Kubernetes上にmattermostを構築する

本記事の内容

mattermostをkubernetes上に構築する方法のまとめ。

1. githubからmanifestとかを取ってくる

bash

vagrant@vagrant:~$ git clone https://github.com/mattermost/mattermost-docker.git

2. PostgreSQLをdeployする

bash

vagrant@vagrant:~$ kubectl run postgres --image=postgres:9 \
  --env="POSTGRES_PASSWORD=mmuser_password" \
  --env="POSTGRES_DB=mattermost" \
  --env="POSTGRES_USER=mmuser"

vagrant@vagrant:~$ kubectl expose deployment postgres \
   --name=db \
   --port 5432 \
   --target-port 5432

3. secretをdeployする

bash

vagrant@vagrant:~/mattermost-docker/contrib/kubernetes$ kubectl apply -f mattermost.secret.yaml

4. mattermostのdeploymentをdeployする

bash

### manifestの書き方が古いので最新化する
vagrant@vagrant:~/mattermost-docker/contrib/kubernetes$ git diff
diff --git a/contrib/kubernetes/mattermost.deployment.yaml b/contrib/kubernetes/mattermost.deployment.yaml
index 8c14390..20ea85d 100644

### deplyする
vagrant@vagrant:~/mattermost-docker/contrib/kubernetes$ kubectl apply -f mattermost.deployment.yaml
deployment.apps/mattermost-app created

5.mattermostのserviceをdeployする

bash

vagrant@vagrant:~/mattermost-docker/contrib/kubernetes$ kubectl create -f mattermost.svc.yaml
service/mattermost created
vagrant@vagrant:~/mattermost-docker/contrib/kubernetes$ kubectl get svc mattermost
NAME         TYPE       CLUSTER-IP      EXTERNAL-IP   PORT(S)        AGE
mattermost   NodePort   10.99.213.175   <none>        80:32383/TCP   38m
vagrant@vagrant:~/mattermost-docker/contrib/kubernetes$
