Create, Deploy

The following actions only modify files in /etc/opensvc. No operating system configuration file is modified, so they are safe to experiment with.

The agent support object creation via two commands:

• create The object is created but not provisioned nor started.

• deploy The object is created, provisioned and started.

Both actions support the same arguments. The following examples use only create commands.

From Scratch, non Interactive

Create a new object with minimal configuration. No resources are described.

om <path> create

Resources and default keywords can be set right from the create command, using --kw <keyword>=<value> options

om <path> create \
	--kw container#0.type=oci \
	--kw orchestrate=ha \
	--kw nodes={clusternodes}

Scripts should describe the object as completely as possible in this single command. The keywords given to create are part of the first and only commit, so the object is never announced to the cluster in a half-configured state. Creating a bare object then completing it with a series of config update commands publishes every intermediate state to the peers, and the orchestrator acts on them as soon as orchestrate is set.

From Another Object

om <dst path> create --config=<src path>

From Manifest

The manifest must be ini formatted, like the output of om <path> config show.

om <path> create --config=<manifest uri>

This method can also be used to clone objects

om <dst path> create --config=<src path>

or

om <src path> config show | om <dst path> create --config=-
