forj-oss / build-env Goto Github PK

Today, the go wrapper run docker run to execute the go container.
Creating and deleting the container takes times which can be eliminated by a docker run + exec(s)

We would use this kind of features in Jenkins pipeline as well, so that Jenkins will have more stages while those steps can be executed from developer workstation, and have a global script to execute all those stages as single task.

Related to forj-oss/forjj#207, a source to build-env.sh report an error in order to run create_build-env.sh which doesn't exist.

The issue is related to https://github.com/forj-oss/build-env/blob/master/lib/build-env.fcts.sh#L53 which is referring to GO in generic shell code.

Need to be fixed.

Docker multistage is another great new feature from docker which will simplify how we build and deliver in a final small image.

This was addressed in the GO module of build-env, but is a little bit complex and simplified by the module.
But the code itself could simplified as well now again.

Ref: https://docs.docker.com/develop/develop-images/multistage-build/

• function name
• module functions required

Module : GO

After build_env script executed, the build environment gets loaded, and go and glide became available.

When you are in project root, go start docker from the project root.
But if we move to a subdirectory, docker stay in the same working directory. But sometimes, we just need a simple module build and not all the application build.

Ex:
Following looks good:

[/home/larsonsh/src/forj/src/forjj] $ go build
++ sudo docker run --rm -i -t -v /home/me/src/forj/:/go -w /go/src/forjj -u 10001 forjj-go-env /usr/local/go/bin/go-static build -ldflags '-X main.build_branch=workspace-mgt -X main.build_commit=6ac25087d1fc45d4662d082943068129e4712f55 -X main.build_date=2018-09-06_22:18:07_+0200 -X main.build_tag=false'

Following do not looks good:

[/home/larsonsh/src/forj/src/forjj/workspace] $ go build
++ sudo docker run --rm -i -t -v /home/me/src/forj/:/go -w /go/src/forjj -u 10001 forjj-go-env /usr/local/go/bin/go-static build -ldflags '-X main.build_branch=workspace-mgt -X main.build_commit=6ac25087d1fc45d4662d082943068129e4712f55 -X main.build_date=2018-09-06_22:18:07_+0200 -X main.build_tag=false'

This last sentence build from the project root and not from project root/workspace

Requires to build only the sub-directory.
