* Single node as a StatefulSet in k8s - uses bigchaindb/bigchaindb:0.9.1 * Updating README * rdb, mdb as stateful services * [WIP] bdb as a statefulset * [WIP] bdb w/ rdb and bdb w/ mdb backends - does not work as of now * Split mdb & bdb into separate pods + enhancements * discovery of the mongodb service by the bdb pod by using dns name. * using separate storage classes to map 2 different volumes exposed by the mongo docker container; one for /data/db (dbPath) and the other for /data/configdb (configDB). * using the `persistentVolumeReclaimPolicy: Retain` in k8s pvc. However, this seems to be unsupported in Azure and the disks still show a reclaim policy of `delete`. * mongodb container runs the `mongod` process as user `mongodb` and group `mongodb. The corresponding `uid` and `gid` for the `mongod` process is 999 and 999 respectively. When the constinaer runs on a host with a mounted disk, the writes fail, when there is no user with uid 999. To avoid this, I use the docker provided feature of --cap-add=FOWNER in k8s. This bypasses the uid and gid permission checks during writes and allows writes. Ref: https://docs.docker.com/engine/reference/run/#runtime-privilege-and-linux-capabilities * Delete redundant k8s files, add cluster deletion steps. * Single node as a StatefulSet in k8s - uses bigchaindb/bigchaindb:0.9.1 * Updating README * rdb, mdb as stateful services * [WIP] bdb as a statefulset * [WIP] bdb w/ rdb and bdb w/ mdb backends - does not work as of now * Split mdb & bdb into separate pods + enhancements * discovery of the mongodb service by the bdb pod by using dns name. * using separate storage classes to map 2 different volumes exposed by the mongo docker container; one for /data/db (dbPath) and the other for /data/configdb (configDB). * using the `persistentVolumeReclaimPolicy: Retain` in k8s pvc.
