问题描述
所以我刚刚在Mac上更新了Docker，并且适应Docker似乎是充满挑战和困惑的.
So I just updated Docker on my Mac and getting adjusted to Docker seems to be quite challenging and confusing.
几周前，我可以通过运行以下命令(这是我的命令行历史记录)来介意docker容器上的端口8834到本地主机上的端口8834:
A few weeks ago, I was able to mind port 8834 on the docker container to port 8834 on my local host by running the following commands (this is my command line history):
8450 docker attach -p 8834:8834 compassionate_chandrasekhar
8452 docker start -p 8834:8834 compassionate_chandrasekhar
今天，如果我尝试做同样的事情，则会发生以下情况:
Today, if I try to do the same thing, the following happens:
[user:test.local:]$ docker container ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
225146ec71d6 myuser/kali:kali "/usr/bin/zsh" 9 minutes ago Exited (0) 2 minutes ago agitated_fermat
e4389cac288a myuser/kali:kali "/usr/bin/zsh" 2 weeks ago Exited (255) 2 weeks ago suspicious_hypatia
265f2c9215c5 myuser/kali:kali "/usr/bin/zsh" 2 weeks ago Exited (0) 2 weeks ago hungry_poincare
34b36b4d8a7e myuser/kali:kali "/usr/bin/zsh" 2 weeks ago Created amazing_stonebraker
其次:
[user:test.local:]$ docker start -p 8834:8834 agitated_fermat
unknown shorthand flag: 'p' in -p
See 'docker start --help'.
我做错了什么?极为混乱
What am I doing wrong? Extremely confusing
推荐答案
只能使用新创建的容器而不是现有容器来完成发布端口.因此，您需要停止容器并使用所需的端口创建一个新容器
Publishing ports can be done only with newly created containers not existing containers. So you need to stop the container and create a new one with the port you need
