GCE Setup Instructions

Get a gce service key

1. ask your GCE project administrator for a GCE service key

Note: If your GCE project does not show a Service Account under /APIs & auth/Credentials, you will need to use "Create new Client ID" to create a Service Account.

Convert a GCE service key into a pem (for ansible)

1. mkdir -p ~/.gce
2. The gce service key looks something like this: projectname-ef83bd90f2.p12 .. the ef83bd90f2 part is the public hash
3. Be in the same directory as the p12 key file.
4. The commands below should be copy / paste-able

5. Run these commands: ```

   Temporarily set hash variable

   export GCE_KEY_HASH=ef83bd90f2

# Convert the service key (note: 'notasecret' is literally what we want here) openssl pkcs12 -in projectname-${GCE_KEY_HASH}.p12 -passin pass:notasecret -nodes -nocerts | openssl rsa -out projectname-${GCE_KEY_HASH}.pem

# Move the converted service key to the .gce dir mv projectname-${GCE_KEY_HASH}.pem ~/.gce

# Set a sym link so it is easy to reference ln -s ~/.gce/projectname-${GCE_KEY_HASH}.pem ~/.gce/projectname_priv_key.pem

1. Once this is done, put the original service key file (projectname-ef83bd90f261.p12) somewhere safe, or delete it (your call, I don not know what else we will use it for, and we can always regen it if needed).


Create a gce.ini file for GCE
--------------------------------
1. vi ~/.gce/gce.ini
1. make the contents look like this:

[gce] gce_service_account_email_address = long...@developer.gserviceaccount.com gce_service_account_pem_file_path = /full/path/to/projectname_priv_key.pem gce_project_id = my_project_id

1. Setup a sym link so that gce.py will pick it up (link must be in same dir as gce.py)

cd openshift-online-ansible/inventory/gce ln -s ~/.gce/gce.ini gce.ini

Install Dependencies
--------------------
1. Ansible requires libcloud for gce operations:

yum install -y ansible python-libcloud

Test The Setup
--------------
1. cd li-ops/cloud
2. Try to list all instances:

./cloud.rb gce list

3. Try to create an instance:

./cloud.rb gce launch -n ${USER}-minion1 -e int --type os3-minion ```
