Resin (now Balena Cloud) is good but relatively bare bones at the moment. Issues we ran into:
- PagerDuty integration of device up/down (had to build our own similar to [1])
- Pinning specific devices to not latest version (not possible)
- Pinning specific devices to branch (not possible)
- Incremental / gradual / staged deployments (supposedly API has support for this but missing from standard tooling)
- Semantic versioning of releases (not possible, it only accepts and shows git SHA256)
- SSH access is technically possible (we reverse engineered their CLI tool which connects to their SSH reverse proxy) but it would be nicer if the resin ssh command provided a way to run remote commands non-interactively (e.g. to scrape load average, etc.).
- No prebuilt instrumentation like load average, memory usage, etc.
