Getting error when building custom image with 'ansible' pack added.

• I'm trying to build custom pack image with 'ansible' pack added. But keep getting this error message:

• After some diggin' around, i've found this issue and begin to suspect that there was some missing dependencies here. I was right, libkrb5-dev gcc python3-dev python-dev were missing.
• I did some simple, temporary workaround for this. What i did was add those missing dependencies directly into the builder Dockerfile using sed.
  sed -i "2i RUN apt update && apt install -y libkrb5-dev gcc python3-dev python-dev && rm -rf /var/lib/apt/lists/*" ./st2packs-image/Dockerfile
• And then proceed to build the image as the docs says. Summary for everything i've did:

$ git clone git@github.com:stackstorm/st2packs-dockerfiles
$ cd st2packs-dockerfiles
$ sed -i "2i RUN apt update && apt install -y libkrb5-dev gcc python3-dev python-dev && rm -rf /var/lib/apt/lists/*" ./st2packs-image/Dockerfile
$ docker build --build-arg PACKS="ansible" -t ${DOCKER_REGISTRY}/st2packs:<version_number> st2packs-image

• I hope this could help and if anyone has better idea/way feel free to add. I'd really appreciate it.

@FreddyAprilliant Thanks for sharing! 👍

I'd recommend considering the Dockerfile for building your packs as an infrastructure-as-code artifact, keep it in the repo so you can just do default docker build anytime without specifying the CLI parameters:

Dockerfile:

# list of packs to be installed
ARG PACKS="ansible"

FROM stackstorm/st2packs:builder AS builder
# custom dependencies
RUN apt update && apt install -y libkrb5-dev gcc python3-dev python-dev

RUN /opt/stackstorm/st2/bin/st2-pack-install ${PACKS}
FROM stackstorm/st2packs:runtime

that'll technically do the same. Choose the approach suitable for situation.
