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:

  • 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=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]

From Collector Service

om <path> pull
