我正在尝试更改本地minikube集群中的postgres数据库的设置。我错误地部署了数据库,但未指定postgres用户,密码和数据库。
问题:当我添加新的环境变量并使用kubectl apply -f postgres-deployment.yml
时,postgres不会创建由环境变量指定的用户,密码或数据库。
这是部署:
apiVersion: apps/v1
kind: Deployment
metadata:
name: postgres-deployment
spec:
replicas: 1
selector:
matchLabels:
component: postgres
template:
metadata:
labels:
component: postgres
spec:
volumes:
- name: postgres-storage
persistentVolumeClaim:
claimName: database-persistent-volume-claim
containers:
- name: postgres
image: postgres
ports:
- containerPort: 5432
volumeMounts:
- name: postgres-storage
mountPath: /var/lib/postgresql/data
subPath: postgres
env:
- name: PGUSER
value: admin
- name: PGPASSWORD
value: password
- name: PGDATABSE
value: testdb
应用部署文件时如何更改postgres的设置?
答案 0 :(得分:0)
您可以共享Pod的日志吗?
kubectl logs <pod_name>
Postgres正在使用具有已定义变量名称的初始化脚本:
POSTGRES_USER
POSTGRES_PASSWORD
POSTGRES_DB
试试这个
apiVersion: v1
kind: ReplicationController
metadata:
name: postgres
spec:
replicas: 1
template:
metadata:
labels:
app: postgres
spec:
containers:
- name: postgres
image: postgres:9.6
env:
- name: POSTGRES_USER
value: admin
- name: POSTGRES_PASSWORD
value: password
- name: POSTGRES_DB
value: testdb
- name: PGDATA
value: /var/lib/postgresql/data/pgdata
ports:
- containerPort: 5432
volumeMounts:
- mountPath: /var/lib/postgresql/data
name: pg-data
volumes:
- name: pg-data
emptyDir: {}
