所有容器的 IP 地址：

docker inspect --format='{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq)

Answer 9

As of Docker version 1.10.3, build 20f81dd

Unless you told Docker otherwise, Docker always launches your containers in the bridge network. So you can try this command below:

docker network inspect bridge

Which should then return a Containers section which will display the IP address for that running container.

[
    {
        "Name": "bridge",
        "Id": "40561e7d29a08b2eb81fe7b02736f44da6c0daae54ca3486f75bfa81c83507a0",
        "Scope": "local",
        "Driver": "bridge",
        "IPAM": {
            "Driver": "default",
            "Options": null,
            "Config": [
                {
                    "Subnet": "172.17.0.0/16"
                }
            ]
        },
        "Containers": {
            "025d191991083e21761eb5a56729f61d7c5612a520269e548d0136e084ecd32a": {
                "Name": "drunk_leavitt",
                "EndpointID": "9f6f630a1743bd9184f30b37795590f13d87299fe39c8969294c8a353a8c97b3",
                "IPv4Address": "172.17.0.2/16",
                "IPv6Address": ""
            }
        },
        "Options": {
            "com.docker.network.bridge.default_bridge": "true",
            "com.docker.network.bridge.enable_icc": "true",
            "com.docker.network.bridge.enable_ip_masquerade": "true",
            "com.docker.network.bridge.host_binding_ipv4": "0.0.0.0",
            "com.docker.network.bridge.name": "docker0",
            "com.docker.network.driver.mtu": "1500"
        }
    }
]

Answer 10

Execute:

docker ps -a

This will display active docker images:

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                       PORTS               NAMES
3b733ae18c1c        parzee/database     "/usr/lib/postgresql/"   6 minutes ago       Up 6 minutes                 5432/tcp            serene_babbage

Use the CONTAINER ID value:

docker inspect <CONTAINER ID> | grep -w "IPAddress" | awk '{ print $2 }' | head -n 1 | cut -d "," -f1

"172.17.0.2"

Answer 11

Based on some of the answers I loved, I decided to merge them to a function to get all the IP addresses and another for an specific container. They are now in my .bashrc file.

docker-ips() {
    docker inspect --format='{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq)
}

docker-ip() {
  docker inspect --format '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' "$@"
}

The first command gives the IP address of all the containers and the second a specific container's IP address.

docker-ips
docker-ip YOUR_CONTAINER_ID

Answer 12

Here's a quick working answer:

Get your container name or ID:

docker container ls

Then get the IP:

docker inspect <container_ID Or container_name> |grep 'IPAddress'

Get the port:

docker inspect <container_ID Or container_name> |grep 'Port'

Answer 13

My answer:

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}} %tab% {{.Name}}' $(docker ps -aq
) | sed 's#%tab%#\t#g' | sed 's#/##g' | sort -t . -k 1,1n -k 2,2n -k 3,3n -k 4,4n

Also as a bash alias:

docker-ips() {   docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}} %tab% {{.Name}}' $(docker ps -aq) | sed 's#%tab%#\t#g' | sed 's#/##g' | sort -t . -k 1,1n -k 2,2n -k 3,3n -k 4,4n }

Output is sorted by IP address, and tab delimited:

# docker-ips
172.18.0.2       memcached
172.18.0.3       nginx
172.18.0.4       fpm-backup
172.18.0.5       dns
172.18.0.6       fpm-beta
172.18.0.7       exim
172.18.0.8       fpm-delta
172.18.0.9       mariadb
172.18.0.10      fpm-alpha
172.19.0.2       nextcloud-redis
172.19.0.3       nextcloud-db
172.19.0.4       nextcloud

Answer 14

I wrote the following Bash script to get a table of IP addresses from all containers running under docker-compose .

function docker_container_names() {
    docker ps -a --format "{{.Names}}" | xargs
}

# Get the IP address of a particular container
dip() {
    local network
    network='YOUR-NETWORK-HERE'
    docker inspect --format "{{ .NetworkSettings.Networks.$network.IPAddress }}" "$@"
}

dipall() {
    for container_name in $(docker_container_names);
    do
        local container_ip=$(dip $container_name)
        if [[ -n "$container_ip" ]]; then
            echo $(dip $container_name) " $container_name"
        fi
    done | sort -t . -k 3,3n -k 4,4n
}

You should change the variable network to your own network name.

Answer 15

Docker is written in Go and it uses Go syntax for query purposes too.

To inspect the IP address of a particular container, you need to run the command ( -f for "format"):

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_id_or_name

For the container ID or name, you can run the command

docker container ls

which will list every running container.

Answer 16

Reference containers by name:

docker run ... --name pg-master

Then grab the IP address address by name:

MASTER_HOST=$(docker inspect --format '{{ .NetworkSettings.IPAddress }}' pg-master)

Answer 17

Here's is a solution that I developed today in Python, using the docker inspect container JSON output as the data source.

I have a lot of containers and infrastructures that I have to inspect, and I need to obtain basic network information from any container, in a fast and pretty manner. That's why I made this script.

IMPORTANT: Since the version 1.9, Docker allows you to create multiple networks and attach them to the containers.

#!/usr/bin/python

import json
import subprocess
import sys

try:
    CONTAINER = sys.argv[1]
except Exception as e:
    print "\n\tSpecify the container name, please."
    print "\t\tEx.:  script.py my_container\n"
    sys.exit(1)

# Inspecting container via Subprocess
proc = subprocess.Popen(["docker","inspect",CONTAINER],
                      stdout=subprocess.PIPE,
                      stderr=subprocess.STDOUT)

out = proc.stdout.read()
json_data = json.loads(out)[0]

net_dict = {}
for network in json_data["NetworkSettings"]["Networks"].keys():
    net_dict['mac_addr']  = json_data["NetworkSettings"]["Networks"][network]["MacAddress"]
    net_dict['ipv4_addr'] = json_data["NetworkSettings"]["Networks"][network]["IPAddress"]
    net_dict['ipv4_net']  = json_data["NetworkSettings"]["Networks"][network]["IPPrefixLen"]
    net_dict['ipv4_gtw']  = json_data["NetworkSettings"]["Networks"][network]["Gateway"]
    net_dict['ipv6_addr'] = json_data["NetworkSettings"]["Networks"][network]["GlobalIPv6Address"]
    net_dict['ipv6_net']  = json_data["NetworkSettings"]["Networks"][network]["GlobalIPv6PrefixLen"]
    net_dict['ipv6_gtw']  = json_data["NetworkSettings"]["Networks"][network]["IPv6Gateway"]
    for item in net_dict:
        if net_dict[item] == "" or net_dict[item] == 0:
            net_dict[item] = "null"
    print "\n[%s]" % network
    print "\n{}{:>13} {:>14}".format(net_dict['mac_addr'],"IP/NETWORK","GATEWAY")
    print "--------------------------------------------"
    print "IPv4 settings:{:>16}/{:<5}  {}".format(net_dict['ipv4_addr'],net_dict['ipv4_net'],net_dict['ipv4_gtw'])
    print "IPv6 settings:{:>16}/{:<5}  {}".format(net_dict['ipv6_addr'],net_dict['ipv6_net'],net_dict['ipv6_gtw'])

The output is:

$ python docker_netinfo.py debian1

[frontend]

02:42:ac:12:00:02   IP/NETWORK        GATEWAY
--------------------------------------------
IPv4 settings:      172.18.0.2/16     172.18.0.1
IPv6 settings:            null/null   null

[backend]

02:42:ac:13:00:02   IP/NETWORK        GATEWAY
--------------------------------------------
IPv4 settings:      172.19.0.2/16     172.19.0.1
IPv6 settings:            null/null   null

Answer 18

I use this simple way

docker exec -it <container id or name> hostname -i

eg

ubuntu@myhost:~$ docker exec -it 3d618ac670fe hostname -i
10.0.1.5

Answer 19

为了扩展 ko-dos 的回答，这是一个列出所有容器名称及其 IP 地址的别名：

alias docker-ips='docker ps | tail -n +2 | while read -a a; do name=${a[$((${#a[@]}-1))]}; echo -ne "$name\t"; docker inspect $name | grep IPAddress | cut -d \" -f 4; done'

Answer 20

NOTE!!! for Docker Compose Usage:

Since Docker Compose creates an isolated network for each cluster, the methods below do not work with docker-compose .

---

The most elegant and easy way is defining a shell function, currently the most-voted answer @WouterD's :

dockip() {
  docker inspect --format '{{ .NetworkSettings.IPAddress }}' "$@"
}

Docker can write container IDs to a file like Linux programs:

Running with --cidfile=filename , Docker dumps the ID of the container to "filename".

See " Docker runs PID equivalent Section " for more information.

--cidfile="app.cid": Write the container ID to the file

Using a PID file:

1. Running container with --cidfile parameter, the app.cid file content is like:

    a29ac3b9f8aebf66a1ba5989186bd620ea66f1740e9fe6524351e7ace139b909

2. You can use file content to inspect Docker containers:

    blog-v4 git:(develop) ✗ docker inspect `cat app.cid`

3. You can extract the container IP using an inline Python script:

    $ docker inspect `cat app.cid` | python -c "import json;import sys;\\ sys.stdout.write(json.load(sys.stdin)[0]['NetworkSettings']['IPAddress'])" 172.17.0.2

Here's a more human friendly form:

#!/usr/bin/env python
# Coding: utf-8
# Save this file like get-docker-ip.py in a folder that in $PATH
# Run it with
# $ docker inspect <CONTAINER ID> | get-docker-ip.py

import json
import sys

sys.stdout.write(json.load(sys.stdin)[0]['NetworkSettings']['IPAddress'])

See " 10 alternatives of getting the Docker container IP addresses " for more information.

Answer 21

docker inspect --format '{{ .NetworkSettings.IPAddress }}' <containername or containerID here>

The above works if the container is deployed to the default bridge network.

However, if using a custom bridge network or a overlay network, I found the below to work better:

docker exec <containername or containerID here> /sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'

Answer 22

将之前的答案与根据 Docker 映像名称查找容器 ID 相结合：

docker inspect --format '{{ .NetworkSettings.IPAddress }}' `docker ps | grep $IMAGE_NAME | sed 's/\|/ /' | awk '{print $1}'`

Answer 23

Just for completeness:

I really like the --format option, but at first I wasn't aware of it so I used a simple Python one-liner to get the same result:

docker inspect <CONTAINER> |python -c 'import json,sys;obj=json.load(sys.stdin);print obj[0]["NetworkSettings"]["IPAddress"]'

Answer 24

If you installed Docker using Docker Toolbox, you can use the Kitematic application to get the container IP address:

1. Select the container
2. Click on Settings
3. Click in Ports tab.

Answer 25

To get the IP address and host port of a container:

docker inspect containerId | awk '/IPAddress/ || /HostPort/'

Output:

    "HostPort": "4200"
                    "HostPort": "4200"
        "SecondaryIPAddresses": null,
        "IPAddress": "172.17.0.2",
                "IPAddress": "172.17.0.2",

Answer 26

For those who came from Google to find a solution for command execution from the terminal (not by a script), " jid ", which is an interactive JSON drill-down utility with autocomplete and suggestion, lets you do the same thing with less typing.

docker inspect $CID | jid

Type Tab .Net Tab and you'll see something like:

[Filter]> .[0].NetworkSettings
{
  "Bridge": "",
  "EndpointID": "b69eb8bd4f11d8b172c82f21ab2e501fe532e4997fc007ed1a997750396355d5",

"172.17.0.2"

Answer 27

对于 Windows 10：

docker inspect --format "{{ .NetworkSettings.IPAddress }}"  containerId

Answer 28

这将列出主机上的所有容器 IP：

sudo docker ps -aq | while read line;  do sudo docker inspect -f '{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $line ; done

Answer 29

The accepted answer does not work well with multiple networks per container:

> docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' cc54d96d63ea

172.20.0.4172.18.0.5

The next best answer is closer:

> docker inspect cc54d96d63ea | grep "IPAddress"

"SecondaryIPAddresses": null,
"IPAddress": "",
    "IPAddress": "172.20.0.4",
    "IPAddress": "172.18.0.5",

I like to use jq to parse the network JSON:

> docker inspect cc54d96d63ea | jq -r 'map(.NetworkSettings.Networks) []'

{

    "IPAMConfig": null,
    "Links": [

      "web"
    ],
    "NetworkID": "7779959d7383e9cef09c970c38c24a1a6ff44695178d314e3cb646bfa30d9935",

}

To list the IP addresses of every container then becomes:

for s in `docker ps -q`; do
  echo `docker inspect -f "{{.Name}}" ${s}`:
  docker inspect ${s} | jq -r 'map(.NetworkSettings.Networks) []' | grep "IPAddress";
done

/server1_web_1:

    "IPAddress": "172.18.0.3",
/nginx-proxy:
    "IPAddress": "172.20.0.2",
    "IPAddress": "172.18.0.2",

Answer 30

Docker检查用于打印所有容器ips及其各自的名称

docker ps -q | xargs -n 1 docker inspect --format '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}} {{ .Name }}' | sed 's/ \// /'

Answer 31

Is there a command I can run to get the container's IP address right from the host after a new container is created?

Basically, once Docker creates the container, I want to roll my own code deployment and container configuration scripts.

Answer 32

For Windows containers use

docker exec <container> ipconfig

where <container> is the name or the id of the container.

You can use docker ps to find the id of the container.

Answer 33

If you forgot container ID or don't want to manipulate with shell commands, it's better to use UI like Portainer.

https://portainer.io/

$ docker volume create portainer_data
$ docker run -d -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer

There you can find all information about container also IP.

Answer 34

Nobody has proposed the Docker Python API yet. Docker API solution to get IP Address is fairly simple.

*NIX based OS: docker api 3.7 (updated thanks to canadadry from the comments)

import docker

client = docker.DockerClient(base_url='unix://var/run/docker.sock')
x_container = client.containers(filters={"name":"x_container"})[0]
x_ip_addr = x_container["NetworkSettings"]["Networks"]["NETWORK_NAME"]["IPAddress"]

OS Agnostic: docker api 4.0.x (added thanks to pds from the comments)

import docker

client = docker.from_env()
container = client.containers.get(container_name)
vars( container )["attrs"]["NetworkSettings"]["Networks"]["<NETWORK_NAME>"]["IPAddress"]

Wasn't too hard to find, but is useful. additionally this can be easily modified to find all IP's assigned to a container on various networks.

Answer 35

Inspect didn't work for me. Maybe as I was using -net host and some namespaces.

Anyway, I found this to work nicely:

docker exec -i -t NAME /sbin/ifconfig docker0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'

Answer 36

I had to extract docker container IP Adress by docker container name for further usage in deployment scripts. For this purpose I have written the following bash command:

docker inspect $(sudo docker ps | grep my_container_name | head -c 12) | grep -e \"IPAddress\"\:[[:space:]]\"[0-2] | grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}'

Answer 37

docker inspect <container id> | grep -i ip

例如：

docker inspect 2b0c4b617a8c | grep -i ip

Answer 38

This script will get the IPv4 address for all running containers without further processing or interpreting results. If you don't want the container name as well, you can just remove the "echo -n $NAME:" line. Great for automation or filling variables.

#!/bin/sh
for NAME in $(docker ps --format {{.Names}})
do
  echo -n "$NAME:"
  docker inspect $NAME | grep -i "ip.*[12]*\.[0-9]*" | \
         sed -e 's/^  *//g' -e 's/[",]//g' -e 's/[a-zA-Z: ]//g'
done

you can just create an alias too if you wanted like this:

在 Windows PowerShell 中尝试：

     docker inspect -f "{{ .NetworkSettings.Networks.nat.IPAddress }}" <container id>

Answer 41

The accepted answer covers exactly what to type fairly well, but here's a minor improvement:

docker container inspect \
  --format '{{range .NetworkSettings.Networks}}{{.IPAddress}} {{end}}' \
  $container_id_or_name

This uses the docker container inspect instead of the more generic docker inspect since docker is moving to a noun+verb syntax in their commands, and removing ambiguity of what you are inspecting. I've also included a space after the IP address since containers can be on more than one docker network with more than one IP address. That could be swapped out for any other character or string that makes sense to you.

---

For those that want to know how they can lookup other values, I often use the following to output any docker formatted syntax into json:

docker container inspect --format '{{json .}}' $container_id_or_name | jq .

You may need to install jq for this to work, or you can leave off the trailing command to read the json as a single long line. When viewing this output, you can see each key name and it's parents so you can create your own format strings to output anything you want. The format syntax is implemented with golang's template with some extra docker specific functions included .

Basically, once Docker creates the container, I want to roll my own code deployment and container configuration scripts.

The main reason for my answer is this comment has a huge red flag to me. It indicates that your images do not contain everything needed to run your application, a big anti-pattern when working with containers. With a dozen clients over many years, I've yet to find a real world use case to connect directly to a container by it's internal IP address from the docker host that didn't have a better option. Instead, if there's post-startup configuration in your container that needs to run, this is often done with an entrypoint script.

There is also a red flag that you are bypassing docker's networking model. With docker networking, there are two options. First, when communicating between containers, this is done with a user created network and using docker's built-in DNS to connect to the container by name or network alias rather than by an IP address that would change when the container is recreated. And for communicating from outside of docker to the container, this is done by publishing a port from the docker host to the container, and then connecting to the host on that port rather than to the container directly. If you stick with these two options, you should be able to access your application without ever knowing its internal IP address.

Answer 42

Along with the accepted answer if you need a specific handy alias to get a specific container ip use this alias

alias dockerip='f(){ docker inspect $1|grep -i "ipaddress.*[12]*\.[0-9]*"|sed -e "s/^  *//g" -e "s/[\",]//g" -e "s/[*,]//g" -e "s/[a-zA-Z: ]//g" | sort --unique;  unset -f f; }; f'

and then you can get your container ip with

dockerip <containername>  

You can also use containerid instead of containername

BTW accepted great answer doenst produce a clean output so I edited it and using like this ;

alias dockerips='for NAME in $(docker ps --format {{.Names}}); do echo -n "$NAME:"; docker inspect $NAME|grep -i "ipaddress.*[12]*\.[0-9]*"|sed -e "s/^  *//g" -e "s/[\",]//g" -e "s/[_=*,]//g" -e "s/[a-zA-Z: ]//g "| sort --unique;done'

If you want to quickly see all Docker IP addresses, or without typing the instance name, you can hack the docker ps<\/code> command adding this to your ~\/.bashrc<\/code> file:

function docker-ips() {
    docker ps | while read line; do
        if `echo $line | grep -q 'CONTAINER ID'`; then
            echo -e "IP ADDRESS\t$line"
        else
            CID=$(echo $line | awk '{print $1}');
            IP=$(docker inspect -f "{{ .NetworkSettings.IPAddress }}" $CID);
            printf "${IP}\t${line}\n"
        fi
    done;
}

There are various ways to get the IP of the container from the host

Answer 51

Linux Container<\/strong>

Answer 52

Extract IP Using Arbitrary String:

Many- nearly all - the solutions I've read in this question require the intermediate step of the user first identifying the <container name> or <container ID> first and then supplying this to their solution to reveal the IP.

IPs can change when containers are recreated, and if this happens, any script referencing it will now be broken....

So I needed a way of extracting the IP of a container WITHOUT MANUAL INTERVENTION that ensured a script ALWAYS had the correct IP even if it changed every time container was recreated.

Solution:

#!/bin/bash

# Only need to set "CONTAINERNAME" variable with an arbitrary
# string found in either the Container ID or Image Name and
# it prints container IP. Ensure the string is unique to desired host

CONTAINERNAME='mariadb-blog'
CONTAINERID="$(docker ps | grep -i $CONTAINERNAME | awk '{print $1}')"
CONTAINERIP="$(docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $CONTAINERID)"

echo "$CONTAINERIP"

Conclusion:

I've tested this script with my own Linux Docker-Compose hosts and it works reliably as of 20220722. Indeed, it's easy to copy-n-paste the script to validate my results are reproducible.

PLEASE NOTE : There is a potential reliability achilles heal: if you don't cut your own docker images and rely on a third party's, they could change their naming convention of the image and break the grep in the script. Therefore I'd suggest setting the arbitrary string to the Container Name because YOU can control this, ensuring the grep for the string always succeeds and prints the IP to supply to your script.

Answer 53

Best way that no one mention is to assign a hostname to the container.

docker run -d --hostname localcontainerhostname imageName

This will give you the ip address, but you probably want to use the hostname anyway

nslookup localcontainerhostname

Answer 54

If you're on Windows, you may not get any information from docker inspect , in which case your best bet is to actually use ipconfig /all and look for the Ethe.net adapter vEthe.net (WSL): section where you can see an IPv4 address. . . : xxx.xxx.xxx.xxx (preferred) - this will be the IP you can use in the url on your local browser.
