Jib and Helm

Helm установлен

// Проверка, что проект билдится
// Нет необходимости выполнять
$ ./mvnw package

$ vi pom.xml

Прописываю подходящую версию библиотеки jib-maven-plugin

<groupId>com.google.cloud.tools</groupId>
<artifactId>jib-maven-plugin</artifactId>
<version>3.4.0</version>

Если протухнет, смотреть здесь:

https://github.com/GoogleContainerTools/jib/tree/master/jib-maven-plugin#quickstart

$ skaffold run --profile jibWithHelm

$ skaffold delete --profile jibWithHelm

Kustomize

$ skaffold dev

$ skaffold run --profile=kustomizeBase --default-repo=gcr.io/basic-curve-316617
$ skaffold run --profile=kustomizeProd --default-repo=gcr.io/basic-curve-316617

$ skaffold delete

$ skaffold run --profile=kustomizeDev

$ echo $PROFILE
marley-minikube
$ eval $(minikube -p ${PROFILE} docker-env)

Fail!
