# MongoDB Helm Chart
|
||||
|
||||
## Prerequisites Details
|
||||
* Kubernetes 1.3 or higher with alpha APIs enabled.
|
||||
* Petsets are in alpha in 1.3.
|
||||
* Init containers are alpha in 1.3 and are moving to beta in 1.4.
|
||||
* PV support on the underlying infrastructure.
|
||||
|
||||
## PetSet Details
|
||||
* http://kubernetes.io/docs/user-guide/petset/
|
||||
|
||||
## PetSet Caveats
|
||||
* http://kubernetes.io/docs/user-guide/petset/#alpha-limitations
|
||||
|
||||
# TODO
|
||||
* Set up authorization between replicaset peers.
|
||||
* Add a liveliness check.
|
||||
* Make the `test.sh` script more robust.
|
||||
|
||||
## Chart Details
|
||||
|
||||
This chart implements a dynamically scalable [mongoDB replica set](https://docs.mongodb.com/manual/tutorial/deploy-replica-set/)
|
||||
using Kubernetes PetSets and Init Containers.
|
||||
|
||||
## Get this chart
|
||||
|
||||
Download the latest release of the chart from the [releases](../../../releases) page.
|
||||
|
||||
Alternatively, clone the repo if you wish to use the development snapshot:
|
||||
|
||||
```console
|
||||
$ git clone https://github.com/kubernetes/charts.git
|
||||
```
|
||||
|
||||
## Installing the Chart
|
||||
|
||||
To install the chart with the release name `my-release`:
|
||||
|
||||
```console
|
||||
$ helm install --name my-release mongodb-x.x.x.tgz
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
The following tables lists the configurable parameters of the mongodb chart and their default values.
|
||||
|
||||
| Parameter | Description | Default |
|
||||
|-----------------------|----------------------------------|----------------------------------------------------------|
|
||||
| `Name` | Name of the chart | `mongodb` |
|
||||
| `Image` | Container image name | `mongo` |
|
||||
| `ImageTag` | Container image tag | `3.2` |
|
||||
| `ImagePullPolicy` | Container pull policy | `Always` |
|
||||
| `Replicas` | k8s petset replicas | `3` |
|
||||
| `Component` | k8s selector key | `mongodb` |
|
||||
| `Cpu` | container requested cpu | `100m` |
|
||||
| `Memory` |container requested memory | `512Mi` |
|
||||
| `PeerPort`| Container listening port | `27017` |
|
||||
| `Storage`| Persistent volume size | `10Gi` |
|
||||
|
||||
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`.
|
||||
|
||||
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
|
||||
|
||||
```console
|
||||
$ helm install --name my-release -f values.yaml mongodb-x.x.x.tgz
|
||||
```
|
||||
|
||||
> **Tip**: You can use the default [values.yaml](values.yaml)
|
||||
|
||||
Once you have all 3 nodes in running, you can run the "test.sh" script in this directory, which will insert a key into the primary and check the secondaries for output. This script requires that the `$RELEASE_NAME` environment variable be set, in order to access the pods.
|
||||
|
||||
# Deep dive
|
||||
|
||||
Because the pod names are dependent on the name chosen for it, the following examples use the
|
||||
environment variable `RELEASENAME`. For example, if the helm release name is `messy-hydra`, one would need to set the following before proceeding. The example scripts below assume 3 pods only.
|
||||
|
||||
```console
|
||||
export RELEASE_NAME=messy-hydra
|
||||
```
|
||||
|
||||
## Cluster Health
|
||||
|
||||
```console
|
||||
$ for i in 0 1 2; do kubectl exec $RELEASE_NAME-mongodb-$i -- sh -c '/usr/bin/mongo --eval="printjson(db.serverStatus())"'; done
|
||||
```
|
||||
|
||||
## Failover
|
||||
|
||||
One can check the roles being played by each node by using the following:
|
||||
```console
|
||||
$ for i in 0 1 2; do kubectl exec $RELEASE_NAME-mongodb-$i -- sh -c '/usr/bin/mongo --eval="printjson(rs.isMaster())"'; done
|
||||
|
||||
MongoDB shell version: 3.2.9
|
||||
connecting to: test
|
||||
{
|
||||
"hosts" : [
|
||||
"messy-hydra-mongodb-0.messy-hydra-mongodb.default.svc.cluster.local:27017",
|
||||
"messy-hydra-mongodb-1.messy-hydra-mongodb.default.svc.cluster.local:27017",
|
||||
"messy-hydra-mongodb-2.messy-hydra-mongodb.default.svc.cluster.local:27017"
|
||||
],
|
||||
"setName" : "rs0",
|
||||
"setVersion" : 3,
|
||||
"ismaster" : true,
|
||||
"secondary" : false,
|
||||
"primary" : "messy-hydra-mongodb-0.messy-hydra-mongodb.default.svc.cluster.local:27017",
|
||||
"me" : "messy-hydra-mongodb-0.messy-hydra-mongodb.default.svc.cluster.local:27017",
|
||||
"electionId" : ObjectId("7fffffff0000000000000001"),
|
||||
"maxBsonObjectSize" : 16777216,
|
||||
"maxMessageSizeBytes" : 48000000,
|
||||
"maxWriteBatchSize" : 1000,
|
||||
"localTime" : ISODate("2016-09-13T01:10:12.680Z"),
|
||||
"maxWireVersion" : 4,
|
||||
"minWireVersion" : 0,
|
||||
"ok" : 1
|
||||
}
|
||||
|
||||
|
||||
```
|
||||
This lets us see which member is primary.
|
||||
|
||||
Let us now test persistence and failover. First, we insert a key (in the below example, we assume pod 0 is the master):
|
||||
```console
|
||||
$ kubectl exec $RELEASE_NAME-mongodb-0 -- /usr/bin/mongo --eval="printjson(db.test.insert({key1: 'value1'}))"
|
||||
|
||||
MongoDB shell version: 3.2.8
|
||||
connecting to: test
|
||||
{ "nInserted" : 1 }
|
||||
```
|
||||
|
||||
Watch existing members:
|
||||
```console
|
||||
$ kubectl run --attach bbox --image=mongo:3.2 --restart=Never -- sh -c 'while true; do for i in 0 1 2; do echo <$release-podname-$i> $(mongo --host=$RELEASE_NAME-mongodb-$i.$RELEASE_NAME-mongodb --eval="printjson(rs.isMaster())" | grep primary); sleep 1; done; done';
|
||||
|
||||
Waiting for pod default/bbox2 to be running, status is Pending, pod ready: false
|
||||
If you don't see a command prompt, try pressing enter.
|
||||
messy-hydra-mongodb-2 "primary" : "messy-hydra-mongodb-0.messy-hydra-mongodb.default.svc.cluster.local:27017",
|
||||
messy-hydra-mongodb-0 "primary" : "messy-hydra-mongodb-0.messy-hydra-mongodb.default.svc.cluster.local:27017",
|
||||
messy-hydra-mongodb-1 "primary" : "messy-hydra-mongodb-0.messy-hydra-mongodb.default.svc.cluster.local:27017",
|
||||
messy-hydra-mongodb-2 "primary" : "messy-hydra-mongodb-0.messy-hydra-mongodb.default.svc.cluster.local:27017",
|
||||
messy-hydra-mongodb-0 "primary" : "messy-hydra-mongodb-0.messy-hydra-mongodb.default.svc.cluster.local:27017",
|
||||
|
||||
```
|
||||
|
||||
Kill the primary and watch as a new master getting elected.
|
||||
```console
|
||||
$ kubectl delete pod $RELEASE_NAME-mongodb-0
|
||||
|
||||
pod "messy-hydra-mongodb-0" deleted
|
||||
```
|
||||
|
||||
Delete all pods and let the petset controller bring it up.
|
||||
```console
|
||||
$ kubectl delete po -l app=mongodb
|
||||
$ kubectl get po --watch-only

$ kubectl exec $RELEASE_NAME-mongodb-1 -- /usr/bin/mongo --eval="rs.slaveOk(); db.test.find({key1:{\$exists:true}}).forEach(printjson)"
|
||||
|
||||
MongoDB shell version: 3.2.8
|
||||
connecting to: test
|
||||
{ "_id" : ObjectId("57b180b1a7311d08f2bfb617"), "key1" : "value1" }
|
||||
```
|
||||
|
||||
## Scaling
|
||||
|
||||
Scaling should be managed by `helm upgrade`, which is the recommended way.
|
||||
You can also scale up by modifying the number of replicas on the PetSet using `kubectl patch` or `kubectl apply`. Deleting the various pods created and the associated resources needs some care and is described in the [petset documentation](http://kubernetes.io/docs/user-guide/petset/#deleting-a-pet-set).

Getting Started:

1. After the petset is created completely, one can check which instance is primary by running:
|
||||
$ for i in `seq 0 2`; do kubectl exec {{ printf "%s-%s" .Release.Name .Values.Name | trunc 24 }}-$i -- sh -c '/usr/bin/mongo --eval="printjson(rs.isMaster())"'; done.
|
||||
This assumes 3 replicas, 0 through 2. It should be modified to reflect the actual number of replicas specified.
|
||||
|
||||
2. One can insert a key into the primary instance of the mongodb replica set by running the following:
|
||||
$ kubectl exec MASTER_POD_NAME -- /usr/bin/mongo --eval="printjson(db.test.insert({key1: 'value1'}))"
|
||||
MASTER_POD_NAME must be replaced with the name of the master found from the previous step.
|
||||
|
||||
3. One can fetch the keys stored in the primary or any of the slave nodes in the following manner.
|
||||
$ kubectl exec POD_NAME -- /usr/bin/mongo --eval="rs.slaveOk(); db.test.find().forEach(printjson)"
|
||||
POD_NAME must be replaced by the name of the pod being queried.
