Inner loop on JayeX - Cloud Native CI/CD Built On Kubernetes

okteto

Mon, 01 Jan 0001 00:00:00 +0000

If you install okteto it has a command you can use to spin up a development container inside a deployment so you can iteratively rebuild an application.

Then if your application is deployed to your staging environment you can cd into a git clone of your application and run…

# switch to the staging namespace
jx ns jx-staging

okteto up

You will now have a development container setup you can perform incremental builds

ksync

Mon, 01 Jan 0001 00:00:00 +0000

You can use ksync to synchronise your local source code with a running pod which you can then use to perform incremental builds inside kubernetes.

kubectl run -ti --image maven maven-build-pod bash
ksync create -n jx --pod maven-build-pod $(pwd) /
ksync watch

# then in your build pod run `mvn clean install` or `mvn spring-boot:run` or whatever

skaffold

See the skaffold site on how to use skaffold to perform localy builds of a project.

Essentially you do the following:

install skaffold
cd into a git clone of your application
run

skaffold init

then to run your application

skaffold run --tail

localizer

Mon, 01 Jan 0001 00:00:00 +0000

localizer is a lightweight go lang based rewrite of telepresencse. See the blog for more detail

It basically lets you run local processes on your laptop right inside your IDE which are then connected into the kubernetes cluster via networking magic.

Using localizer

install localizer
run localizer:

sudo localizer

run/debug your application locally.
then to expose your service into a namespace as a service name run something like this::

localizer expose $namespace/$svc --map 80:8080

when you have finished debugging, return things to normal via:
