Run provider on Terraform Cloud

[volodymyrZotov]

Summary

With the latest stable version v1.4.0 it's not possible to run the provider on Terraform Cloud.

The attempt to fix it was done in v1.4.1-beta01, but requires additional efforts from the user to make it work. See details in this thead

The purpose of this issue to make the usage on Terraform Cloud smooth for the users and in the way that requires minimal efforts to run it.

Use cases

Run provider on Terraform Cloud.

Proposed solution

If the provider is running on the Terraform Cloud, install op-cli during provider initialization and use it. The minimum OP CLI version should be v2.23.0.

Is there a workaround to accomplish this today?

No

The following Dockerfile can build a custom tfc-agent image to provide op out of the box. However, this only works if you pay for custom runners in TFC.

To make this work on cloud and self hosted agents, you can use this workaround that we've been using on TFC for a long time now.

resource "terraform_data" "install_op_cli" {
  input = timestamp()

  triggers_replace = [
    timestamp()
  ]

  provisioner "local-exec" {
    command = <<EOH
    ARCH="amd64"; \
    OP_VERSION="v$(curl https://app-updates.agilebits.com/check/1/0/CLI2/en/2.0.0/N -s | grep -Eo '[0-9]+\.[0-9]+\.[0-9]+')"; \
    curl -sSfo op.zip \
    https://cache.agilebits.com/dist/1P/op2/pkg/"$OP_VERSION"/op_linux_"$ARCH"_"$OP_VERSION".zip \
    && mkdir tools \
    && unzip -od tools op.zip \
    && rm op.zip \
    && chmod 0755 tools/op \
    && export PATH="$PATH:$(pwd)/tools" \
    && echo $PATH \
    && op --version
EOH
  }
}

provider "onepassword" {
  # ...
  op_cli_path           = "./tools/op"
}

If you want a specific version, you can tweak as needed.

@MXfive how do you handle subsequent plan runs where it tries to read the previously created resources? I was able to create the resource without issues in the plan stage as long as I have depends_on = [terraform_data.install_op_cli] but follow-up plan runs result in

Error: 1Password Item read error
│ 
│   with onepassword_item.test,
│   on 1password_test.tf line 47, in resource "onepassword_item" "test":
│   47: resource "onepassword_item" "test" {
│ 
│ Could not get item '<redacted>' from vault
│ '<redacted>', got error: failed to get version of op CLI:
│ failed to execute command: fork/exec ./tools/op: no such file or directory

Operation failed: failed running terraform plan (exit 1)

Ah that really sucks. I'm only using the data source, not resource. So its expected to not be known at plan time.
