Local Development

Requirements

  • Golang version higher than 1.13;

NOTE: The GOPATH and GOROOT environment variables should be added in PATH.

export GOPATH=C:\Users\<<username>>\go
export GOROOT=C:\Go

Operator Launch

In order to run the operator, follow the steps below:

  1. Clone repository;

  2. Open folder in GoLand Intellij IDEA, click the add_config_button button and select the Go Build option: add_configuration

  3. In Configuration tab, fill in the following:

    3.1. In the Field field, indicate the path to the main.go file;

    3.2. In the Working directory field, indicate the path to the operator;

    3.3. In the Environment field, specify the platform name (OpenShift/Kubernetes); build-config

  4. Run 'go build main.go' (Shift+F10);

  5. Check the operator logs in output console:

{"level":"info","ts":1580910952.5723817,"logger":"cmd","msg":"Go Version: go1.13.7"}
{"level":"info","ts":1580910952.5723817,"logger":"cmd","msg":"Go OS/Arch: windows/amd64"}
{"level":"info","ts":1580910952.573358,"logger":"cmd","msg":"Version of operator-sdk: v0.8.0+git"}
{"level":"info","ts":1580910952.5762863,"logger":"leader","msg":"Trying to become the leader."}
{"level":"info","ts":1580910952.5762863,"logger":"leader","msg":"Skipping leader election; not running in a cluster."}
{"level":"info","ts":1580910954.8339577,"logger":"cmd","msg":"Registering Components."}
{"level":"info","ts":1580910956.9645422,"logger":"kubebuilder.controller","msg":"Starting EventSource","controller":"keycloak-controller","source":"kind source: /, Kind="}

Exceptional Cases

CASE 1

After starting the Go build process, the following error will appear:

go: finding github.com/openshift/api v3.9.0
go: finding github.com/openshift/client-go v3.9.0
go: errors parsing go.mod:
C:\Users\<<username>>\Desktop\EDP\edp-admin-console\go.mod:36: require github.com/openshift/api: version "v3.9.0" invalid: unknown revision v3.9.0

Compilation finished with exit code 1

To resolve the issue, update the go dependency by applying the Golang command:

go get github.com/openshift/api@v3.9.0
CASE 2

If you get the Unauthorized error in logs, check the current KUBECONFIG path. Before running the operator in the Go build configuration (see point 4), you can specify another KUBECONFIG path:

WATCH_NAMESPACE=test-deploy-platform;PLATFORM_TYPE=openshift;KUBECONFIG=C:\Users\<<username>>\.kube\kubeconfig
