Integrate with Git

The Data Plane API integrates with Git, enabling you to sync load balancer configuration changes to a remote Git repository. The API serves as a Git client, providing commands to commit changes and push and pull from a remote repository.

Configure Git integration Jump to heading #

1. Create a new empty Git repository on your version control server (i.e. GitHub, GitLab, Jenkins).

2. Create an access token so that the Data Plane API can access your remote Git repository.

   • Create an access token on GitLab

   • Create an access token on GitHub

   • Create an access token on Jenkins

3. Configure the load balancer configuration directory as a Git clone:

   HAProxy HAProxy Enterprise HAProxy ALOHA

   nix
   cd /etc/haproxy
   git init
   git remote add origin https://github.com/username/repo.git
   git checkout -b main

   nix
   cd /etc/haproxy
   git init
   git remote add origin https://github.com/username/repo.git
   git checkout -b main

   nix
   cd /etc/hapee-<VERSION>
   git init
   git remote add origin https://github.com/username/repo.git
   git checkout -b main

   nix
   cd /etc/hapee-<VERSION>
   git init
   git remote add origin https://github.com/username/repo.git
   git checkout -b main

   nix
   cd /etc/haproxy
   git init
   git remote add origin https://github.com/username/repo.git
   git checkout -b main

   nix
   cd /etc/haproxy
   git init
   git remote add origin https://github.com/username/repo.git
   git checkout -b main

4. Set your username and email for commits.

   nix
   sudo git config --global user.name "Your Name"
   sudo git config --global user.email "name@example.com"

   nix
   sudo git config --global user.name "Your Name"
   sudo git config --global user.email "name@example.com"

5. Commit and push the local configuration files to the remote repository.

   nix
   sudo git add .
   sudo git commit -m "Initial commit"
   sudo git push origin main

   nix
   sudo git add .
   sudo git commit -m "Initial commit"
   sudo git push origin main

6. Add the file /etc/haproxy/git.settings:

   git.settings
   json
   {
     "url": "https://github.com/username/repo.git",
     "auth_method": "access_token",
     "auth_access_token": "C4Axa1kCcxPv-fzrhsde",
     "storage_type": "dir",
     "storage_dir": "/etc/haproxy/",
     "config_file": "haproxy.cfg"
   }

   git.settings
   json
   {
     "url": "https://github.com/username/repo.git",
     "auth_method": "access_token",
     "auth_access_token": "C4Axa1kCcxPv-fzrhsde",
     "storage_type": "dir",
     "storage_dir": "/etc/haproxy/",
     "config_file": "haproxy.cfg"
   }

   In this example:

   • url is the URL of your git repository
   • auth_access_token is your repository’s access token
   • storage_dir is the path to your load balancer configuration directory
   • config_file is the name of your configuration file

7. Edit your Data Plane API configuration file (for example, /etc/haproxy/dataplaneapi.yml).

   Add the git_mode and git_settings_file fields to the dataplaneapi block:

   dataplaneapi.yml
   yaml
   dataplaneapi:
     host: 0.0.0.0
     port: 5555
     git_mode: true
     git_settings_file: /etc/haproxy/git.settings

   dataplaneapi.yml
   yaml
   dataplaneapi:
     host: 0.0.0.0
     port: 5555
     git_mode: true
     git_settings_file: /etc/haproxy/git.settings

8. Restart the Data Plane API. If using the program section in your HAProxy configuration file, you can do this by restarting the HAProxy service:

   nix
   sudo systemctl restart haproxy

   nix
   sudo systemctl restart haproxy

   Otherwise, restart the Data Plane API service.

9. Use the pull action on the /services/git/actions API endpoint to sync remote changes to the local repository.

   nix
   curl -X POST \
     -u admin:adminpwd \
     -H 'Content-Type: application/json' \
     -d '{ "action":"pull"}' \
     '127.0.0.1:5555/v2/services/git/actions'

   nix
   curl -X POST \
     -u admin:adminpwd \
     -H 'Content-Type: application/json' \
     -d '{ "action":"pull"}' \
     '127.0.0.1:5555/v2/services/git/actions'

Sync changes with the remote repository Jump to heading #

Once the HAProxy configuration directory has been initialized as a local git clone, you can sync any changes by calling the commit and push actions.

For example, after adding a new server to an existing backend named webservers:

nix
CFGVER=$(curl -s -u admin:adminpwd http://localhost:5555/v2/services/haproxy/configuration/version)
curl -X POST \
  -u admin:adminpwd \
  -H "Content-Type: application/json" \
  -d '{"name":"anotherserver", "address":"127.0.0.1", "port":8080, "check":"enabled"}' \
  '127.0.0.1:5555/v2/services/haproxy/configuration/servers?backend=webservers&version=$CFGVER'

nix
CFGVER=$(curl -s -u admin:adminpwd http://localhost:5555/v2/services/haproxy/configuration/version)
curl -X POST \
  -u admin:adminpwd \
  -H "Content-Type: application/json" \
  -d '{"name":"anotherserver", "address":"127.0.0.1", "port":8080, "check":"enabled"}' \
  '127.0.0.1:5555/v2/services/haproxy/configuration/servers?backend=webservers&version=$CFGVER'

Commit the change by calling the commit action on the /services/git/actions API endpoint:

nix
curl -X POST \
  -u admin:adminpwd \
  -H 'Content-Type: application/json' \
  -d '{ "action":"commit", "commit_message":"add new web server" }' \
  '127.0.0.1:5555/v2/services/git/actions'

nix
curl -X POST \
  -u admin:adminpwd \
  -H 'Content-Type: application/json' \
  -d '{ "action":"commit", "commit_message":"add new web server" }' \
  '127.0.0.1:5555/v2/services/git/actions'

Then push the change to the remote repository by calling the push action:

nix
curl -X POST \
  -u admin:adminpwd \
  -H 'Content-Type: application/json' \
  -d '{ "action":"push" }' \
  '127.0.0.1:5555/v2/services/git/actions'

nix
curl -X POST \
  -u admin:adminpwd \
  -H 'Content-Type: application/json' \
  -d '{ "action":"push" }' \
  '127.0.0.1:5555/v2/services/git/actions'

You can also pull the latest changes from the remote repository by calling the pull action:

nix
curl -X POST \
  -u admin:adminpwd \
  -H 'Content-Type: application/json' \
  -d '{ "action":"pull" }' \
  '127.0.0.1:5555/v2/services/git/actions'

nix
curl -X POST \
  -u admin:adminpwd \
  -H 'Content-Type: application/json' \
  -d '{ "action":"pull" }' \
  '127.0.0.1:5555/v2/services/git/actions'
