海外TECH	DEV Community	Deploying PostgreSQL in a Local Kubernetes Cluster	https://dev.to/otomato_io/deploying-postgresql-in-a-local-kubernetes-cluster-230n	Deploying PostgreSQL in a Local Kubernetes ClusterIn this article the author will not explain why all these manipulations are needed or discuss the advantages and disadvantages of this solution He hopes readers are smart enough Think of this article as a continuation of the persistent volumes story and as a guide for deploying a database in a local Kubernetes dev cluster IntroductionThree main stages can be distinguished Creation of PersistentVolume PV and PersistentVolumeClaim PVC what a surpise we need a stateful app Setting the Helm chart of the target application Checking that everything is working Before starting work we need to minimally configure the Kubernetes cluster Here are the small requirements The actual version of Kubernetes v One master node and one worker node The configured Ingress controller helm is installed on the dev s machine As you may know already the author prefers to use ks kd as his local Kubernetes development stage Storage preparationWhen dealing with ks you have to enable so called local path provisoner first Create directory that s needed by local provisioner i e mkdir opt local path provisionerInstall the provisioner kubectl apply f Set the local path provisioner as default kubectl patch storageclass local path p metadata annotations storageclass kubernetes io is default class true Check the fact provisioner is running kubectl namespace kube system get pod NAME READY STATUS RESTARTS AGE local path provisioner bb tmpht Running From this moment we can create a PersistentVolume and PersistentVolumeClaim resources for our dedicated storage space To do this paste the following manifest into the pv yaml file apiVersion vkind PersistentVolumemetadata name pv for pg labels type localspec capacity storage Gi volumeMode Filesystem accessModes ReadWriteOnce persistentVolumeReclaimPolicy Retain storageClassName local path hostPath path opt local path provisioner nodeAffinity required nodeSelectorTerms matchExpressions key kubernetes io hostname operator In values kd my cluster agent kind PersistentVolumeClaimapiVersion vmetadata name pg pvcspec storageClassName local path accessModes ReadWriteOnce resources requests storage GiIn matchExpressions field we specify the name of the node on which the disk will be mounted should be our worker node kd my cluster agent here For convenience we will mount the disk immediately on the master node although this can be done on any of those available in the list We will mount volume on the opt local path provisioner directory created earlier See the result kubectl apply f pvc yaml persistentvolume pv for pg createdpersistentvolumeclaim pg pvc createdGood Let s check promoted PersistentVolumeClaim s state kubectl get pvcNAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGEpg pvc Bound pv for pg Gi RWO local path msAs we may see the PersistentVolumeClaim resource is bound Installing PostgreSQLNow is the time to deploy Postgres on a cluster Just at this stage we already need helm We pull the Bitnami repository to ourselves they are kind and great they have a lot of useful ready made charts there in their k repository helm repo add bitnami bitnami has been added to your repositoriesProceed with helm install helm install dev pg bitnami postgresql set primary persistence existingClaim pg pvc auth postgresPassword pgpass volumePermissions enabled trueNAME dev pgLAST DEPLOYED Tue May NAMESPACE defaultSTATUS deployedREVISION ️Due to an on going issue regarding kubernetes permissions and the use of containerSecurityContext runAsUser you must enable volumePermissions to ensure everything works as expected Drums are ticking From now the Postgres Pod will capable to write data to the opt local path provisioner directory Let s look at the state of the Pod and StatefulSet kubectl get pod statefulsetNAME READY STATUS RESTARTS AGEpod dev pg postgresql Running mNAME READY AGEstatefulset apps dev pg postgresql hCheck the version kubectl logs tail dev pg postgresql grep starting LOG starting PostgreSQL on x pc linux gnu compiled by gcc Debian bitGreat job Communicating with the databaseThe database has been successfully deployed now let s try to connect to it create a user a table and configure access credentials There are two major ways to communicate with DB Port forwarding Involving Pod with client tool onboard Port forwardingWe ll need the psql utility note in some cases PgSQL PPA repo should be added the author uses Ubuntu Focal sudo apt install postgresql client Let s export the password from the admin user to an environment variable export POSTGRES PASSWORD kubectl get secret namespace default dev pg postgresql o jsonpath data postgres password base decode Perform port forwarding Keep in mind the current console will be locked after executing the command kubectl port forward namespace default svc dev pg postgresql Or you may open a separate console export KUBECONFIG kd kubeconfig write my cluster kubectl port forward namespace default svc dev pg postgresql Now connect to database PGPASSWORD POSTGRES PASSWORD psql host U postgres d postgres p psql Ubuntu pgdg b Type help for help postgres Involving Pod with client tool onboardExport the password from the admin user to an environment variable export POSTGRES PASSWORD kubectl get secret namespace default dev pg postgresql o jsonpath data postgres password base decode Then let s create a Pod with the psql utility onboard and execute the command to connect to the database in it kubectl run dev pg postgresql client rm tty i restart Never namespace default image docker io bitnami postgresql debian r env PGPASSWORD POSTGRES PASSWORD gt command psql host dev pg postgresql U postgres d postgres p If you don t see a command prompt try pressing enter postgres Let s list roles to ensure we re in touch postgres du List of roles Role name Attributes Member of postgres Superuser Create role Create DB Replication Bypass RLS postgres That s it guys We have deployed a working database in a cluster it also saves its state it is stateful database here To be continued	2022-05-03 22:29:16
