William Markito Oliveira commented on GEODE-60:
-----------------------------------------------
We may be discussing a couple different things here...
1) The size of the openjdk8 docker image in my machine is about 800MB, which is
exactly the reason I did the Java install as part of the Geode Dockerfile.
2) If we reuse that part and use it as a base for our image, it end up with
350MB. Just Centos + JDK - unnecessary stuff. No Geode.
3) In my understanding, if you are going to automate the build process with
Docker and in order to not rely on the hosting system at all even volumes may
not be good, hence I was thinking we would also clone and build Geode source
inside Docker. But I'm not a build expert and using volumes would work as well
or I may be wrong... Don't know.
4) In any case, there is a Docker image that will be available to Geode users
that will of course have Geode on it. That's what the Dockerfile in the docker
folder of Geode produces. Which then adds the remaining bytes to the final
size of 490MB. We could do much better if the final version was just using
JRE and maybe a smaller OS than Centos.
Size is important in order to allow people that will pass around and distribute
the docker images or build applications with multiple containers that may also
need to download those images on different hosts. This problem may not apply
here to our build process.
The other reason for creating our own base image is that, as [~jaoki] pointed,
Oracle is still not really into Docker and their images may change or be
removed and that would break our build. So I'd vote for creating our own.
Sizing on my box:
{code}
$ docker images
REPOSITORY TAG IMAGE ID

The Dockerfile with Java 8 and without cloning and building Geode would look
like this:
{code}

>
> geode build is on gradle and seems very tidy but it still requires third
> party libraries, like Java.
> Let's have a Docker environment so that at least we have an reliable
> immutable environment and we can use it on CI on builds.apache.org
> https://builds.apache.org/view/E-G/view/Geode/
> (From my experience, It is a bit of pain to find a right environment on
> builds.a.o but Docker is a cure so far.)
