[SOLVED] GC Deployment Manager install PHP with Jinja template

GC Deployment Manager install PHP with Jinja template

I want do deploy a PHP app via the Google Cloud Deployment Manager. After an instance has been created, PHP (and some other Linux packages) should be installed on the VM. Is this possible within the template file? Or do I have to create a custom VM image?

I only managed to create the VM, but didn't find anything on how to automatically install packages.

{% set COMPUTE_URL_BASE = 'https://www.googleapis.com/compute/v1/' %}
{% set BASE_NAME = env['deployment'] + '-' + env['name'] %}

{% macro GlobalComputeUrl(project, collection, name) -%}
{{ COMPUTE_URL_BASE }}projects/{{ project }}/global/{{ collection }}/{{ name }}
{%- endmacro %}

{% macro ZonalComputeUrl(project, zone, collection, name) -%}
{{ COMPUTE_URL_BASE }}projects/{{ project }}/zones/{{ zone }}/{{ collection }}/{{ name }}
{%- endmacro %}

resources:
- name: {{ BASE_NAME }}
  type: compute.v1.instance
  properties:
    zone: {{ properties['zone'] }}
    machineType: {{ ZonalComputeUrl(env['project'], properties['zone'], 'machineTypes', 'e2-micro') }}
    metadata:
      items:
        - key: gce-container-declaration
          value: |
            {{ imports[properties['containerManifest']]|indent(12) }}
    disks:
      - deviceName: boot
        type: PERSISTENT
        autoDelete: true
        boot: true
        initializeParams:
          diskName: {{ BASE_NAME }}-disk
          sourceImage: {{ GlobalComputeUrl('cos-cloud', 'images', properties['containerImage']) }}
    networkInterfaces:
      - accessConfigs:
          - name: external-nat
            type: ONE_TO_ONE_NAT
        network: {{ GlobalComputeUrl(env['project'],  'networks', 'default') }}
    serviceAccounts:
      - email: default

Solution

It is possible using DM, but... are you sure you want to run containers and at the same time install PHP on the host? If you're runnning containers, I'd rather add another container with PHP. It makes more sense.

Anyway, if you want to install PHP (and others) on host, you can use a metadata.startup-script (example here: https://github.com/GoogleCloudPlatform/deploymentmanager-samples/tree/master/examples/v2/metadata_from_file/jinja). As @fariya-rahmat mentioned - probably you want to use a different OS for it.
