It significantly reduces downtime of the stages. - I rebuilt Nomad Cluster to make it more flexible and clear. It becomes more easily to control existing stages - I designed and created monitoring (Prometheus + exporters (elk, oracle, node, nomad) + Grafana + Alertmanager) and logging (Filebeat + Opensearch stack) systems - I created some Jenkins pipelines with Groovy: - Scan for vulnerabilities with Trivy and Docker-Bench-Security - Setup servers and databases with Ansible Plugin - Improved some pipelines for Continous Deployment - Created Nomad jobs for PROD and documentation for it - Designed PROD logging system and calculated resources needed for it Show less
