- CRUD Spring Boot Example
- Prerequisites
- Deploying application on OpenShift using Dekorate
- Deploying application on OpenShift using Helm
- Deploying application on Kubernetes using Helm
- Running Tests on OpenShift using Dekorate
- Running Tests on OpenShift using S2i from Source
- Running Tests on OpenShift using Helm
- Running Tests on Kubernetes with Helm
- JDK 11+ installed with JAVA_HOME configured appropriately
Before deploying the application using Dekorate, make sure you have deployed the database first:
oc create -f .openshiftio/database.yaml
⚠️ If you are using OCP 4.6 use the.openshiftio/database-4.6.yamlfile instead.
Once the database is up and running, we can deploy the application using Dekorate:
mvn clean verify -Popenshift -Ddekorate.deploy=trueTo deploy the application using a specific Spring Boot version use the -Dspring-boot.version switch.
mvn clean verify -Popenshift -Ddekorate.deploy=true -Dspring-boot.version=2.6.7First, make sure you have installed the Helm command line and connected/logged to a kubernetes cluster.
Then, you need to install the example by doing:
helm install crud ./helm --set app.route.expose=true --set app.s2i.source.repo=https://github.com/snowdrop/crud-example --set app.s2i.source.ref=<branch-to-use>
note: Replace <branch-to-use> with one branch from https://github.com/snowdrop/crud-example/branches/all.
And to uninstall the chart, execute:
helm uninstall crud
Requirements:
- Have installed the Helm command line
- Have connected/logged to a kubernetes cluster
You need to install the example by doing:
helm install crud ./helm --set app.ingress.host=<your k8s domain>
And to uninstall the chart, execute:
helm uninstall crud
./run_tests_with_dekorate_in_ocp.sh
⚠️ If you are using OCP 4.6 applying the--ocp-database-file ".openshiftio/database-4.6.yaml"parameter.
Alternatively, tests can be executed against a specific Spring Boot or Dekorate version by passing the
version as a -D<variable property name>=value parameter. For instance overriding both the Spring Boot and the Dekorate versions using their corresponding version properties is done the following way:
./run_tests_with_dekorate_in_ocp.sh -Dspring-boot.version=2.7.3 -Ddekorate.version=2.11.1./run_tests_with_s2i.sh
⚠️ If you are using OCP 4.6 apply the--ocp-database-file=".openshiftio/database-4.6.yaml"parameter.
This script can take the following parameters:
--repository-url: repository to use to source the images from--branch-to-test: branch to use to source the images from--maven-settings: custom maven settings file--ocp-database-file: custom databaseyamlfile (e.g.--ocp-database-file ".openshiftio/database-4.6.yaml")
./run_tests_with_s2i.sh --repository-url "https://github.com/snowdrop/crud-example" \
--branch-to-test branch-to-test \
--maven-settings "${HOME}/.m2/my-custom-maven-settings.xml" \
--ocp-database-file ".openshiftio/database-4.6.yaml"./run_tests_with_helm_in_ocp.sh
This script can take 2 parameters referring to the repository and the branch to use to source the images from.
./run_tests_with_helm_in_ocp.sh "https://github.com/snowdrop/crud-example" branch-to-testFirst, you need to create the k8s namespace:
kubectl create namespace <the k8s namespace>
Then, run the tests by specifying the container registry and the kubernetes namespace:
./run_tests_with_helm_in_k8s.sh <your container registry: for example "quay.io/user"> <the k8s namespace>
For example:
./run_tests_with_helm_in_k8s.sh "quay.io/user" "myNamespace"
