prerequisite
- Docker
- Docker Compose
- Maven
- Kubernetes Cluster
- Docker Hub Account
local testing
Run mvn clean package
Then run java -jar target/hello-springboot-0.0.1-SNAPSHOT.jar
Now Spring boot application is running locally, Verify it by hitting the below URL
http://localhost:8080/api/hello
First, you need to give the following variable value in the config.yml file
Docker
docker-hub-email: <>
docker-hub-username: <>
docker-hub-password: <>
docker-hub-repo-name: <>
Kubernetes
server: <>
namespace: <>
cad: <>
token: <>
then save the file on local, Don't push it to the repository and you can also use vault as a secret manager.
-
Download the Docker compose file
`wget https://concourse-ci.org/docker-compose.yml` -
Run the Docker Compose File
`docker-compose up -d` -
Download the fy CLI tool from the localhost:8080
-
Give execute permission to the fly CLI
`chmod +x fly` -
Copy the fly CLI to the /usr/bin
`sudo cp fly /usr/bin/` -
Login to the concourse
`fly -t tutorial login -c http://localhost:8080 -u test -p test` -
Clone the following spring boot project
`git clone https://github.com/azmathasan92/concourse-ci-cd.git` -
Change to the root dir of the project
`cd concourse-ci-cd` -
Create Concourse Pipeline
`fly -t tutorial set-pipeline -p spring-boot-service -c concourse_ci/pipeline.yml -l concourse_ci/config.yml` -
Unpause Concourse Pipeline
`fly -t tutorial unpause-pipeline -p spring-boot-service`
Now you have successfully setup the CI/CD pipeline that test, package and deploy your project to the Kubernetes.
