# Validate `.gitlab-ci.yml` syntax with the CI Lint tool
|
|
|
|
If you want to test the validity of your GitLab CI/CD configuration before committing
|
|
the changes, you can use the CI Lint tool. This tool checks for syntax and logical
|
|
errors by default, and can simulate pipeline creation to try to find more complicated
|
|
issues as well.
|
|
|
|
To access the CI Lint tool, navigate to **CI/CD > Pipelines** or **CI/CD > Jobs**
|
|
in your project and click **CI lint**.
|
|
|
|
## Validate basic logic and syntax
|
|
|
|
By default, the CI lint checks the syntax of your CI YAML configuration and also runs
|
|
some basic logical validations. Configuration added with the [`includes` keyword](yaml/index.md#include),
|
|
is also validated.
|
|
|
|
To use the CI lint, paste a complete CI configuration (`.gitlab-ci.yml` for example)
|
|
into the text box and click **Validate**:
|
|
|
|
|
|
|
|
## Pipeline simulation
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/229794) in GitLab 13.3.
|
|
|
|
Not all pipeline configuration issues can be found by the [basic CI lint validation](#validate-basic-logic-and-syntax).
|
|
You can simulate the creation of a pipeline for deeper validation that can discover
|
|
more complicated issues.
|
|
|
|
To validate the configuration by running a pipeline simulation:
|
|
|
|
1. Paste the GitLab CI configuration to verify into the text box.
|
|
1. Select the **Simulate pipeline creation for the default branch** checkbox.
|
|
1. Select **Validate**.
|
|
|
|
|
|
|
|
### Pipeline simulation limitations
|
|
|
|
Simulations run as `git push` events against the default branch. You must have
|
|
[permissions](../user/permissions.md#project-members-permissions) to create pipelines
|
|
on this branch to validate with a simulation.
