Installing an Edge as a Binary
The standalone edge is currently built from source. The source code is available in the PlakarKorp/plakar-edge repository.
Build it with:
$ make
# OR
$ go build -o plakar-edge .Enroll the edge
Start the edge with the Control Plane URL, enrollment key, and organization it should join:
$ plakar-edge \
-control-plane https://plakman.example.com \
-enroll <enrollment-key> \
-organization <organization-id> \
-name edge-paris-1 \
-state-dir /var/lib/plakar-edge \
-pkg /var/lib/plakar-edge/pkgsThe enrollment key and organization are only required for the first startup. After successful enrollment, the edge stores its identity and authentication token in its state directory and reuses them on subsequent starts.
For subsequent starts, you can therefore run:
$ plakar-edge \
-control-plane https://plakman.example.com \
-name edge-paris-1 \
-state-dir /var/lib/plakar-edge \
-pkg /var/lib/plakar-edge/pkgsConfiguring the edge
The most important options are:
| Option | Required | Description |
|---|---|---|
-control-plane |
Yes | Base URL of the Plakar Control Plane. |
-enroll |
First run | Enrollment key used to register the edge. It can also be provided through PLAKAR_EDGE_ENROLL_KEY. |
-organization |
First run | Identifier of the organization the edge joins. It can also be provided through PLAKAR_EDGE_ORGANIZATION. |
-name |
No | Name displayed for the edge in PCP. Defaults to the hostname. |
-state-dir |
No | Directory used to store the edge identity and authentication token. Defaults to /var/lib/plakar-edge. |
-pkg |
No | Directory used for downloaded connector packages. Defaults to <state-dir>/pkg. |
-max-parallel |
No | Maximum number of tasks the edge runs concurrently. Defaults to 5. |
-poll-hold |
No | Expected server-side long-poll duration. Defaults to 30s. |
-listen |
No | Address of the supervision HTTP server. Defaults to 127.0.0.1:9877. Set it to an empty string to disable the server. |
-metrics |
No | Enables the Prometheus /metrics endpoint. Defaults to true. |
-scripts-dir |
No | Directory holding the hook scripts tasks may run. Empty by default, which refuses every hook. |
-max-parallel caps how much work one edge takes on at a time. The Control
Plane does not assign an edge more tasks than this limit at once.
