如何将 Docker 容器暴露给 Web

Question

I am new to the fabulous world of docker and star twith asking a quite noobish question I think. But first, a little information about myself:

I am working with exist-db and plan to move it to docker. So set it up on the server, I thought and followed this instructions. I am not importing my app, yet, as I want to familiarize with how it works, before I move towards “the cloud”.

I am running docker on a server, which I access using Putty. I have set it up properly, even my existdb container works:

curl localhost:8080

gives me the html-output I am expecting from existDB. However, when I attempt to [server-IP]:8080 in firefox, I cannot access it.

I know I haven't configured anything else yet, besides when I started the container, but the following.

docker run -it -d -p 8080:8080 -p 8443:8443 --name exist existdb/existdb:latest

Shouldn't this bind my container[8080] to my host[8080] (or 8443 for that matter), so that I should in theory be able to [Host-ip]:8080 and see the exist Interface?

I do not want to use host-mode, as I'll probably have several apps up& running in the future, so that I think it better to separate the interfaces.

Answer 1

Following this answer here and I quote

By default, Docker exposes container ports to the IP address 0.0.0.0 (this matches any IP on the system). If you prefer, you can tell Docker which IP to bind on. To bind on IP address 10.0.0.3, host port 80, and container port 8080:

docker run -p 10.0.0.3:80:8080 <your image>

following the comments i have tried to regenrate the setuation and as you can see

CONTAINER ID        IMAGE                    COMMAND                  CREATED             STATUS                   PORTS                                            NAMES
9eebf8c6f3b2        existdb/existdb:latest   "java org.exist.star…"   2 minutes ago       Up 2 minutes (healthy)   0.0.0.0:8080->8080/tcp, 0.0.0.0:8443->8443/tcp   exist

so you need to run the command like the following docker run -it -d -p 0.0.0.0:8080:8080 -p 0.0.0.0:8443:8443 --name exist existdb/existdb:lates
