Alert Manager Container Crash

[hollowpnt92]

I found an issue with the alertmanager-deployment.yaml when using the most up to date prometheus.

If anyone else sees this, the pod will deploy and then you will see the following. See fix section if you need to fix this.

This is fixed for me, just wanted to leave this for awareness.

# FIX

They have changed the syntax of the deployment file to require a "--" in the specified area, the syntax of the spec heading should be as follows in the "alertmanager-deployment.yaml" file.

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: alertmanager
spec:
replicas: 1
selector:
matchLabels:
app: alertmanager
template:
metadata:
name: alertmanager
labels:
app: alertmanager
spec:
containers:
- name: alertmanager
image: prom/alertmanager:master
args:
- '--config.file=/etc/alertmanager/config.yml'
- '--storage.path=/alertmanager'
- '--web.external-url=$(EXTERNAL_URL)/alertmanager'
