To build a CI/CD pipeline for micro services applications with either blue/green deployment and develop Continuous Integration steps that include typographical checking (aka "linting").
This project shows skills of the following;
- Working in AWS
- Using Jenkins to implement Continuous Integration and Continuous Deployment
- Building pipelines
- Working with CloudFormation to deploy clusters
- Building Kubernetes clusters
- Building Docker containers in pipelines
- Blueocean on Jenkins
Can be found in <loadbalancer_domain:port>
To collect information on loadbalancer domain:port, run sudo kubectl describe service on jenkins machine.
-
First visit this medium page if you are running a blue green deployment to make sure you have configured all that is required.
-
For "sudo: no tty present and no askpass program" error, this is generally a permissions error when accessing jenkins machine,
- Safe measure is to write certain commands that you would like to escape asking for password in Jenkinsfile with the
sudo -nas opposed tosudo.
An otherwise unsafe method as it will not require password for ALL commands from the jenkins user,
- edit sudoers file
sudo nano /etc/sudoersor gedit. - add
jenkins ALL=(ALL) NOPASSWD: ALLunder the section "# Allow members of group sudo to execute any command"
- For "error: no context exists with the name:". This is most likely because your jenkins user does not have permissions to access context files. I updated file Jenkins machine file to switch to jenkins user earlier in kubectl configurations. However, for this error, on the jenkins machine;
- switch user to jenkins
sudo -su jenkins(this is the user you are logged into from jenkins UI) - run aws configure
aws configure - enable kubectl to run with jenkins user
sudo chmod u+x /kubectl/./kubectl - then update kubeconfig
aws eks --region <region> update-kubeconfig --name <clustername> - test that blueocean will be able to access context with the jenkins user
kubectl config use-context <context> - lastly, as an extra measure, add sudo to kubectl commands in Jenkinsfile.
