Build Strategies

For disconnected installations

In disconnected all the images needed should be in the internal registry

Push the images needed to the internal registry (**This operation should be done on a machine whose cpu architecture matches the one where the cluster is running. For ex: if the cluster is on ppc64le, download the images on a power machine and push it to the cluster internal registry)

If you are using podman on your local laptop

podman login 

Docker Build

Create the project

oc new-project build-strategies

Create Imagestream

oc apply -f imagestream.yaml

Buildconfig with docker strategy

oc apply -f buildconfig-dockerbuild.yaml
oc start-build build-bc

Create the deployment, service & router

oc apply -f deployment.yaml
oc apply -f service.yaml
oc apply -f route.yaml

Test the deployed application

curl "http://$(oc get routes build-rt -o jsonpath='{.spec.host}')/basicop/add?n1=100&n2=200"

Cleanup the deployes application

oc delete -f route.yaml
oc delete -f service.yaml
oc delete -f deployment.yaml
oc delete -f buildconfig-binarybuild.yaml
oc delete -f imagestream.yaml

Binary Build

Create the project

oc new-project build-strategies

Create Imagestream

oc apply -f imagestream.yaml

Binary build - Buildconfig with binary strategy

oc apply -f buildconfig-binarybuild.yaml
oc start-build build-bc --from-dir=../apps/Simple-SpringBoot-App/

Create the deployment, service & router

oc apply -f deployment.yaml
oc apply -f service.yaml
oc apply -f route.yaml

Test the deployed application

curl "http://$(oc get routes build-rt -o jsonpath='{.spec.host}')/basicop/add?n1=100&n2=200"

Cleanup the deployes application

oc delete -f route.yaml
oc delete -f service.yaml
oc delete -f deployment.yaml
oc delete -f buildconfig-binarybuild.yaml
oc delete -f imagestream.yaml

Binary Build - For a disconnection installation without internet connection

Create the project

oc new-project build-strategies

Push the images needed to the internal registry (**This operation should be done on a machine whose cpu architecture matches the one where the cluster is running. For ex: if the cluster is on ppc64le, download the images on a power machine and push it to the cluster internal registry)
