linux - Docker容器有一些奇怪的地址，03a0646cb148:8888/任何人都可以解释这种地址的类型吗？

Question

我正在运行一个有两个不同地址的容器，我了解http://127.0.0.1:8888/?token=..。和:: 1分别指的是ipv4和6中的本地主机，但是此http:// 03a0646cb148:8888 /？token = ...地址来自哪里？

lib@DESKTOP-ISQPMPU:~$ docker run --rm  -p 8888:8888  -v $PWD:/home/jovyan/pwd  --env JUPYTER_ENABLE_LAB=yes  --env JUPYTER_TOKEN=x --name ihaskell_notebook crosscompass/ihaskell-notebook:latest

Answer 1

where does this http://03a0646cb148:8888/?token=... address comes from ?

那是一个容器的主机名。 docker使用的Linux命名空间之一是UTS，它最容易被认为是主机名。容器中的主机名默认为短容器ID:

$ docker run -it --name test-host busybox hostname
e93c238e1aa3                  

$ docker container ls -l
CONTAINER ID    IMAGE      COMMAND      CREATED             STATUS                          PORTS    NAMES
e93c238e1aa3    busybox    "hostname"   About a minute ago  Exited (0) About a minute ago            test-host

$ docker container inspect test-host --format '{{.ID}}'
