| title: Deploying Machine ID on Bitbucket Pipelines | ||
| description: How to install and configure Machine ID on Bitbucket Pipelines | ||
| --- | ||
|
|
||
| In this guide, you will configure Machine ID's agent, `tbot`, to run within a | ||
| Bitbucket Pipelines workflow. The bot will be configured to use the `bitbucket` | ||
| delegated joining method to eliminate the need for long-lived secrets. | ||
|
|
||
| ## Prerequisites | ||
|
|
||
| (!docs/pages/includes/edition-prereqs-tabs.mdx!) | ||
|
|
||
| - (!docs/pages/includes/tctl.mdx!) | ||
| - A Bitbucket repository you can push to. | ||
|
|
||
| ## Step 1/4. Determine Bitbucket configuration | ||
|
|
||
| Bitbucket joining requires a number of configuration parameters that can be | ||
| found in your repository settings. From the Bitbucket repository, navigate to | ||
| "Repository settings", then in the sidebar under "Pipelines" select "OpenID | ||
| Connect". | ||
|
|
||
| From this page, note the following values: | ||
| - Identity provider URL (<Var name="identity-provider-url" />) | ||
| - Audience (<Var name="audience" />) | ||
| - Workspace UUID (<Var name="workspace-uuid" />) | ||
| - Repository UUID (<Var name="repository-uuid" />) | ||
|
|
||
| ## Step 2/4. Create the Machine ID bot | ||
|
|
||
| (!docs/pages/includes/machine-id/create-a-bot.mdx!) | ||
|
|
||
| ## Step 3/4. Create the join token for Bitbucket Pipelines | ||
|
|
||
| In order to allow your Pipelines workflow to authenticate with your Teleport | ||
| cluster, you'll first need to create a join token. These tokens set out criteria | ||
| by which the Auth Server decides whether or not to allow a bot or node to join. | ||
|
|
||
| Create a file named `bot-token.yaml`, ensuring that you replace the | ||
| `identity_provider_url`, `audience`, `workspace_uuid`, and `repository_uuid` | ||
| with the values from Step 1. | ||
|
|
||
| ```yaml | ||
| kind: token | ||
| version: v2 | ||
| metadata: | ||
| name: example-bot | ||
| spec: | ||
| roles: [Bot] | ||
| join_method: bitbucket | ||
| bot_name: example | ||
| bitbucket: | ||
| identity_provider_url: <Var name="identity-provider-url" /> | ||
| audience: <Var name="audience" /> | ||
| # allow specifies the rules by which the Auth Server determines if `tbot` | ||
| # should be allowed to join. | ||
| allow: | ||
| - workspace_uuid: <Var name="workspace-uuid" /> | ||
| repository_uuid: <Var name="repository-uuid" /> | ||
| ``` | ||
| Let's go over the token resource's fields in more detail: | ||
| - `metadata.name` defines the name of the token. Note that this value will need | ||
| to be used in other parts of the configuration later. | ||
| - `spec.bot_name` is the name of the Machine ID bot that this token will grant | ||
| access to. Note that this value will need to be used in other parts of the | ||
| configuration later. | ||
| - `spec.roles` defines which roles that this token will grant access to. The | ||
| value of `[Bot]` states that this token grants access to a Machine ID bot. | ||
| - `spec.join_method` defines the join method the token is applicable for. Since | ||
| this guide only focuses on Bitbucket Pipelines, you will set this to to | ||
| `bitbucket`. | ||
| - `spec.bitbucket.identity_provider_url` is the identity provider URL shown in | ||
| the Bitbucket repository settings, under Pipelines and OpenID Connect. | ||
| - `spec.bitbucket.audience` is the audience value shown in the Bitbucket | ||
| repository settings, under Pipelines and OpenID connect. | ||
| - `spec.bitbucket.allow` is used to set rules for what Bitbucket Pipelines runs | ||
| will be able to authenticate by using the token. | ||
|
|
||
| Refer to the [token reference](../../../reference/join-methods.mdx#bitbucket-pipelines-bitbucket) | ||
| for a full list of valid fields. | ||
|
|
||
| Apply this to your Teleport cluster using `tctl`: | ||
|
|
||
| ```code | ||
| $ tctl create -f bot-token.yaml | ||
| ``` | ||
|
|
||
| ## Step 4/4. Configure a Bitbucket Pipelines workflow | ||
|
|
||
| With the bot and join token created, you can now configure a workflow that can | ||
| authenticate to Teleport. | ||
|
|
||
| This example workflow defines a "custom" pipeline that can be triggered manually | ||
| from "Pipelines" or "Branches" views: | ||
|
|
||
| ```yaml | ||
| image: atlassian/default-image:3 | ||
| pipelines: | ||
| custom: | ||
| run-tbot: | ||
| - step: | ||
| oidc: true | ||
| script: | ||
| # Download and extract Teleport | ||
| - wget https://cdn.teleport.dev/teleport-v(=teleport.version=)-linux-amd64-bin.tar.gz | ||
| - tar -xvf teleport-v(=teleport.version=)-linux-amd64-bin.tar.gz | ||
| # Run `tbot` in identity mode for SSH access | ||
| - ./teleport/tbot start identity --destination=./tbot-user --join-method=bitbucket --proxy-server=example.teleport.sh:443 --token=bot-bitbucket --oneshot | ||
|
|
||
| # Make use of the generated SSH credentials | ||
| - ssh -F ./tbot-user/ssh_config [email protected] echo "hello world" | ||
| ``` | ||
| This example will start `tbot` in identity mode to generate SSH credentials. | ||
| Refer to the [`tbot start` documentation](../../../reference/cli/tbot.mdx#tbot-start) | ||
| for details on using other modes such as database, application, and Kubernetes | ||
| access. | ||
|
|
||
| If you're adapting an existing workflow, note these steps: | ||
| 1. Set `oidc: true` on the step properties so that step will be issued a token | ||
| 1. Download and extract a `.tar.gz` Teleport build | ||
| 1. Run `tbot` with `--join-method=bitbucket`, `--token=example-bot` (or | ||
| whichever name was configured in Step 3), and `--oneshot` | ||
|
|
||
| <Admonition type="warning" title="Sharing credentials between steps"> | ||
| Note that in Bitbucket Pipelines, outputs cannot be securely shared between | ||
| steps as anything stored using `artifacts` will remain downloadable once the CI | ||
| run has completed. | ||
|
|
||
| Due to this limitation, all operations making use of Teleport credentials should | ||
| be performed as part of the same step. If necessary, you can duplicate the | ||
| script shown here to download and run `tbot` multiple times in a given run if | ||
| credentials are needed in multiple steps. | ||
| </Admonition> | ||
|
|
||
| ## Further steps | ||
|
|
||
| - Follow the [access guides](../access-guides/access-guides.mdx) to finish configuring `tbot` for | ||
| your environment. | ||
| - Read the [configuration reference](../../../reference/machine-id/configuration.mdx) to explore | ||
| all the available configuration options. | ||
| - For more information about Bitbucket Pipelines itself, read | ||
| [their documentation](https://support.atlassian.com/bitbucket-cloud/docs/get-started-with-bitbucket-pipelines/). | ||
