- When creating a new CJE cluster that uses internal VPC, the cluster-init operation fails with error relating to access to Mesos
Error querying mesos metrics at http://mesos.xr-jenkins-controller-239852362.us-east-1.elb.amazonaws.com.elb.cloudbees.net/metrics/snapshot: <urlopen error timed out> Mesos failed to start after 40 attempts. There were one or more errors
- CloudBees Jenkins Enterprise (1.x versions on AWS)
When installing CJE to an internal VPC on AWS there are several items you must provide in the cluster-init.config
vpc_id : ID of the existing VPC vpc_subnet_id : ID of the existing subnet additional_security_group_id : ID of an existing security group ID that will be added to all instances and elb of the cluster. internal : must be set to yes
Errors or misconfigurations associated with these values can cause the verifications to fail and then fail the init operation.
See addtional detail on internal VPCs and refrence architecture in this section of the CJE admin guide
