🔨 Add devcontainer

[cyw3]

Provide a develop enviroment docker container.

Developers can use it and don't need to deploy the build environment again.

hi @cyw3, thanks for your contribution! as it stands, this pr does not contain enough information to be merged since Docker workflows is not something the dev team has discussed as far as i remember. there are a number of questions which pop up immediately like the choice of the base image and the JDK distribution. if you think this should be included, please make the case for it in more detail, either here or on the Discord channel.

What @ursachec said. Thank you for sharing, but we have a few questions.
It would be good to get a better description of the use case, ideally in the readme, e.g. in a development section.

The base image is almost 1g, comes from a vendor and ships their jdk:

[root@cf01afb1383b TencentKona-11.0.15.b1]# bin/java -version
openjdk version "11.0.15-ga" 2022-04-28
OpenJDK Runtime Environment TencentKonaJDK (build 11.0.15-ga+1)
OpenJDK 64-Bit Server VM TencentKonaJDK (build 11.0.15-ga+1, mixed mode)

I don't know much about them, but can't we just use a more common/standard and/or small image like openjdk or some alpine linux?

@ursachec

It is easy to deploy the build environment with devcontainer and VSCode extension remote - container. And developers don't need to care about the build environment again and can immediately focus on their dev work.

Compared to such benefits, the cost of the choice of the base image and the JDK distribution is relatively small.

TencentOS and TencentKona are just the software I use more often.

If you have a better recommendation, I can try to modify it here.

Are the following two satisfied?

• centos:centos7.9.2009
• openjdk-11.0.1

[mpollmeier]

yes, centos and/or openjdk sound good

[cyw3]

Ok, I update the devcontainer with them now.

[mpollmeier]

Thank you! Now would you mind adding a few words on how to use it, e.g. in the readme? That'll also give it visibility to others.

DONE

[mpollmeier]

Thank you! I'll merge this as is and will add a section on Intellij, which is the IDE most of our team use. Good to get an overview and instructions for different dev setups.

[cyw3]

done

[mpollmeier]

thanks @cyw3
