I have tried using the following startup commands, and both successfully start the app as reported in the _default_docker.log but the app service is stopping the container because a HTTP ping for port 8080 doesn't get a response.
pm2 start ecosystem.config.js
pm2 start npm -- run serve:ssr 4000
ecosystem.config.js file - works fine locally and launching the web app successfully on port 8080, and I have uploaded the file to ./site/wwwroot/ folder in the app service.
module.exports = {
apps : [{
name: 'ssrapp',
script: './dist/server/',
instances: 1,
autorestart: true,
watch: false,
max_memory_restart: '2G'
}]
};

I have tried setting the following settings in the App Service Application Settings (documentation on these is hard to come by and contradicting) but they don't seem to make any difference:
PORT: 8080
WEBSITES_PORT: 8080
CONTAINER_AVAILABILITY_CHECK_MODE: ReportOnly
WEBSITES_CONTAINER_START_TIME_LIMIT: 1800
Note: the node app launches fine in App Service with the start-up command "npm run serve:ssr", but I want to launch it via pm2 to avail of the monitoring and restart features.
It looks like the App Service environment is stopping the container because it doesn't respond to the HTTP ping in under 5 seconds, but I can't find any way to disable this to confirm that is the actual issue.
Architect Jamie suggestion in the comment below solved the issue, the --no-daemon parameter was needed. Thank you!
