I'm trying to debug a PHP app running on Docker with VSCode, but without success.
In the past I was able to easily debug my PHP apps with VSCode running WAMP Server, but since I started working with Docker I'm unable to get debug working. Searched for several tutorials online, checked some threads here on StackOverflow (ex.: Docker and XDebug not reading breakpoints VSCode), but I'm still not able to get this working.
Dockerfile:

When I debug the app no breakpoint is being triggered. What am I doing wrong?
UPDATE: Based on some suggestions i've updated my docker-compose.yml and my launch.json files but nothing changed.
docker-compose.yml
ports:
- 18080:80
- 14430:443
- 9000:9000 //added new xdebug default port
launch.json
"configurations": [
{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"pathMappings": {
"/srv/app/cms": "${workspaceRoot}/my.app/cms",
},
"port": 9000,
"log": true
}
]
VSCode Debug Console:
<- launchResponse
Response {
seq: 0,
type: 'response',
request_seq: 2,
command: 'launch',
success: true }
UPDATE #2: Removed the Xdebug port (9000) from the docker-compose.yml settings. Here is the xdebug log result:

Any more suggestions?
UPDATE #3: Solved my issue using the following settings:
launch.json
