This application is used for demo a simple usecase using CRC with microshift preset.
$ crc config set preset microshift
$ crc setup
$ crc start
$ crc status
CRC VM: Running
RAM Usage: 1.182GB of 3.759GB
Disk Usage: 3.469GB of 8.579GB (Inside the CRC VM)
Cache Usage: 135GB
Cache Directory: /Users/prkumar/.crc/cache
This repo have Containerfile which can be used to generate the container image
for this application and we can directly use podman socket which is exposed by CRC
$ eval $(crc podman-env --root)
$ podman build -t quay.io/praveenkumar/myserver:v1 -f Containerfile .
$ podman run -d -p 8080:8080 quay.io/praveenkumar/myserver:v1
$ curl localhost:8080
hello
Now everything works locally and we also created the image, next step would be try to deploy it on the cluster and see if our app still work.
$ eval $(crc oc-env)
$ export KUBECONFIG=${HOME}/.crc/machines/crc/kubeconfig
$ oc apply -f kubernetes/deploy.yaml
$ oc get pods -n demo
