fix: Propagate CGO_ENABLED environment variable to docker build #724

burdzwastaken · 2024-03-21T23:00:52Z

Description

This PR aims to enable the generation of statically linked binaries for increased portability and ease of deployment. Selfishly we would like to use your upstream docker images and copy the binary across to our internal base image so we can use a tool like dependabot/renovate to keep up to date with the latest version.

Please let me know if you would like this be handled in a different way

Changes

Updated the Makefile to conditionally set CGO_ENABLED=0 when the STATIC flag is provided.
Ensured that the STATIC flag can be toggled via the Makefile, allowing flexibility in the build process.

FYI docker images are already built with CGO_ENABLED=0 by default. Relevant config piece: https://github.com/sosedoff/pgweb/blob/master/.github/workflows/release.yml#L10

burdzwastaken · 2024-03-23T06:37:10Z

I don't believe that env var it is being passed along to the docker image

sorry for missing the env var in the GitHub action, I'm happy to adjust my PR to pass the supplied env var in your GitHub action along to the docker build step

sosedoff · 2024-03-24T18:48:53Z

Hm i thought Actions env vars get propagated to steps without additional configuration, are you saying this is not the case with Pgweb?

burdzwastaken · 2024-03-25T11:12:25Z

actions environment variables get propagated to the steps however since the build is inside docker it does not inherit them. to handle this I propose we can use ARG and ENV inside docker and pass it along from actions via build-args. here is a sample pipeline I created to show the difference in behaviour:
branch: https://github.com/sosedoff/pgweb/compare/master...burdzwastaken:pgweb:statically-compiled-binaries-envvar?expand=1
build: https://github.com/burdzwastaken/pgweb/actions/runs/8419078468/job/23050925506

the change then which I am happy to make on my branch is to remove the make target that I added and update the Dockerfile/github actions files like so

sosedoff · 2024-03-26T04:55:06Z

You're totally right about the env var propagation.

burdzwastaken · 2024-03-26T10:00:11Z

PR updated to just propagate the environment variable that already exists in the github action

burdzwastaken · 2024-03-27T05:52:37Z

@sosedoff thanks for merging, do you mind cutting a release so we can utilise the changes in docker behaviour?

sosedoff · 2024-03-27T06:13:11Z

I'll do some testing before cutting a new release but that should not take too long.

burdzwastaken · 2024-03-27T06:16:21Z

@sosedoff thank you so much and I appreciate your efforts maintaining this great tool
