Create, Deploy¶
The following actions only modify files in <OSVCETC>. No operating system configuration file is modified, so they are safe to experiment with.
The agent support object creation via two commands:
createThe object is created but not provisioned nor started.deployThe 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=docker \
--kw container#0.image=ghcr.io/opensvc/pause \
--kw orchestrate=ha \
--kw nodes={clusternodes}
From Another Object¶
om <dst path> create --config=<src path>
From Manifest, Single Object¶
The manifest must be json formatted, structured like om <path> print config --format=json.
om <path> create --config=<manifest uri>
This method can also be used to clone objects
om <src path> print config --format json | \
om <dst path> create --config=- [--interactive] [--provision]
From Manifest, Multiple Objects¶
The manifest must be json formatted, structured like om <selector> print config --format=json.
In this case, the <dst path> can not be specified, but the destination namespace where to create the objects can. The new objects will adopt the names set in the manifest.
om svc create --namespace=newns --config=<manifest uri>
om 'test/svc/*' print config --format=json | \
om svc create --namespace=testclone --config=-
From Existing Local Configuration File¶
Experienced users may find it easier to start from a copy of the conf file of an existing similar object.
om <path> create --config <path to config file> [--interactive] [--provision]
The configuration file can be remote, referenced by URI.
From Collector Template¶
Templates can be served by the collector.
om <path> create --template <id|name> [--interactive] [--provision]
