In addition to defining services through OpsLevel’s UI and GraphQL API, you can also define services by placing a YAML file named opslevel.yml in a service’s repo. Leveraging our Git Repository Integrations, OpsLevel will automatically synchronize the contents of the opslevel.yml file whenever it changes. This config-as-code mechanism allows developers to retain their existing Git-based development workflows to keep this data up-to-date.
In addition to services, opslevel.yml can also track ownership and metadata about repositories. The contents of opslevel.yml differ depending on if it’s tracking a service or a repository. The schema below highlights these differences.
opslevel.yml uses human readable identifiers to specify the owner, or tier of a service or repository, as well as the lifecycle stage of a service. For example, an opslevel.yml that specifies the team that owns a service looks like:
service: name: Order Processor owner: orders_team
The identifier orders_team is an alias. Aliases are automatically generated by OpsLevel for teams, tiers, and lifecycles.
Finding the alias for a team
Navigate to a Team page. There you can find the team alias.
Finding the alias for a tier
Navigate to the Account page. From there you will see a list of all your Service Tiers and their aliases. Currently, only users with the Admin role have access to the Account page. Non-Admin users can access this information with the OpsLevel CLI using the opslevel list tier command.
Finding the alias for a lifecycle
Similar to Service Tiers, navigate to the Account page. From there you will see a list of all your Service Lifecycles and their aliases. Currently, only users with the Admin role have access to the Account page. Non-Admin users can access this information with the OpsLevel CLI using the opslevel list lifecycle command.
Aliases are stable identifiers. If you rename an entity that has an alias (e.g., a team), OpsLevel will generate a new alias. However, the old alias will still be valid so any existing references to it from other opslevel.yml files will continue to work.
Converting an existing service to use opslevel.yml
If you have a service already defined in OpsLevel and want it to be managed with opslevel.yml, first ensure the service is already connected to a repo. When a service is connected to a repo, OpsLevel will know how to merge a newly detected opslevel.yml with the service. After the repo is connected to the service, you can download the service’s YAML file and commit it to the repo.
Step 1: Visit a service’s Operation tab and select the repository your service lives in from the Repository Center by clicking Edit and + Add Repository.
Step 2: From the service page click the Download YAML button.
Step 3: Copy or Download the YAML and commit to the repo you selected in Step 1.
Converting an existing repository to use opslevel.yml
You can use opslevel.yml to manage properties directly on a repository, such as: owner, tier, and tags.
Step 1: Select a repository that was imported using one of our Git Repository Integrations.
Step 2: From the repository page click the Download YAML button.
Step 3: Copy or Download the YAML and commit to this repo.
The following tables provide an in depth list of all the properties supported by opslevel.yml.

|provider||true||The git provider where your repository is stored.|
|display_name||false||The repository name displayed on the service page.|
|path||false||The path repository containing the opslevel.yml and where repository checks are applied. This is useful in monorepo situations where multiple services are contained in one repository.|

You can automatically validate your opslevel.yml file as part of your CI using the following JSON schema: opslevel.schema.yml
You can run the following command which uses ajv-cli.
ajv test -s opslevel.schema.yml -d opslevel.yml --valid
When a service or repository is managed by opslevel.yml, certain fields are locked for edit in the UI. This ensures that there is never a conflict between what’s defined in opslevel.yml and what’s defined in the UI.
For services the name, description, owner, tier, lifecycle stage, language, and framework fields are all locked for editing.
For repositories the owner and tier fields are locked for editing.
Service and repository properties that are lists, such as tools, tags, aliases, dependencies, and repositories, can have new entries added in the UI, though existing entries defined in opslevel.yml will be locked.
As shown in the image below, to tell whether a service or repository is managed by opslevel.yml, you can look for a lock icon on the respective information page.
Locked Service Dependency
Example service opslevel.yml
version: 1 service: name: Shopping Cart Service lifecycle: generally_available tier: tier_1 product: Retail Website owner: order_management_team language: Ruby framework: Rails description: Allows users to add/remove products in their virtual shopping carts prior to placing an order. aliases: - cart tags: - key: db value: mysql - key: kafka-topic value: cart-additions repositories: - name: DunderMifflin/shopping_cart path: "/" provider: github display_name: Cart Service Code - name: DunderMifflin/TerraformRepo path: "/production/shopping_cart" provider: bitbucket display_name: Terraform Config tools: - name: Confluence category: runbooks url: http://company.atlassian.com/confluence/runbooks - name: PagerDuty category: incidents url: https://your_account.pagerduty.com/services/PH99999 environment: Production - name: Datadog category: metrics url: https://app.datadog.com/your_dashboard?env=prod environment: Production - name: Datadog category: metrics url: https://app.datadog.com/your_dashboard?env=staging environment: Staging dependencies: - alias: recommendation_service notes: Provides products recommendations to enhance the users shopping experience - alias: suggestions_service
Example repository opslevel.yml

If your organization uses template repositories for creating new services or repositories, you will benefit from using opslevel.defaults.yml as a templating mechanism.
opslevel.defaults.yml allows you to specify default values for your services or repositories that will be applied once you add an opslevel.yml file. Values set in the opslevel.defaults.yml file will be overwritten by values from the opslevel.yml file.
It is recommended you add an opslevel.defaults.yml file to your template repository with some basic defaults set; these are often in the form of a default language/framework, default tags, default tools, and possibly more.
The format of opslevel.defaults.yml is identical to that of opslevel.yml. The only difference is that the opslevel.defaults.yml file limits which values you can set.
Values you can set from opslevel.defaults.yml:
Where do I put the opslevel.yml file?
Just add your opslevel.yml file(s) to your repo. If you specify a service definition in this file and this repo isn’t already mapped to a service in OpsLevel, a new service will be created.
Note: OpsLevel will only look for files that use the .yml extension.
I have two services that are both locked by the same repo and opslevel.yml, how do I delete the duplicate service if it’s a duplicate?
If you attach a repo to a service that is already locking a different service, we will apply the opslevel.yml to the new service and subsequently lock it.
In order to delete this service, you must first delete the repository connection on the duplicate service, which will unlock the service and allow you to delete it.
