如何从 Windows 主机获取位于桥接网络内的 Docker 容器的 IP 地址？

Question

A bridge network has been created in docker using the following:

docker network create blognetwork

And a container has been created in that network with the following:

docker run --name=blogdb --network=blognetwork -p 3306:3306 -e --bind-address=0.0.0.0 -e=MYSQL_ROOT_PASSWORD=mypassword -detach mysql

How do I access the ip address of the new container, within the "blognetwork", from a windows host?

How do I get the ip address of the form XXXX, on its own? I know I can use the following to get a large json output with this data in it:

docker network inspect blognetwork

Answer 1

You can get directly the ip by using docker inspect and a proper format:

docker inspect containerId --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}'

More info in the Docker documentation.

Answer 2

You can get directly the IP address by using docker inspect. Docker inspect provides detailed information on constructs controlled by Docker.

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.

If you are on Windows, use double quotes " instead of single quotes ' around the curly braces.

Answer 3

这是获取容器信息和容器 IP 的命令。

docker inspect 'ContainerID'

Answer 4

Since you ran

docker run -p 3306:3306 ...

you should access the service via port 3306 using your host's DNS name or IP address.

In the very specific case where you're at a shell prompt or browser URL entry on the machine where you ran docker run , assuming you're not using Docker Machine or Docker Toolbox, in this case and in this case only, you can use localhost:3306 to access the container. Never ever use localhost for anything else around Docker unless you're totally clear what it means. (If you ever start writing a question that uses the words "...the localhost of..." then localhost isn't what you want.)

If you are trying to reach this container from another container, since you ran

docker run --name=blogdb --network=blognetwork ...

you can use the name blogdb as a host name, and Docker provides an internal DNS service that can resolve it to something that will reach the container.

You never want the Docker-internal IP address, and should never run docker inspect to try to find it. The two biggest problems with it are that it's unreachable from off-host and that it changes when the container is deleted and recreated.
