Steps to build and deploy the service on kubernetes

[pranay-garg-groww]

Hey,
I am able to build the services with the following command :
cd backend && mvn -f pom-first.xml install && cd .. && mvn -T4C -DskipTests clean install
but not able to create the Docker image from all the individual jars. I understand that you use jib plugin for creating docker images but I cannot find the command to run that.
Can you guyz pls send a step by step commands for setting up a kubernets pipeline for building and deploying the service.

We are evaluating featurehub for a company wide use case at large scale and need some assistance. It would be really helpful if we can get on a call and understand some internal setup of the service.

Thanks

Hey there! We don't recommend you build the code unless you are intending to contribute functionality. If you would like to use k8s, please feel free to use the helm chart https://github.com/featurehub-io/featurehub-helm, there is space in the helm chart values for you to add you appropriate Cloud Vendor's required customisations to expose the service. There is also a kind local installation guide for you to run it on k8s locally so you can see how it fits together.

If you would like to follow the Architecture - please have a look at our Architecture diagrams in our documentation and feel free to ask questions here.

Hey, thanks for the reply.
I actually intend to contribute functionality and play around with some changes. Can you please share the details of how to build the code to a docker image?

[rvowles]

Sure! If you are planning on building a docker image just to the local docker engine, there is a script in the backend folder called build.sh - if you run that then it builds the appropriate docker images into your local machine. If you have a registry that you have access to and wish to push the images there automatically, then the release.sh script in the same folder does this, but you will need to set the environment variable OVERRIDE_DOCKER_PREFIX to specify your repository and prefix. Its just featurehub by default at the moment and pushes to Dockerhub and our featurehub account. But it will build multi-architecture images.

The front end is built using Flutter, but it does use a docker image to do so, which is on Dockerhub so you should be fine doing that.

So the command you listed which builds all of the code into your local repo, and then the build.sh or release.sh script builds the images. Note, there are no Dockerfiles in any of the front ends because Jib takes care of all of that (user space docker image building).

got it,
while running the file I am getting the following error

Heya - this is presumably because you are running on an Apple Silicon Mac and it doesn't emulate a AMD64 architecture for certain key areas. You will need to build the image for the flutter-web docker image for Apple Silicon yourself unfortunately, we are all on Intel silicon, and our build servers are all Intel as well. The image is in the folder pipeline/build/flutter_web - if you are building locally you can just use the script as is - just docker image rm the existing image on your machine. There is a script there that will build the requisite image and the debian base is multi-architecture.

I've removed the image and when running the make-image.sh I am getting the following error

Hey again! I'm back from xmas/new years break, did you resolve this?
