Hi
I’m having troubles adding a metadata key/value where the value is a multiline string when provisioning with the gce module. I just can’t get it to work from Ansible, I get the error: bad metadata: malformed string. If I do it in the command
The background is this Docker preview in GCE: https://developers.google.com/compute/docs/containers
If I provision a GCE machine manually I can se the --metadata-from-file flag to load a whole YAML file into a value. The content ends up in the key google-container-manifest.
If I provision manually using the command:
gcloud compute instances create containervm-test-1 \
–image projects/google-containers/global/images/container-vm-v20140522 \
–metadata-from-file google-container-manifest=containers.yaml \
–zone us-central1-a \
–machine-type f1-micro
It looks like this in the prompt for metadata:
metadata:
fingerprint: n5JL5z74Ofk=
items:
- key: google-container-manifest
value: "version: v1beta1\ncontainers:\n - name: simple-echo\n image: google/busybox\n\
\ command: [‘nc’, ‘-p’, ‘8080’, ‘-l’, ‘-l’, ‘-e’, ‘echo’, ‘hello world!’]\n\
\ ports:\n - name: nc-echo\n hostPort: 8080\n containerPort:\
\ 8080"
My Ansible variable looks like this:
vars:
manifest: |
version: v1beta1
containers:
- name: repository
image: google/docker-registry
ports:- name: registry
containerPort: 5000
env:- key: GCS_BUCKET
value: mlwr-docker-registry- name: client
image: localhost:5000/data-loader
volumeMounts:- name: data
path: /mnt/data- name: server
image: localhost:5000/data-server
ports:- name: www
containerPort: 80
volumeMounts:- name: data
path: /mnt/data
volumes:- name: data
Used like this:
gce_metadata: ‘{“google-container-manifest”: “{{ manifest }}”}’
I have tried all combinations I could come up with, but it seems that something goes wrong with the data before yaml parsing and literal_eval in the GCE Ansible-module. I tried to reproduce in a python console but it seemed to work fine.
Thanks
