Docker build instructions do not work

[prestonvanloon]

Followed instructions here https://github.com/linkedin/iris/tree/master/ops/packer

packer build -only=docker ./output/iris.json

<lots of logs>

I have different problem during building of docker image using Packer:

    docker: Processing /home/iris/source

Steps to reproduce:

git clone https://github.com/linkedin/iris.git 
cd iris/ops/packer
mkdir output
python3 gen_packer_cfg.py ./iris.yaml | tail -n +2 > ./output/iris.json
packer build -only=docker ./output/iris.json

I was able to fix problem above by hard coding long_description. Also I had to downgrade setuptools to 44.1.1.

In my case image is built but container fails with /bin/sh: 0: Can't open sudo. However, I can log into, run sudo -EHu iris bash -c "source /home/iris/env/bin/activate && python /home/iris/entrypoint.py" and it seems to work.

I followed instructions from here https://github.com/linkedin/iris/tree/master/ops/packer

Same problem here. The packer configs use very old Ubuntu too, 16:04, and most of the python scripts use #!/usr/bin/env python instead of #!/usr/bin/env python3, which causes a lot of issues.

I have a bunch of enhancements to documentation and Dockerfile and packer setup, that should resolve this. This also updates to python3 , newer ubuntu, and improves the entrypoint mechanism.

I will send it in coming days.

@baryluk I haven't seen your work in your fork so far and had to move on with the Docker image myself. Sent a PR for it, https://github.com/linkedin/iris/pull/649.

I guess we can consolidate, split the changes afterwards.

This is solved by clearing ENTRYPOINT directive for the image. See my PR.

It depends on what is your preferred distribution channel and wider context of deployments you want to support. If you limit yourself to Docker and fill the image/OS with just python v3, you don't need to explicitly say python3 in hash-bang declarations. I did that in my PR.

I also found that lot of work has been done in https://github.com/allwyn-pradip/iris/tree/fw-iris.
