Adding new scriptworker instances of an existing type¶
We don’t yet have a scriptworker provisioner, so spinning up new instances of a specific type is still a manual process that can definitely use improvement. Here are docs on how to spin a new instance up.
If this is a chain of trust enabled scriptworker, you’ll need to generate a gpg keypair. Otherwise (dev or dep scriptworker), skip to the next step.
Generate and sign a gpg keypair for user@fqdn, per these docs.
The pubkey will need to land in the cot-gpg-keys repo, in the
scriptworker/valid directory. The keypair will need to go into puppet hiera, as specified below.
For a signing scriptworker instance, find a valid signing-range IP and add to dns, like the slave loan. These will be in similar subnets to the existing instances:
10.134.30.12 signing-linux-1.srv.releng.use1.mozilla.com 10.132.30.46 signing-linux-2.srv.releng.usw2.mozilla.com 10.134.30.125 signing-linux-3.srv.releng.use1.mozilla.com 10.132.30.82 signing-linux-4.srv.releng.usw2.mozilla.com
Go to the EC2 console, go to the appropriate region (usw2, use1).
- Instances -> Launch Instance -> My AMIs ->
- t2-micro -> configure instance details
- change the subnet to the
signingsubnet; add a public IP; specify the DNS IP at the bottom -> Add storage
- General purpose SSD -> Tag Instance
- Tag with its name, e.g. signing-linux-5 -> Configure security group
- Select an existing group; choose the
signing-workergroup; review and launch
- make sure to choose a keypair you have access to, e.g. aws-releng or generate your own keypair. Puppet will overwrite this.
If this is a chain of trust enabled scriptworker, add the gpg keypair into hiera. This will be the
scriptworker_gpg_public_keys dictionaries. The dictionary key is the instance fqdn; the value is the encrypted file.
ssh into the instance as root, using the ssh keypair you specified above.
# first, edit /etc/yum-local.cfg to replace `puppetagain.*/data/` with `releng-puppet2.srv.releng.mdc1.mozilla.com` yum -c /etc/yum-local.cfg install puppet
Then puppetize (you need the deploy pass for this):
# change the hostname so the cert matches hostname FQDN # grab puppetize.sh and run it wget https://hg.mozilla.org/build/puppet/raw-file/tip/modules/puppet/files/puppetize.sh # if we're doing a standard puppetize PUPPET_SERVER=releng-puppet2.srv.releng.mdc1.mozilla.com sh puppetize.sh # if we want to puppetize against an environment PUPPET_SERVER=releng-puppet2.srv.releng.mdc1.mozilla.com PUPPET_EXTRA_OPTIONS="--environment=USER" sh puppetize.sh # run puppet puppet agent --test
It is probably best to reboot after puppetizing. After this point, it should Just Work.
