Docker bash提示不显示颜色输出 [英] Docker bash prompt does not display color output

问题描述

我使用命令:docker run --rm -it govim bash -l运行docker镜像，但是 它不显示颜色输出.如果我source ~/.bash_profile或再次运行bash -l，则输出将正确以彩色输出.

I use command: docker run --rm -it govim bash -l to run docker images but it does not display color output. If I source ~/.bash_profile or run bash -l again, output will then correctly be output with color.

我的bash_profile和bash_prompt

推荐答案

OP SolomonT 报告 docker run 与

The OP SolomonT reports that docker run with env do work:

docker run --rm -it -e "TERM=xterm-256color" govim bash -l

And Fernando Correia adds in the comments:

为了同时获得颜色支持和使tmux正常工作，我结合了两个示例:

To get both color support and make tmux work, I combined both examples:

docker exec -it my-container env TERM=xterm-256color script -q -c "/bin/bash" /dev/null

如 chepner 所述(较早的回答)，由于 bash_prompt 是

---

As chepner commented (earlier answer), .bash_profile is sourced (itis an interactive shell), since bash_prompt is called by .bash_profile.

但是 docker问题9299 说明了TERM似乎没有设置立即，迫使用户使用以下命令打开另一个bash:

But docker issue 9299 illustrates that TERM doesn't seem to be set right away, forcing the users to open another bash with:

docker exec -ti test env TERM=xterm-256color bash -l

您在问题8755 中也遇到了类似的颜色问题.

You have similar color issues with issue 8755.

说明/重现问题:

docker exec -ti $CONTAINER_NAME tty
not a tty

当前解决方法是:

docker exec -ti `your_container_id` script -q -c "/bin/bash" /dev/null

两者都假设您首先有一个正在运行的容器，这在这里可能不方便.

Both are supposing you have a running container first, which might not be convenient here.
