Fixed - How to make "terraform get" works with mercurial (hg) repository

Drone Support
1

I used plugins/hg to download mercurial repo successfully.

clone:
  hg:
    image: plugins/hg
    path: bitbucket.org/orig/project-1

Doesn’t work with hg (mercurial repository)

But in terraform, to download terraform modules, I have below codes:

module "app" {
   source = "hg::https://bitbucket.org/orig/project-1?rev=default"
   ....
}

When run terraform get, it will download related modules (mercurial repositories) via hg command. I run this successfully on my laptop.

But have problem to run it in drone with container hashicorp/terraform.

The exist official hashicorp/terraform image only supports git, not mercurial command hg. That’s fine. I create an image with this command:

$ cat Dockerfile
FROM hashicorp/terraform:0.10.3

RUN apk add --no-cache mercurial

I set this pipeline:

  build:
    image: 1234567890.dkr.ecr.ap-southeast-2.amazonaws.com/terraform:0.10.3-hg
    commands:
      - terraform get --update=true
      - terraform init -backend-config=config/backend-${env}.conf
      - terraform plan -var-file=config/${env}.tfvars -input=false -out=plan

Then I get authorization issue with new image:

Works in git

I have another project with below pipeline, which use git as version control. I can run terraform get in drone pipeline to download terraform module directly without any issue.

module "app" {
   source = "git::https://bitbucket.org/orig/project-1?rev=default"
   ....
}

Pipeline:

  build:
    image: hashicorp/terraform:0.10.3
    commands:
      - terraform get --update=true
      - terraform init -backend-config=config/backend-${env}.conf
      - terraform plan -var-file=config/${env}.tfvars -input=false -out=plan

My questions:

How to fix this issue.

I am curious, how clone plugins/hg works to download mercurial private repository without having this authorization issue.

How plugins/git works with private repositories. How plugins/git and plugins/hg know and use the environment DRONE_BITBUCKET_CLIENT and DRONE_BITBUCKET_SECRET to download private repositories

I fixed the problem.

Since terraform get works well with git, I re-create the terraform module with git.
