ASAP: PM2 environment variables are identical on two different instances although the variables must be different

[ibudisteanu]

Hi,

For 4 hours I am struggling with pm2 and I encounter a bug. I wrote a script that opens multiple instances. Although all the instances have different environment variables, the apps receive the same identical environment variable namely the last one. Please kindly help me out because I need to deploy the pm2 on multiple xeon servers.

{
  "apps": [

    {
      "script": "npm",
      "name": "start8080",
      "args": "start",
      "env": {
        "SERVER_PORT": 8080,
        "INSTANCE_PREFIX": "8080",
        "NODE_ENV": "production"
      },
      "error_file": "logs/proj-8080.err.log",
      "out_file": "logs/proj-8080.out.log"
    },
    {
      "script": "npm",
      "name": "start80",
      "args": "start",
      "env": {
        "SERVER_PORT": 80,
        "INSTANCE_PREFIX": "80",
        "NODE_ENV": "production"
      },
      "error_file": "logs/proj-80.err.log",
      "out_file": "logs/proj-80.out.log"
    },

  ]
}

Both instances receive the last environment variable namely as value "80".

The data is passed to the application but only the last one. If I switch the apps between each other, and make the 8080 the last one, the apps receive the environment variable as "8080" on both instances.

I am using pm2 under Linux, Ubuntu 16.x, Debian

pm2 version 2.10.3

Thanks

I was able to make a trick to solve my problem, but still running the script has the same behavior as described above.

I was able to bypass the need of script by using the pm2 inline CLI

SERVER_PORT=80 INSTANCE_PREFIX=80 pm2 start  npm -- run start -- n=80 ;
pm2 restart npm --name "80" --update-env ;

SERVER_PORT=8080 INSTANCE_PREFIX=8080 pm2 start npm -- run start ;
pm2 restart npm --name "8080" --update-env ;

SERVER_PORT=8081 INSTANCE_PREFIX=8081 pm2 start npm -- run start ;
pm2 restart npm --name "8081" --update-env ;

SERVER_PORT=8082 INSTANCE_PREFIX=8082 pm2 start npm -- run start ;
pm2 restart npm --name "8082" --update-env ;

SERVER_PORT=8083 INSTANCE_PREFIX=8083 pm2 start npm -- run start ;
pm2 restart npm --name "8083" --update-env
