[choovick]

Current behavior

Getting spaceship_exec_vcs_info_precmd_hook:2: vcs_info: function definition file not found error when installing spaceship prompt in alpine container.

Used to work before...

_Dockerfile_

FROM alpine

# adding required packages
RUN apk add --no-cache git bash zsh

# Zsh config
RUN git clone git://github.com/robbyrussell/oh-my-zsh.git ~/.oh-my-zsh && \
  cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc

# Spaceship prompt setup https://github.com/denysdovhan/spaceship-prompt#oh-my-zsh
RUN ZSH_CUSTOM="/root/.oh-my-zsh/custom" && \
 git clone git://github.com/denysdovhan/spaceship-prompt.git "$ZSH_CUSTOM/themes/spaceship-prompt" && \
 ln -s "$ZSH_CUSTOM/themes/spaceship-prompt/spaceship.zsh-theme" "$ZSH_CUSTOM/themes/spaceship.zsh-theme"
# change theme to spaceship
RUN sed -i -E 's/ZSH_THEME="(.*?)"/ZSH_THEME="spaceship"/' ~/.zshrc

# setting work dir to root home folder
WORKDIR /root

_Steps to reproduce:_

1. Create above Dockerfile

2. Build docker file
   docker build -t zsh .

3. Run container:
   docker run --rm -it zsh /bin/zsh

4. Error should be displayed and will be displayed on subsequent command

➜ docker run --rm -it zsh /bin/zsh
spaceship_exec_vcs_info_precmd_hook:2: vcs_info: function definition file not found

root in ~

Expected behavior

Error should now be generated

Am I missing any install steps or components?

Thank you @choovick for the detailed issue filing, Spot on for reproducing the issue :smile:

We depend on vcs_info module for git section. Seems like vcs_info is packaged separately on alpine. apk add zsh-vcs loads the required module.

@salmanulfarzy you sir amazing! that did it! lightweight alpine packages... :)

added zsh-vcs package to my docker file.
