git - 无法通过 'docker attach'到达Bash Shell

Question

在远程服务器上，docker正在基于nginx和Dockerfile运行镜像

FROM nginx

COPY ./ /usr/share/nginx/html
EXPOSE 80
CMD /usr/sbin/nginx -g "daemon off;"

docker ps显示:

CONTAINER ID        IMAGE                              COMMAND                CREATED             STATUS              PORTS                         NAMES
a71e45d5cd40        myUsername/myNginxWebsite:latest   "\"/bin/sh -c '/usr/   23 hours ago        Up 23 hours         80/tcp, 443/tcp               sharp_fermi       

通过SSH连接到远程服务器后，运行docker attach <container_id>将显示nginx的输出，然后按ctrl + q，ctrl + c，ctrl + p不会使我回到bash shell。

是否有可能进入 shell ？我想做类似git pull的事情。

Answer 1

docker exec -it <container-id-or-name> /bin/bash
根据https://docs.docker.com/reference/commandline/cli/#exec-

Usage: docker exec [OPTIONS] CONTAINER COMMAND [ARG...]

Run a command in a running container

-d, --detach=false Detached mode: run command in the background -i, --interactive=false Keep STDIN open even if not attached -t, --tty=false Allocate a pseudo-TTY
