The Problem

Client said their portainer was really slow. It cannot opened anything.

When change menu, it takes forever to load.

So they ask, is there any alternative? They only need app to check their cluster log and re-scale service

Here’s Come Swarmpit

Swarmpit introduce themself as a “Lightweight mobile-friendly Docker Swarm management UI”, and they really prove that.

It more simple, fast and robust than Portainer.

It fullfill my client criteria, it can show app log and you can re-scale services from there

It Show All Info and It was Faster Than Portainer

Common Issues

Common issues at Swarmpit installation

Request execution failed! Scope at influxDB log. Solution, since it can find any influxDB server, please use constraint it will make influxDB installed on specific server. This problem solution applied to Swarmpit and CouchDB service as well
It not showing hardware specification web page. Solution, make sure you opened all swarm mode port
