Paulo Motta commented on CASSANDRA-18035:
-----------------------------------------
Thanks everyone for reviews and feedback!
In order to make local docker-based development easier to use, I wrapped local
docker setup tasks in the following ant targets:
*
[docker-build|https://github.com/pauloricardomg/cassandra/blob/CASSANDRA-18035/build.xml#L1994]:
Builds a local cassandra-test docker image
** Fails if docker does not exist or is not running.
*
[docker-start|https://github.com/pauloricardomg/cassandra/blob/CASSANDRA-18035/build.xml#L2033]:
Starts a local cassandra-test docker container
** Fails if docker does not exist or is not running.
** Fails if image is not built.
** Fails if container is already running.
*
[docker-stop|https://github.com/pauloricardomg/cassandra/blob/CASSANDRA-18035/build.xml#L2048]:
Stops a local cassandra-test docker container
** Fails if docker does not exist or is not running.
** Fails if docker if container is not running.
[~mshuler] can you check if these new ant targets are working for you?
In order to prevent the cassandra-test image from being (mis)used from outside
these ant tasks, I've placed the Dockerfile templates in the hidden
[.build/docker|https://github.com/pauloricardomg/cassandra/tree/CASSANDRA-18035/.build/docker]
directory, since this Dockerfile is intended for local development testing
only.
In order to avoid fragmenting documentation into multiple files, I've placed
the [Quick Start Development
Guide|https://github.com/pauloricardomg/cassandra/tree/CASSANDRA-18035#quick-start-development-guide]
into the project's main
[README|https://github.com/pauloricardomg/cassandra/tree/CASSANDRA-18035#readme]
file instead of the original approach of having additional QUICKSTART.md file
- I think this is acceptable since the quick start development guide is pretty
small.
While we have detailed instructions in the [Contributing to
Cassandra|https://cassandra.apache.org/_/development/index.html] section of the
website, the idea is to ship some basic environment setup and validation
instructions in the project README so users can get easily started when
cloning/forking the project.
If anyone is interested in reviewing, a rendered version of the proposed "Quick
Start Development Guide" can be found in
[https://github.com/pauloricardomg/cassandra/tree/CASSANDRA-18035#quick-start-development-guide].
I have pointed out in the new guide that more detailed contributor instructions
can be found in the [Contributing to
Cassandra|https://cassandra.apache.org/_/development/index.html] section of the
website.
I have created a [cassandra-website
PR|https://github.com/apache/cassandra-website/pull/195] to add a reference to
the new [Quick Start Development
Guide|https://github.com/pauloricardomg/cassandra/tree/CASSANDRA-18035#quick-start-development-guide]
in the [Contributing to Cassandra
|https://cassandra.apache.org/_/development/index.html]section of the website.
Does this work [~jmckenzie] ?
> Add "Hello World" docker-based quick start development guide
> ------------------------------------------------------------
>
> Key: CASSANDRA-18035
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18035
> Project: Cassandra
> Issue Type: Task
> Reporter: Paulo Motta
> Priority: Normal
> Time Spent: 40m
> Remaining Estimate: 0h
>
> I propose adding a new {{QUICKSTART.md}} guide that provides instructions to
> beginner contributors on how to:
> a) Setup a development environment and IDE from scratch on WSL/Ubuntu/Debian
> environments
> b) Run a simple unit test from the IDE
> c) Create a simple patch that prints "Hello World" during Cassandra
> initialization
> d) Test the patch on a local docker instance
> A new {{docker/}} directory is added along with the guide with the following
> utilities:
> a) Dockerfile: unoptimized vanilla docker image manifest suitable only for
> local dev testing.
> b) build.sh: build a cassandra artifact and cassandra-test image.
> c) start.sh: start local cassandra-test container.
> d) stop.sh: stop local-cassandra test container.
> A couple of follow-up improvements that come to mind:
> - Add ant targets to build/start/stop cassandra-test container.
> - Add OSX instructions.
> - More IDE setup instructions (ie. Eclipse/VScode).
> - A more involved Hello World example, perhaps creating a dummy VirtualTable
> with unit/dtests.
> - Update Dockerfile to point to build/ instead of creating an artifact.
> A DEV mailing list message was sent to gather community feedback on this
> proposal: https://lists.apache.org/thread/gmb0q5yb2bzbs0cjw7mlcz1vwk2l23g2
