PM2 embed a simple and powerful deployment system with revision tracing. It's based on https://github.com/visionmedia/deploy
A step-by-step tutorial is available here : Deploy and Iterate faster with PM2 deploy
Please read the Considerations to use PM2 deploy
1- Generate a sample ecosystem.json file that list processes and deployment environment
$ pm2 ecosystem
In the current folder a ecosystem.json
file will be created.
It contains this:
{
"apps" : [{
"name" : "API",
"script" : "app.js",
"env": {
"COMMON_VARIABLE": "true"
},
"env_production" : {
"NODE_ENV": "production"
}
},{
"name" : "WEB",
"script" : "web.js"
}],
"deploy" : {
"production" : {
"user" : "node",
"host" : "212.83.163.1",
"ref" : "origin/master",
"repo" : "[email protected]:repo.git",
"path" : "/var/www/production",
"post-deploy" : "pm2 startOrRestart ecosystem.json --env production"
},
"dev" : {
"user" : "node",
"host" : "212.83.163.1",
"ref" : "origin/master",
"repo" : "[email protected]:repo.git",
"path" : "/var/www/development",
"post-deploy" : "pm2 startOrRestart ecosystem.json --env dev",
"env" : {
"NODE_ENV": "dev"
}
}
}
}
Edit the file according to your needs.
2- Be sure that you have the public ssh key on your local machine
$ ssh-keygen -t rsa
$ ssh-copy-id [email protected]
3- Now initialize the remote folder with:
$ pm2 deploy <configuration_file> <environment> setup
E.g:
$ pm2 deploy ecosystem.json production setup
This command will create all the folders on your remote server.
4- Deploy your code
$ pm2 deploy ecosystem.json production
Now your code will be populated, installed and started with PM2
