Sourcegraph Instance Validation

Sourcegraph Validation is currently experimental.

Validate Sourcegraph Installation

Installation validation provides a quick way to check that a Sourcegraph installation functions properly after a fresh install or an update.

The src CLI has an experimental command validate install which drives the validation from a user-provided configuration file with a validation specification (in JSON or YAML format). If no validation specification file is provided it will execute the following defaults:

temporarily adds an external service
waits for a repository to be cloned
performs a search on the cloned repo
performs a search on a non-indexed branch of the cloned repo
creates basic code insight
removes the added external service
removes the added code insight

Validation specification

Validation specifications can be provided in either a YAML or JSON format. The best way to describe this initial, simple, and experimental validation specification is with the example below:

YAML File Specification

YAML
# adds the specified code host
externalService:
  kind: GITHUB
  displayName: srcgraph-test
  # set to true if this code host config should be deleted at the end of validation
  deleteWhenDone: true
  # maxRetries amount of retries for cloning repo
  maxRetries: 5
  # retryTimeoutSeconds wait in seconds between retries
  retryTimeoutSeconds: 5
  config:
    gitHub:
      url: https://github.com
      orgs: []
      repos:
        - sourcegraph-testing/zap
 
# performs the specified search and checks that at least one result is returned
searchQuery:
  - repo:^github.com/sourcegraph-testing/zap$ test
  - repo:^github.com/sourcegraph-testing/[email protected] test
 
# checks to see if instance can create code insights

      "repositoryScope": [

      ],
      "lineColor": "#6495ED",
      "timeScopeUnit": "MONTH",
      "timeScopeValue": 1
    },
      {
        "query": "lang:typescript",
        "label": "typescript",
        "lineColor": "#DE3163",
        "repositoryScope": [
          "github.com/sourcegraph/sourcegraph"
        ],
        "timeScopeUnit": "MONTH",
        "timeScopeValue": 1
      }
    ]
  deleteWhenDone: true
 
# checks if there have been active executors in the past 15 minutes and returns the total count
executor:
  enabled: true
 
# tests the smtp configuration in instance site config by sending an email to the email address in smtp.to
smtp:
  enabled: true
  to: "[email protected]"

JSON File Specification

        ],
        "lineColor": "#6495ED",
        "timeScopeUnit": "MONTH",
        "timeScopeValue": 1
      },
      {

        "label": "typescript",
        "lineColor": "#DE3163",
        "repositoryScope": [
          "github.com/sourcegraph/sourcegraph"

      }
    ],
    "deleteWhenDone": true
  },
 
  "executor": {
    "enabled": true
  },
 
  "smtp": {
    "enabled": true,
    "to": "[email protected]"
  }
 
}

With this configuration, the validation command executes the following steps:

adds an external service
waits for a repository to be cloned
performs a search
removes the external service
creates a code insight
removes the code insight
checks the number of connected executor instances
sends a test email to confirm SMTP configuration

NOTE: Every step is optional (if the corresponding top-level key is not present then the step is skipped). Without setting executor.enabled and smtp.enabled explicitly to true, these steps will be omitted as they default to false.

Passing in secrets

Secrets are handled via environment variables. src validate install requires an environment variables to be set to authenticate to your code host.

NOTE: Currently only GitHub is supported as a code host.

src validate install requires an environment variable to be setup to authenticate against your code host.

SRC_GITHUB_TOKEN - defines the GitHub access token used to authenticate to the GitHub API. This must be set to use a GitHub code host.

Example:

BASH
export SRC_GITHUB_TOKEN=token

Usage

Use the src CLI to validate with a validation specification file:

SHELL
src validate install validate.yaml

SHELL
src validate install validate.json

To execute default validation checks:

SHELL
src validate install

The src binary finds the Sourcegraph instance to validate from the environment variables SRC_ENDPOINT and SRC_ACCESS_TOKEN.

Validate Sourcegraph Kubernetes Deployment

Kubernetes deployment validation provides a quick way to check that a Sourcegraph deployment on Kubernetes is configured correctly.

The src CLI has an experimental command validate kube which performs validation of a Sourcegraph deployment on Kubernetes. These validation checks include:

Pod validation
Service validation
Persistent Volume Claim (PVC) validation
Inter-Service network connection validation

These validations can also include warnings for non-failure states that should be addressed, e.g. high restart counts.

Cluster Authentication

Kubernetes cluster authentication is handled via a standard kubeconfig file. You can also use the --kubeconfig option to use a different configuration file. By default this program will use the default file used by kubectl.

Usage

Use the src CLI to validate Kubernetes deployment:

SHELL
src validate kube

Specify a non-default Kubernetes namespace:

SHELL
src validate kube --namespace sourcegraph

Specify a different kubeconfig file:

SHELL
src validate kube --kubeconfig ~/.kube/config

Silence output:

SHELL
src validate kube --quiet
