This project is as a PoC to setup a ipfs-cluster replica set or statefulset using Kubernetes. It should handle resizing of any type and be resilient to the various conditions both ipfs-cluster and kubernetes can find themselves in.
This project was inspired by and references https://github.com/cvallance/mongo-k8s-sidecar
This is pre-alpha software and should not be used in a production environment
Currently managing addition of new nodes to the cluster works.
Nodes are not currently removed from the cluster. (With a persistent store nodes will rejoin the cluster with their newly assigned IP). If not using a persistent store we will have to remove the node from the cluster.
The docker image is hosted on docker hub and can be found here: https://hub.docker.com/r/joshorig/ipfs-cluster-k8s-sidecar/
An example kubernetes statefulset can be found in the examples directory on github here: https://github.com/ConsenSys/ipfs-cluster-k8s-sidecar
There you will also find some helper scripts to test out creating the replica set and resizing it.
| Environment Variable | Required | Default | Description |
|---|---|---|---|
| KUBE_NAMESPACE | NO | The namespace to look up pods in. Not setting it will search for pods in all namespaces. | |
| IPFSCLUSTER_SIDECAR_POD_LABELS | YES | This should be a be a comma separated list of key values the same as the podTemplate labels. See above for example. | |
| IPFSCLUSTER_SIDECAR_SLEEP_SECONDS | NO | 5 | This is how long to sleep between work cycles. |
| IPFSCLUSTER_PORT | NO | 9094 | Configures the ipfs-cluster port, allows the usage of non-standard ports. |
- Add cluster removal
- Add SSL support
- Add tests!
- Add to travisCI
- Alter k8s call so that we don't have to filter in memory
