KNetraHub IP Management worker: background jobs only, no HTTP endpoint.
750
IP Management worker ā the background half of IP Management.
KNetraHub is a self-hosted IT operations portal: a Docker Swarm console, full-stack monitoring, work management, privileged access management, IP address management and a database workspace, behind one sign-in. It ships two ways ā as a single monolith image, or as the split stack of one image per service that this image belongs to.
š Documentation: https://sengphirum.github.io/KNetraHub/documentationā
IPAM subnet scans (ICMP) and utilisation alerts ā cluster-leased singletons.
It bundles the server code of ipmgt and nothing else, so the image carries only the module it is named after.
Runs no HTTP listener at all. It claims work from a durable queue with FOR UPDATE SKIP LOCKED and, for the jobs that must run once cluster-wide, a lease that one replica holds at a time ā so replicas cooperate instead of duplicating. On SIGTERM it stops claiming, finishes what it already holds and hands the rest back to the queue, which is why its stop_grace_period is generous.
The ingress never routes to it and it answers no request. Losing it delays work; it does not fail a page load.
Every service in the split stack runs unprivileged with cap_drop: [ALL]. This one additionally needs NET_RAW, because it sends ICMP echo itself.
| Image | Serves HTTP | Runs background jobs | Scale it with |
|---|---|---|---|
knetrahub-ipmgt-worker (this image) | no | yes | job volume |
knetrahub-ipmgt-apiā | yes | no | request load |
knetrahub-appā | yes | yes | nothing ā it is one process |
Scale this with job volume. The matching ipmgt-api image handles the requests, and the two scale on completely different signals.
Read straight from the stack file that deploys this service, so the list is what the image actually takes. Optional entries ship commented out.

NUXT_DB_POOL_MAX | 6 | set |
NUXT_MODULE_POOL_REPLICAS | 2 | set |
NUXT_JWT_SECRET | change-me-to-a-long-random-string | set |
NUXT_ENV_MODE | staging | optional |
NUXT_DB_HOST | timescaledb | set |
NUXT_DB_PORT | 5432 | set |
NUXT_DB_NAME | knetrahub | set |
NUXT_DB_USER | knetrahub | set |
NUXT_DB_PASSWORD | change-me-to-a-long-random-string | set |
KNETRA_INTERNAL_TOKEN_FILE | /run/secrets/knetrahub_internal_token | optional |
NUXT_IPMGT_SCAN_ENABLED | false | optional |
NUXT_IPMGT_SCAN_INTERVAL_SECONDS | 300 | optional |
Anything ending in _FILE reads its value from that path instead, which is how the stack passes Docker secrets.
This is one service of a stack, not a standalone container: it expects the portal database and its siblings on the same overlay network. Deploy it with the stack file that owns it rather than with docker run.
docker stack deploy -c docker/docker-compose.yml knetrahub
Pin a tag or a registry for this one service with KNETRAHUB_IPMGT_WORKER_IMAGE, which the stack file reads:
export KNETRAHUB_IPMGT_WORKER_IMAGE=phirumseng/knetrahub-ipmgt-worker:0.1.11
latest ā the most recent releasex.y.z (e.g. 0.1.11) ā immutable release versionsPin the version in production. A rollback needs a tag that does not move, and every image in the stack is released under the same version so the whole set can be pinned together.
Each service is its own image, so one can be updated without restarting the others:
