Git

Styra Load's support for pulling in data from any Git repository makes it possible to use GitOps practices for managing data and have that data available for policy evaluations in Styra Load.

Example Configuration

The Git integration is provided via the data plugin, and needs to be enabled in Load's configuration.

load-conf.yaml (minimal)

plugins:
  data:
    git.users:
      type: git
      url: https://git.internal.corp/data-repository
      file_path: users.json

With this minimal configuration, Styra Load will pull in the users.json file from the repository's main branch every 30 seconds.

All of this, and various authentication methods, can be configured using an advanced configuration:

load-conf-advanced.yaml

plugins:
  data:
    git.users:
      type: git
      url: https://git.internal.corp/data-repository
      file_path: users.json
      commit: 73b9d1aefab          # if empty, use `branch` (default: none)
      branch: prod-branch          # if empty, use `reference` (default: none)
      reference: ref/heads/main    # full git reference
      polling_interval: 10m        # default: 30s, minimum 10s

      username: alice              # basic auth
      password: wordpass           # basic auth

      token: personal-access-token # token auth

      private_key: path/to/key     # SSH key, file path or PEM contents
      passphrase: secret           # passphrase for protected keys

With a config like this, Styra Load will retrieve the file from the specified repository location, and attempt to parse as any of:

• XML
• YAML
• JSON

The result will then be available to all policy evaluations under data.git.users.

Example Call

If the referenced Git repository contains a users.json file with this content,

[
    {"username": "alice", "roles": ["admin"]},
    {"username": "bob", "roles": []},
    {"username": "catherine", "roles": ["viewer"]}
]

then Styra Load's data.git.users will look like this:

$ curl 'http://127.0.0.1:8181/v1/data/git/users?pretty'
{
  "result": [
    {
      "roles": [
        "admin"
      ],
      "username": "alice"
    },
    {
      "roles": [],
      "username": "bob"
    },
    {
      "roles": [
        "viewer"
      ],
      "username": "catherine"
    }
  ]
}

note

The key below data in the configuration (git.users in the example) can be anything you want, and determines where the retrieved document will be found in Styra Load's data hierarchy.
