micromamba fails to activate env inside apptainer

[kpetrov]

Hello,

I am trying to run micromamba inside a container (v2.0.2). Standard procedure works well outside the container on my RHEL 8.6.

complete -o default -F _umamba_bash_completions micromamba
fi

• basename /usr/local/bin/micromamba
• __exe_name=micromamba
• __exe_name=micromamba
• [[ micromamba == micromamba ]]
  /.post.script: 55: eval: [[: not found
• [[ micromamba == mamba ]]
  /.post.script: 57: eval: [[: not found
• echo Error unknow MAMBA_EXE: "/usr/local/bin/micromamba", filename must be mamba or micromamba
  Error unknow MAMBA_EXE: "/usr/local/bin/micromamba", filename must be mamba or micromamba
• [ -z ]
• export CONDA_SHLVL=0
• export PATH=/opt/micromamba/condabin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
• [ -z x ]
  /.post.script: 88: eval: Syntax error: "(" unexpected (expecting "}")
  FATAL: While performing build: while running engine: while running %post section: exit status 2

this is my apptainer code (based off ubuntu 22.04):

export MAMBA_ROOT_PREFIX=/opt/micromamba
curl -Ls https://micro.mamba.pm/api/micromamba/linux-64/latest | tar -xvj -C /usr/local/bin --strip-components=1 bin/micromamba
eval "$(micromamba shell hook -s bash)"
# Create base environment
micromamba create -n base -c conda-forge python=3.11
# Activate
micromamba activate

Am I doing it wrong it is it an actual problem?

thanks in advance!

k.
