Updating $PATH while running a bitbucket pipeline

[Misha (HS)]

I'm working with hashicorp/terraform:latest image (which is very minimal) and need to install go. After installing go into /usr/local. As a next step we need to update $PATH so that we could run go commands. But the export PATH does not take and the shell can't find go executable which is in /usr/local/go/bin.

We can't quite figure out how to go about this. Help is greatly appreciated!

```

image: hashicorp/terraform:latest

pipelines:

branches:

dev:

- step:

name: Build & deploy [dev]

# image: golang

deployment: Dev

script:

- apk add bash

- apk add zip

- source bitbucket-pipelines.sh

- cd ${IMPORT_PATH}

# Install go

- wget https://golang.org/dl/go1.17.2.linux-amd64.tar.gz

- tar -C /usr/local -xzf go1.17.2.linux-amd64.tar.gz

- ls -la /usr/local/go/bin

- export PATH=$PATH:/usr/local/go/bin

- echo $PATH

- echo $0 # show shell exec

- go version # this fails with file not found

```

Hi @Misha (HS),

I have tried to reproduce this locally by running a Docker container with the image you are using:

docker run -it --entrypoint=/bin/sh hashicorp/terraform:latest

and then I executed the commands you have in your yml file (apart from lines 3 and 4 of the script)

The command go version also fails when debugging this locally.

If I try the installation in a different Docker container, e.g. atlassian/default-image:3 which is based on Ubuntu, the installation of go seems to succeed (both locally and in Pipelines).

It is possible that the file you are downloading is not the correct one for Alpine Linux or extra/different steps may be needed for the installation in Alpine. I'm afraid I don't know what exactly is causing the problem here, but it seems to be specific to the Linux distribution of the Docker image.

Kind regards,
Theodora

Oh, great, thank you Theodora. I will play with the image. It looks like Alpine does not like the compiled for amd64 go binary. I will update this ticket with what I find.

Pre-compiled go binary seems not to be compatible with alpine.

You can see an example of how to build go from source on alpine at this dockerfile
https://github.com/docker-library/golang/blob/67757c0feeb9867a54801ca378dcfc55b9db7e70/1.17/alpine3.15/Dockerfile

Better option would be as suggested already by Atlassian team to use another image based on Debian / Ubuntu

Thanks for posting that example Jack!

@Misha (HS), I also found the following blog post, the solution suggested there is to install go with apk:

Hi there maybe you must add execution permissions to go binary?

chmod a+x /usr/local/go/bin/go

[Misha (HS)]

What I'm getting is file not found (not a permission issue)
