how to use files in script after cloning a repository?

I'd like to use some files that comes from a repository. The ideal use case is: - clone the repository, using module "git-clone" - use a file from this repository as the script parameter of resource "coder_script"

I tried a workaround and used the

depends_on

depends_on

parameter in a coder_script resource. but the call happen before the clone is done. the part of the template is:

module "git-clone" {
  source      = "registry.coder.com/modules/git-clone/coder"
  version     = "1.0.18"
  agent_id    = coder_agent.main.id
  url         = "https://github.com/devrel-workshop/101-AI-Enpoints"
  branch_name = "add-coder-template-files"
  order       = 1
}

resource "coder_script" "setup_script" {
  agent_id     = coder_agent.main.id
  display_name = "Create all needed environment variables"
  run_on_start = true
  script = templatefile("${path.module}/setup.sh", {
  })
  depends_on = [ module.git-clone ]
}

module "git-clone" {
  source      = "registry.coder.com/modules/git-clone/coder"
  version     = "1.0.18"
  agent_id    = coder_agent.main.id
  url         = "https://github.com/devrel-workshop/101-AI-Enpoints"
  branch_name = "add-coder-template-files"
  order       = 1
}

resource "coder_script" "setup_script" {
  agent_id     = coder_agent.main.id
  display_name = "Create all needed environment variables"
  run_on_start = true
  script = templatefile("${path.module}/setup.sh", {
  })
  depends_on = [ module.git-clone ]
}

and I add a setup.sh file in the Coder template configuration.

#!/bin/bash
# we are supposed to find the cloned repository
101-AI-Enpoints/setup_env.sh

#!/bin/bash
# we are supposed to find the cloned repository
101-AI-Enpoints/setup_env.sh

the thing I try to obtain was done with Gitpod previously. the code is public in https://github.com/devrel-workshop/101-AI-and-py the .gitpod.ym file was sourcing a script (yeah, I have still a lot of road to go with Coder to do the same 😉 )

image: bdmxla3s.gra7.container-registry.ovh.net/workshop_ia/101_ia:1.3.2

tasks:
  - name: Activate proper python and create environment file
    init: echo 'init script' # runs during prebuild => https://www.gitpod.io/docs/configure/projects/prebuilds
    command: |
      source /home/gitpod/venv/bin/activate
      source ./setup_env.sh

try setting depends_on = [ coder_script.git_clone ] honestly it looks like you might be better off with devcontainers given your workflow i've seen this issue in the past before though, we might want to add a run_after_clone argument or something

TitiMobyOP•4w ago

I know, we already have a devcontainer for local dev in case of network issue. But I thought this feature was still alpha I'm trying this

Phorcys•4w ago

not anymore!

Phorcys•4w ago

ah yeah I think you should do the cloning directly in your coder_script

TitiMobyOP•4w ago

so I tried the "baby steps" approach but since the beginning I knew the devcontainer was the way

Phorcys•4w ago

the issue is that with the module i don't think you have any way to know when it's done cloning

TitiMobyOP•4w ago

but in the end, I won't be able to source the script to have environment variable... so let's have a look at devcontainer

Phorcys•4w ago

why not?

#!/bin/bash
git clone "https://github.com/devrel-workshop/101-AI-Enpoints" -b "add-coder-template-files"

101-AI-Enpoints/setup_env.sh

#!/bin/bash
git clone "https://github.com/devrel-workshop/101-AI-Enpoints" -b "add-coder-template-files"

101-AI-Enpoints/setup_env.sh

this isn't the prettiest but it should do the job

TitiMobyOP•4w ago

I understood this but you won't be able to have env variable in the end except if coder_script has a syntax to

source setup.sh

source setup.sh

Phorcys•4w ago

@Atif do you have another idea? oh so you mean that the env variables have to be defined in the terminal session when a user opens it?

TitiMobyOP•4w ago

yes, this was the way we were able to provide the attendee a full environment for the workshop with specific env variables as API token and such

Phorcys•4w ago

i see what you mean yeah except adding it to /etc/profile.d or the .bashrc/.whateverrc i don't think there's a straightforward way to infer env variables from coder_scripts

TitiMobyOP•4w ago

If this useful, I can describe the compete use case to you or any interested product manager or tech lead being able to have those variable is the base for our workshop. do you think this is possible with the devcontainer approach?

Phorcys•4w ago

well, i don't think devcontainers would solve this issue really because devcontainers still need the variable to be set at some point at build time (of the image) except doing something like this, i'm not sure how you would achieve that

#!/bin/bash
echo "101-AI-Enpoints/setup_env.sh" >> $HOME/.bashrc

#!/bin/bash
echo "101-AI-Enpoints/setup_env.sh" >> $HOME/.bashrc

I can hop on a call if you want

TitiMobyOP•4w ago

I'm available for the next 20 minutes, I don't know if it is possible for you
