Project and Directory Structure

• We are using the suggested directory structure provided by the Ansible community: https://docs.ansible.com/ansible/latest/user_guide/playbooks_best_practices.html#directory-layout

To Do:

1. Research ssh pipelining issue, currently turned off across entire playbook, slow.
2. Install Cloudwatch agent and configure.
3. Setup SSH Access, currently using bfd-jenkins key. Located in team keybase.

1. Figure out why task Configure File Provider Plugin in conf_jenkins fails with: script failed with stacktrace: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:\nScript1.groovy: 121: unable to resolve class org.jenkinsci.plugins.configfiles.maven.MavenSettingsConfig \n @ line 121, column 3.\n new org.jenkinsci.plugins.configfiles.maven.MavenSettingsConfig(\n ^\n\nScript1.groovy: 135: unable to resolve class org.jenkinsci.plugins.configfiles.maven.MavenToolchainsConfig \n @ line 135, column 3.\n new org.jenkinsci.plugins.configfiles.maven.MavenToolchainsConfig

        • Device: /dev/sdf
        • Filesystem: xfs
  • Build the Jenkins AMI (first time) From within the Ansible/ directory of the ops code (i.e. bfd-ops) run the following command to build AND configure the Jenkins instance and volume for the first time.
    • packer build -var 'source_ami=<insert_gold_ami_id>' -var 'subnet_id=subnet-036f17fe18e59a0d9' build_jenkins.json
  • Note the AMI ID that was created and Update the terraform vars for Jenkins deployment with the new AMI.
