Adding nodes to an existing clusterΒΆ
In the existing cluster profile, add
host
lines to specify the additional node(s).EXAMPLE: You have this existing cluster profile,
~/.continuum/adam/profile.d/profile.yaml
:name: profile provider: bare bare: username: centos # password: password # Optional port: 22 keypair: ~/.ssh/my-private-key nodes: - host: node1.company.com - host: node2.company.com - host: node3.company.com - host: node4.company.com
You want to add the following nodes:
- node10.company.com
- node11.company.com
- node12.company.com
Assuming these nodes use the same authentication mode as the existing nodes, add a
host
line for each node:name: profile provider: bare bare: username: centos # password: password # Optional port: 22 keypair: ~/.ssh/my-private-key nodes: - host: node1.company.com - host: node2.company.com - host: node3.company.com - host: node4.company.com - host: node10.company.com - host: node11.company.com - host: node12.company.com
Run the
adam up
command to provision the cluster.EXAMPLE: To use the profile named “profile” to provision the cluster named “cluster”, run:
$ adam up -n cluster profile
You are prompted to overwrite the cluster definition file located at
~/.continuum/adam/cluster.d/cluster.yaml
to include the newly defined nodes.During the provisioning process, Adam will install on the new nodes and will not reinstall on the previously defined nodes.
