Following example will use pharmer to create a Kubernetes cluster with 1 worker nodes and 3 master nodes (i,e, 4 nodes in your cluster) on AWS
As a prerequisite, you need to have pharmer installed. To install pharmer use the setup guide
To store your cluster and credential resource, you can configure pharmer to use local file system or postgres database. In this document we will use local file system (vfs) as a storage provider. To know more click here
You can create a credential named aws by running
$ pharmer create credential aws
Follow this guide for more information here
While creating cluster within AWS pharmer creates following IAM roles and policies
* IAM master policy
* IAM controller policy
* IAM master role
* IAM node policy
* IAM node role
There are two steps to create a Kubernetes cluster using pharmer. In first step pharmer create basic configuration file with user choice. Then in second step pharmer applies those information to create cluster on specific provider.
Here, we discuss how to use pharmer to create a Kubernetes cluster on aws
We want to create a cluster with following information:
For location code and sku details click hrere
Available options in pharmer to create a cluster are:
$ pharmer create cluster -h
Create a Kubernetes cluster for a given cloud provider
Usage:
pharmer create cluster [flags]
Aliases:
cluster, clusters, Cluster
Examples:
pharmer create cluster demo-cluster
Flags:
--credential-uid string Use preconfigured cloud credential uid
-h, --help help for cluster
--kubernetes-version string Kubernetes version
--masters int Number of masters (default 1)
--namespace string Namespace (default "default")
--network-provider string Name of CNI plugin. Available options: calico, flannel, kubenet, weavenet (default "calico")
--nodes stringToInt Node set configuration (default [])
-o, --owner string Current user id (default "tahsin")
--provider string Provider name
--zone string Cloud provider zone name
Global Flags:
--alsologtostderr log to standard error as well as files
--analytics Send analytical events to Google Guard (default true)
--config-file string Path to Pharmer config file
--env string Environment used to enable debugging (default "prod")
--kubeconfig string Paths to a kubeconfig. Only required if out-of-cluster.
--log_backtrace_at traceLocation when logging hits line file:N, emit a stack trace (default :0)
--log_dir string If non-empty, write log files in this directory
--logtostderr log to standard error instead of files (default true)
--master string The address of the Kubernetes API server. Overrides any value in kubeconfig. Only required if out-of-cluster.
--stderrthreshold severity logs at or above this threshold go to stderr
-v, --v Level log level for V logs
--vmodule moduleSpec comma-separated list of pattern=N settings for file-filtered logging
So, we need to run following command to create cluster with our information.
$ pharmer create cluster aws-1 \
--masters 3 \
--provider aws \
--zone us-east-1b \
--nodes t2.medium=1 \
--credential-uid aws \
--kubernetes-version v1.13.5

The directory structure of the storage provider will be look like:
$ tree ~/.pharmer/store.d/$USER/clusters/
/home/<user>/.pharmer/store.d/<user>/clusters/

6 directories, 15 files
Here,
- machine: conntains information about the master machines to be deployed
- machineset: contains information about the machinesets to be deployed
- pki: contains the cluster certificate information containing ca, front-proxy-ca, etcd/ca and service account keys sa
- ssh: has the ssh credentials on cluster’s nodes. With this key you can ssh into any node on a cluster
- aws-1.json: contains the cluster resource information
You can view your cluster configuration file by following command.
$ pharmer get cluster aws-1 -o yaml

You can modify this configuration by:
$ pharmer edit cluster aws-1
If everything looks ok, we can now apply the resources. This actually creates resources on aws.
Up to now we’ve only been working locally.
To apply run:
$ pharmer apply aws-1
Now, pharmer will apply that configuration, this create a Kubernetes cluster. After completing task the configuration file of the cluster will be look like
$ pharmer get cluster aws-1 -o yaml

Here,
status.phase: is ready. So, you can use your cluster from local machine.status.clusterApi.status.apiEndpoints is the cluster’s apiserver addressTo get the kubectl configuration file(kubeconfig) on your local filesystem run the following command.
$ pharmer use cluster aws-1
If you don’t have kubectl installed click here
Now you can run kubectl get nodes and verify that your kubernetes v1.13.5 is running.
NAME STATUS ROLES AGE VERSION ip-10-0-0-101.ec2.internal Ready master 5m37s v1.13.5 ip-10-0-0-239.ec2.internal Ready master 6m28s v1.13.5 ip-10-0-0-27.ec2.internal Ready node 5m37s v1.13.5 ip-10-0-0-71.ec2.internal Ready master 8m36s v1.13.5
You can ssh to the nodes from bastion node.
First, ssh to bastion node
$ cd ~/.pharmer/store.d/$USER/clusters/aws-1/ssh/
$ ssh-add id_aws-1-sshkey
Identity added: id_aws-1-sshkey (id_aws-1-sshkey)
$ ssh -A ubuntu@34.205.72.251 #bastion-ip
Then you can ssh to any node in the cluster from bastion node using its private ip
ubuntu@ip-10-0-1-245:~$ ssh 10.0.0.71
ubuntu@ip-10-0-0-71:~$
Scaling a cluster refers following meanings - Add new master and worker machines - Increment the number of nodes of a certain machine-set and machine-deployment - Decrement the number of nodes of a certain machine-set and machine-deployment - Introduce a new machine-set and machine-deployment with a number of nodes - Delete existing machine, machine-set and machine-deployments
You can see the machine and machine-sets deployed in the cluster
$ kubectl get machines

aws-1-master-2 27m

$ kubectl get machinesets

#### Create new machinesets
You can create new machinesets by deploying the following yaml
yaml apiVersion: cluster.k8s.io/v1alpha1 kind: MachineSet metadata: name: new-machineset namespace: default spec: replicas: 2 selector: matchLabels: cluster.k8s.io/cluster-name: aws-1 cluster.pharmer.io/mg: t2.medium template: metadata: labels: cluster.k8s.io/cluster-name: aws-1 cluster.pharmer.io/cluster: aws-1 cluster.pharmer.io/mg: t2.medium node-role.kubernetes.io/node: “” set: node spec: providerSpec: value: apiVersion: awsprovider/v1alpha1 iamInstanceProfile: node.aws-1.pharmer instanceType: t2.medium keyName: aws-1-sshkey kind: AWSMachineProviderSpec versions: kubelet: v1.13.5
#### Create new machine-deployments
You can create new machine-deployments by deploying the following yaml
yaml apiVersion: cluster.k8s.io/v1alpha1 kind: MachineDeployment metadata: name: new-machinedeployment namespace: default spec: replicas: 2 selector: matchLabels: cluster.k8s.io/cluster-name: aws-1 cluster.pharmer.io/mg: t2.medium template: metadata: labels: cluster.k8s.io/cluster-name: aws-1 cluster.pharmer.io/cluster: aws-1 cluster.pharmer.io/mg: t2.medium node-role.kubernetes.io/node: “” set: node spec: providerSpec: value: apiVersion: awsprovider/v1alpha1 iamInstanceProfile: node.aws-1.pharmer instanceType: t2.medium keyName: aws-1-sshkey kind: AWSMachineProviderSpec versions: kubelet: v1.13.5
#### Scale Cluster
You can also update number of nodes of an existing machine-set and machine-deployment using
console
$ kubectl edit
and update the `spec.replicas` field
#### Delete nodes
You can delete machines using
console
$ kubectl delete machine
Warning: if the machine is controlled by a machineset, a new machine will be created. You should update/delete machineset in that case
You can delete machine-set and machine-deployments using
console
$ kubectl delete machineset
### Cluster Upgrading
#### Upgrade master machines
You can deploy new master machines with specifying new version in `spec.version.controlPlane` and `spec.version.kubelet`. After new master machines are ready, you can safely delete old ones
#### Upgrade worker machines
You can upgrade worker machines by editing machine-deployment
console
$ kubectl edit machinedeployments
and updating the `spec.version.kubelet`
To upgrade machinesets, you have to deploy new machinesets with specifying new version in `spec.template.spec.version.kubelet`
After new machines are ready, you can safely delete old machine-sets
## Cluster Deleting
To delete your cluster run
console $ pharmer delete cluster aws-1
Then, the yaml file looks like
yaml $ pharmer get cluster a1 -o yaml kind: Cluster apiVersion: cluster.pharmer.io/v1beta1 metadata: name: aws-1 uid: 740dbfc4-77a5-11e9-9087-e0d55ee85d14 generation: 1557988811187811600 creationTimestamp: ‘2019-05-16T06:40:11Z’ deletionTimestamp: ‘2019-05-16T08:18:45Z’ … … … status: phase: Deleting … …
Here,
- `metadata.deletionTimestamp`: is set when cluster deletion command was applied.
Now, to apply delete operation of the cluster, run
console $ pharmer apply aws-1 ```
Congratulations !!! , you’re an official pharmer user now.
