We are deploying with Ansible scripts to Openshift 3 using oc apply. When we change template to add more environment variables, we receive a very vague error: "unrecognized type: string" and status code 500.
Setting --loglevel 10 leads to no more details:
$ /usr/local/bin/oc_v3.11.715 apply -f \"/tmp/ansible.YtEqVm_deploy/app.yml.json\" -n test-env --loglevel 10 2&> log.log
(several GET to get secret, deploymentconfigs, etc.)

F0127 11:49:05.466618 605 helpers.go:119] Error from server: unrecognized type: string
The request body is like:
{
"metadata": {
"annotations": {
"kubectl.kubernetes.io/last-applied-configuration": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}
},
"spec": {
"template": {
"spec": {
"$setElementOrder/containers": [{
"name": "app"
}],
"containers": [{
"$setElementOrder/env": [{
"name": "OLD_VAR_1"
}, {
"name": "OLD_VAR_2"
}, {
"name": "OLD_VAR_3"
}, {
"name": "OLD_VAR_4"
}, {
"name": "NEW_VAR_1"
}, {
"name": "NEW_VAR_2"
}, {
"name": "NEW_VAR_3"
}],
"dnsPolicy": "ClusterFirst",
"env": [{
"name": "OLD_VAR_4",
"value": false
}, {
"name": "NEW_VAR_1",
"value": 10
}, {
"name": "NEW_VAR_2",
"value": 20
}, {
"name": "NEW_VAR_3",
"value": 6
}],
"name": "app",
"restartPolicy": "Always",
"terminationGracePeriodSeconds": 300
}]
}
}
}
}
OLD_VAR_x are old environment variables; we want to add NEW_VAR_[1-3]. Notice strangely that not all old vars are in env, only OLD_VAR_4, but all new vars are in env.
This also happens when we use oc patch with the same request body. Same error response.
What is wrong?
A workaround is first, deployment, fail, and add new vars in Openshift manually, and deploy in Openshift webconsole on top of the last, failed deployment. It works.
Solved by quoting the var values in the template, like:
- name: NEW_VAR_X
value: "${NEW_VAR_VALUE_X}"
No errors ever since.
