Warning The provider is under active development and will initially support only some Juju functionality. Use releases at your own risk.

The provider can be used to interact with Juju - an open source orchestration engine.

Today this provider allows you to manage the following via resources:

• Applications and deploy charms
• Credentials for existing clouds
• Integrations
• Machines
• Models
• Model ssh keys
• Offers
• Users

and refer to the following via data sources:

• Machines
• Models
• Offers

Note: These features may not have functional parity with the juju CLI at this time.

• Terraform >= 1.6
• Go >= 1.21

1. Clone the repository

2. Enter the repository directory

3. Build the provider dependencies using the make install-dependencies target:

   make install-dependencies

4. Build the provider using the make go-install target:

   make go-install

5. Install in ~/.terraform.d/plugins with

   make install

Please run make to see other targets available, including formatting, linting and static analysis.

Please, refer to the Terraform docs for the Juju provider.

Note: Commits provided as part of a PR must be signed via git for the PR to merge.

When creating a new resource, datasource or changing a current schema please document the changes and create an github issue for review and approval before coding.

Consider writing documents for the project-docs/decisions folder.

New resources and datasources will require import and use example documents.

If you wish to work on the provider, you'll first need Go installed on your machine (see Requirements above).

Prior to running the tests locally, ensure you have the following environmental variables set:

• JUJU_CONTROLLER_ADDRESSES
• JUJU_USERNAME
• JUJU_PASSWORD
• JUJU_CA_CERT

For example, here they are set using the currently active controller:

export CONTROLLER=$(juju whoami | yq .Controller)
export JUJU_CONTROLLER_ADDRESSES="$(juju show-controller | yq '.[$CONTROLLER]'.details.\"api-endpoints\" | tr -d "[]' "|tr -d '"'|tr -d '\n')"
export JUJU_USERNAME="$(cat ~/.local/share/juju/accounts.yaml | yq .controllers.$CONTROLLER.user|tr -d '"')"
export JUJU_PASSWORD="$(cat ~/.local/share/juju/accounts.yaml | yq .controllers.$CONTROLLER.password|tr -d '"')"
export JUJU_CA_CERT="$(juju show-controller $(echo $CONTROLLER|tr -d '"') | yq '.[$CONTROLLER]'.details.\"ca-cert\"|tr -d '"'|sed 's/\\n/\n/g')"

Then, finally, run the Acceptance tests:

make testlxd

And

make testmicrok8s

Note: Acceptance tests create real resources.

To simplify staying in sync with upstream, give it a "remote" name:

git remote add upstream https://github.com/juju/terraform-provider-juju.git

Make sure your local copy and GitHub fork stay in sync with upstream:

git pull upstream/main --rebase

Merge commits for sync actions will be rejected.

This provider uses Go modules. Please see the Go documentation for the most up to date information about using Go modules.

To add a new dependency github.com/author/dependency to your Terraform provider:

go get github.com/author/dependency
go mod tidy

Then commit the changes to go.mod and go.sum.

To debug, setup environment variables:

export TF_LOG_PROVIDER=TRACE ; export TF_LOG_PATH=./terraform.log

Run your terraform commands.

To find logs specific to the juju provider code:

grep "@module=juju.resource" ./terraform.log
grep "@module=juju.datasource" ./terraform.log

To find logs specific to the juju client talking to juju itself:

grep "@module=juju.client" ./terraform.log
