Your environment needs to have some tools. You can verify that you have them by running ./check_dependencies.sh. It will say "All good." if your environment has everything that's needed.

1. Go into the AWS management console. Take note of the AWS region you're in. You need to create three things.

• An SSH keypair. Download the ".pem" file for this keypair and save it to this directory as ec2_key.pem. Run chmod 400 ec2_key.pem in order to set the access permissions on it correctly.
• A security group. Get the identifier for this security group.
• A subnet. Get the identifier for this subnet.

For everything mentioned above, you need to update the appropriate variable value in terraform.tfvars.

2. Decide on your jenkins login credentials and put them into a file called "jenkins_creds.txt" in the format username:password. For example, you could run echo "jenkins:superpassword" > jenkins_creds.txt to create this file with a user 'jenkins', with password 'superpassword'.

Some of this is flaky, so sometimes you might have to rerun a script or two.

• Provision everything with terraform apply & take it down with terraform destroy. You can also use ./node_bounce.sh.
• Set up Jenkins on the EC2 instance with ./node_bootstrap.sh.
• Download the Jenkins CLI tool from the new Jenkins server using ./jenkins_cli_download.sh.
• Create the initial Jenkins user according to the credentials in jenkins_creds.txt by using ./jenkins_create_user.py
• Run ./jenkins_install_plugins.sh to install the required Jenkins plugins.
• Once Jenkins has installed all the plugins, go to the update center (jenkins_install_plugins.sh will print out a link to it at the start of script execution). Check the box at the bottom which says it'll make Jenkins restart. This should then immediately cause Jenkins to begin restarting. The restart should not take long at all. Certainly under a minute.
• Once Jenkins finished restarting, it should direct you to the login screen. Use the credentials you configured earlier to log in. You'll now finish the installation as described below.
• When asked which plugins to install, choose "Choose my own plugins". Choose 'none' (there's a button near the top to select none if necessary) and then press the button to proceed.
• When asked about the Jenkins URL, continue with the default value.
• After that, you should be able to start using Jenkins normally.

• SSH into the machine with ./node_ssh.sh.
• Set up a global pipeline library using ./jenkins_create_library.py <library repository url>.
• Open Jenkins in the browser using ./jenkins_open_in_browser.sh.
