Callback

Deployer object

The following object is passed to onXXXDeploy functions :

{
    // Current configuration
    options: { ... },
    
    // Current release name
    releaseTag: '2017-01-25-08-40-15-138-UTC',
    
    // Current release path on the remote server
    releasePath: '/opt/.../releases/2017-01-25-08-40-15-138-UTC',
    
    // Use this function to execute some commands on the remote server
    execRemote: [Function: execRemote] 
}

Example with onXXXDeploy

onBeforeDeploy, onBeforeLink, onAfterDeploy options.

You have to call callback function to continue deployment process.

onAfterDeploy: (deployer, callback) => {
    const command = 'pwd';
    const showLog = false;
    deployer.execRemote(command, showLog, callback);
}

Example with onXXXDeployExecute

onBeforeDeployExecute, onBeforeLinkExecute, onAfterDeployExecute options.

onAfterDeployExecute: [
    'do something on the remote server',
    'and another thing'
]

Or with a function :

onAfterDeployExecute: (deployer) => {
    grunt.log.subhead('Doing something');
    return [
        'do something on the remote server',
        'and another thing'
    ];
}

onBeforeDeploy

Function called before deployment. Call callback to continue;

Type: function(deployer, callback)

onBeforeDeployExecute

Array (or function returning array) of commands to execute on the remote server.

Type: function(deployer) | []

onBeforeLink

Function called before symlink creation. Call callback to continue;

Type: function(deployer, callback)

onBeforeLinkExecute

Array (or function returning array) of commands to execute on the remote server.

Type: function(deployer) | []

onAfterDeploy

Function called after deployment. Call callback to continue;

Type: function(deployer, callback)

onAfterDeployExecute

Array (or function returning array) of commands to execute on the remote server.

Type: function(deployer) | []

Examples

Restart Apache after deployment

grunt.config.set('ssh-deploy-release', {
    options: {
        localPath: 'public',
    },
    
    production: {
        options: {
            host: 'hostname',
            username: 'username',
            password: 'password',
            deployPath: '/opt/path/to'
        }
    },
    
    onAfterDeployExecute: (deployer) => {
        grunt.log.subhead('Restart php-fpm and apache');
        return [
            'sudo /opt/bitnami/ctlscript.sh restart apache'
        ];
    }
});

Dynamic environments

For example, create one environement by git branch.

grunt.config.set('ssh-deploy-release', {
    options: {
        localPath: 'public',
    },
    
    review: {
        options: {
            host: 'hostname',
            username: 'username',
            password: 'password',
            deployPath: '/opt/path/to/' + grunt.option('branch'),
            allowRemove: true
        }
    },
});

Deploy a branch

grunt ssh-deploy-release:review --branch="BRANCH_NAME"

Remove a branch on the remote server

grunt ssh-deploy-release:review --branch="BRANCH_NAME" --remove

In order to avoid mistakes (remove production..), allowRemove must be true to remove release on the remote server

Plug it with Gitlab CI to deploy review app

Example of .gitlab-ci.yml :

 Deploy review:
    stage: deploy
    except:
     - preproduction
     - production
    environment:
      name: review/$CI_BUILD_REF_SLUG
      url: http://host/$CI_BUILD_REF_SLUG/www/
      on_stop: stop_review
    script:
     - yarn
     - grunt ssh-deploy-release:review --branch="$CI_BUILD_REF_SLUG"


  stop_review:
    stage: deploy
    script:
     - yarn
     - grunt ssh-deploy-release:review --branch="$CI_BUILD_REF_SLUG" --remove
    when: manual
    variables:
      GIT_STRATEGY: none
    except:
     - preproduction
     - production
    environment:
      name: review/$CI_BUILD_REF_SLUG
      action: stop
