How to run as background process

If you turn off the Auto-off feature, the container will remain running even if you close the workspace, but processes running in the terminal will be terminated. To prevent this, you need to run the process as a background process.

There are 2 options to set-up;

• Run in the background setting (recommended!)

• Use nohup command

Run in the background setting

Enter the execution command in the script, then tap the Run in the background checkbox to run the command.

command tap → Run → click right on wanted run command → setting → check Run in the background → Save and run.

Use nohup command

How to run

1

If the file to be run in the background process is a.out, you can run it as a background process by entering the following command in the terminal.

# nohup <absolute path>/ filename &

2

You can check for execution with the command below.

 # ps -aux | grep a.out

How to end

After finding the PID value with the ps command, end the process with the kill command.

# ps -ef | grep a.out
# kill -TERM PID number

Note nohup command automatically creates a file called nohup.out.

This file records the output of the commands you run with nohup.

If you don't want to create this file, you can have it output to /dev/null.

# nohup echo hello > /dev/null

If you are using node app

You can simply run it as a background process using the forever command in the npm package.

1

Install forever

$ npm install -g forever

2

Run the app with the command below

$ forever start app.js

3

You can verify whether it's running or not with the command below.

$ forever list

For detailed usage, please refer to forever usage.

An app that uses npm start

You can run the command set in scripts.start of package.json using npm start, but with PM2, you can run it more easily as a background application.

1

Install pm2

$ npm install -g pm2

2

Run the app with the command below

$ pm2 start npm -- start

3

You can verify whether it's running or not with the command below.

$ pm2 status
