stack72 / jenkins-setup Goto Github PK

##Prerequisites:

• Packer
• Terraform

These can be installed using homebrew if you have it as follows:

brew tap unofficial-cask/hashicorp-tap [email protected]:unofficial-cask/hashicorp-tap.git

brew install packer

brew install terraform

The latest versions of each is fine.

##Running Instructions:

Set AWS Access Keys for use:

export AWS_ACCESS_KEY_ID=<my access key>
export AWS_SECRET_ACCESS_KEY=<my secret access key>

To Build the AMI for use in Terraform:

cd packer/
make ami

That will build an ami named ubuntu-jenkins-master-<date> in us-west-2

To build the environment:

cd ../terraform
make ssh-key
make plan

That should give an output ending:

Plan: 16 to add, 0 to change, 0 to destroy.

Then apply the changes if correct:

make apply

The output should look as follows (ignore the yellow text in Terraform 0.7.9 - that's an experimental feature we run in the backgroud that has no bearing on your infra!)

Apply complete! Resources: 16 added, 0 changed, 0 destroyed.

We print the Jenkins Address to the output. Take that address and put it into the browser and you will see a message that looks as follows:

To ensure Jenkins is securely set up by the administrator, a password has been written to the log (not sure where to find it?) and this file on the server:

To get the key, use the terminal output jenkins_ssh_instructions

e.g.

ssh -i ssh/jenkins [email protected]
sudo cat /var/lib/jenkins/secrets/initialAdminPassword

Put that password into the screen et voila!
