Run from maven, without docker, for development

[mihnita]

With this one can execute mvn package cargo:run and it will download a tomcat version (in target/), deploy, and run.

No need to run build-docker.sh, which takes extra time, and creates a new docker image.
These docker images accumulate, take disk space, and need to be deleted once in a while.

You also don't need to have Docker installed.

Does this mean it runs locally, or on the server?

[mihnita]

This is for testing / debugging locally.
It starts a Tomcat server locally and deploys the .war there.
So you connect to http://localhost:8080

The current process builds the war, builds a Docker image with Tomcat and the war in it, runs the image in Docker, and you connect to http://localhost:8080

So both options run locally, but this one

• is just one Maven command
• less disk space (the Docker images accumulate and need to be deleted once in a while)
• faster: does not build a docker image, and startup time is faster (instead of starting a docker image then start Tomcat in it, this just starts Tomcat)
• less memory
• no need to install docker (some companies have restrictions on installing it on work computers)

The Docker way is still there and still works.
In the readme I still recommend a final test with the Docker image because that's how we deploy it in the cloud.

[mihnita]

It can do a lot more.
For example start a server, then deploy new .war files there without restarting.

See

Or connect an ide for debugging:

Very likely also possible with the Docker approach, with a bit more tinkering.

which was the reason for this… originally it was a local tomcat deploy.

Yeah. Considering https://unicode-org.atlassian.net/browse/CLDR-19389 for CLDR survey tool for similar reasons.
