Lazy Apache CloudStack in Docker for Demo and Tests

[davift]

Hey folks,

I managed to build and run ACS 4.20 TLS on Docker for the sake of a disposable and on-the-go test environment.

Lazy CloudStack

Very basic stuff. Feel free to give it a try!

Help Wanted

On the other hand, it does not work when I replace 4.20 with 4.21 or 4.22: https://github.com/davift/lazy-cloudstack/blob/main/Dockerfile

Encountered error:

2026-01-29 12:36:01,955 DEBUG [c.c.u.d.DbProperties] (main:[]) (logid:) DB properties were already loaded
<removed for brevity>
2026-01-29 12:36:07,308 WARN  [c.c.u.d.T.Transaction] (main:[]) (logid:) Unable to load db configuration, using defaults with 5 connections. Falling back on assumed datasource on localhost:3306 using username:password=cloud:cloud. Please check your configuration com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

While the Docker image above will run Ubuntu with Systemd, as ACS is designed to run, I also created a Docker Compose build with one container for MySQL and another for ACS Management that runs the Java binary directly (no need for Systemd): https://github.com/davift/lazy-cloudstack/blob/main/docker-compose/

Encountered error:

acs.local  | 2026-01-29 13:38:59,677 main ERROR TcpSocketManager (TCP:localhost:4560) caught exception and will continue: java.io.IOException: Unable to create socket for localhost at port 4560 using ip address 127.0.0.1 and port 4560

If anybody wants to collaborate, please let me know...
