Autostarting NodeJS Apps

You can have all of your NodeJS applications spin up automtically as soon as you docker-compose up. This can be achieved by makeing use of (Node.js Process Manager) and the autostart feature.

Read more about how to add scripts for autostart commands:

custom_scripts_per_php_version (individually for different PHP versions)
custom_scripts_globally (equal for all PHP versions)

Self-built

Simply add a script ending by .sh to the autostart/ directory that will accomplish this. The following example will make use of to spin up your NodeJS application.

Assumption

Path to your NodeJS project (within the Docker container): /shared/httpd/my-node/src
Name of the JS file to startup: index.js

The script

Add the following script to autostart/

su -c "cd /shared/httpd/my-node/src; pm2 start index.js" -l devilbox

The whole command is wrapped into su to ensure the application will be started as the user devilbox.
cd tells it to you enter the directory where index.js can be found
And finally will take care about starting up your javascript file.

Once the Devilbox is running, you can enter the PHP container and verify with pm2 list that everything is running as expected.

Pre-built

Instead of writing multiple scripts for multiple applications, you can also make use of the pre-shipped script that allows you to start unlimitted NodeJS applications via .

The following script is provided in autostart/run-node-js-projects.sh-example and needs to be copied to a file ending by .sh

host> cd /path/to/devilbox
host> cd autostart
host> cp run-node-js-projects.sh-example run-node-js-projects.sh

In that newly created file, you can simply add the full paths (path inside the Docker containre) of your Javascript files that need to be started. There is already one example which is not commented. Change this to your path and add as many lines as you have projects to startup.

../../autostart/run-node-js-projects.sh-example

Reverse proxy NodeJS

If you also want to know how to reverse proxy your NodeJS service and have it available via the web server including HTTPS support have a look at the following links:

reverse_proxy_with_https
example_setup_reverse_proxy_nodejs

Imagine you have started an application within the PHP container that creates a listening port (e.g.: NodeJS). This will now only listen on the PHP container and you would have to adjust the docker-compose.yml definition in order to have that port available outside to your host OS.

Alternatively, there is a simple way to reverse proxy it to the already running web server and even make use of the already available HTTPS feature.
