Imagine we have Deployment Manager’s config file that creates a virtual machine from certain image and assigns an ephemeral public IP address to it. Something like this:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
resources: - name: tiny-vm type: compute.v1.instance properties: zone: us-central1-a machineType: zones/us-central1-a/machineTypes/f1-micro disks: - deviceName: boot type: PERSISTENT boot: true autoDelete: true initializeParams: sourceImage: projects/ubuntu-os-cloud/global/images/family/ubuntu-1804-lts networkInterfaces: - network: global/networks/default accessConfigs: - name: External NAT type: ONE_TO_ONE_NAT |
If I decided to create 5 other VMs, similar to this one, I’d probably have to copy-paste the config, changing just the tiny pieces: the name and probably the zone with the image.
However, Deployment manager supports Jinja and Python templates, so we can move a repetitive blocks into those, leaving only customizable parts on the surface. Let’s see is how it works for Python. Continue reading “Python templates in GCP Deployment Manager”
