2.2 集成策略规划
制定明确的集成策略,包括Podman与云原生平台的集成方式、镜像管理、网络配置、存储配置等。
Part03-生产环境项目实施方案
3.1 Kubernetes集成
将Podman与Kubernetes集成,实现容器的编排和管理。
3.2 OpenShift集成
将Podman与OpenShift集成,实现容器的编排和管理。
3.3 云原生工具集成
集成云原生工具,如Prometheus、Grafana、ELK Stack等,实现容器的监控和管理。
Part04-生产案例与实战讲解
4.1 Kubernetes集成实战
Podman与Kubernetes集成:
podman generate kube fgedu-pod > fgedu-pod.yaml
# 查看生成的YAML文件
cat fgedu-pod.yaml
# Save the output of this file and use kubectl create -f to import
# it into Kubernetes.
#
# Created with podman-4.9.0
apiVersion: v1
kind: Pod
metadata:
creationTimestamp: “2026-04-10T00:00:00Z”
labels:
app: fgedu-app
name: fgedu-pod
spec:
containers:
– command:
– nginx
– -g
– daemon off;
image: docker.io/library/nginx:latest
name: fgedu-nginx
ports:
– containerPort: 80
hostPort: 8080
protocol: TCP
resources: {}
restartPolicy: Never
# 在Kubernetes中部署
kubectl apply -f fgedu-pod.yaml
pod/fgedu-pod created
# 查看Pod状态
kubectl get pods
NAME READY STATUS RESTARTS AGE
fgedu-pod 1/1 Running 0 5m
4.2 OpenShift集成实战
Podman与OpenShift集成:
oc login https://api.openshift.example.com:6443 –username=admin –password=password
# 创建项目
oc new-project fgedu-project
Now using project “fgedu-project” on server “https://api.openshift.example.com:6443”.
# 构建镜像
oc new-build –name=fgedu-app –binary –strategy=docker
–> Found image 8f7890abcdef (2 weeks old) in image stream “openshift/docker” under tag “latest” for “docker”
* A Docker build using binary input will be created
* The resulting image will be pushed to image stream tag “fgedu-app:latest”
* A binary build was created, use ‘oc start-build fgedu-app –from-dir=.’ to trigger a new build
–> Creating resources with label build=fgedu-app …
buildconfig.build.openshift.io/fgedu-app created
imagestream.image.openshift.io/fgedu-app created
–> Success
# 启动构建
oc start-build fgedu-app –from-dir=.
build.build.openshift.io/fgedu-app-1 created
# 部署应用
oc new-app fgedu-app
–> Found image abcdef123456 (5 minutes old) in image stream “fgedu-project/fgedu-app” under tag “latest” for “fgedu-app”
* This image will be deployed in deployment config “fgedu-app”
* Ports 80/tcp, 443/tcp will be load balanced by service “fgedu-app”
* Other containers can access this service through the hostname “fgedu-app”
–> Creating resources …
deploymentconfig.apps.openshift.io/fgedu-app created
service/fgedu-app created
–> Success
Application is not exposed. You can expose services to the outside world by executing one or more of the commands below:
‘oc expose service/fgedu-app’
Run ‘oc status’ to view your app.
# 暴露服务
oc expose service/fgedu-app
route.route.openshift.io/fgedu-app exposed
4.3 云原生工具集成实战
云原生工具集成:
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm install prometheus prometheus-community/kube-prometheus-stack
# 查看部署状态
kubectl get pods | grep -E “prometheus|grafana”
NAME READY STATUS RESTARTS AGE
prometheus-kube-prometheus-operator-67890 1/1 Running 0 5m
prometheus-kube-prometheus-prometheus-12345 2/2 Running 0 5m
prometheus-grafana-67890 1/1 Running 0 5m
# 部署ELK Stack
helm repo add elastic https://helm.elastic.co
helm install elasticsearch elastic/elasticsearch
helm install kibana elastic/kibana
helm install filebeat elastic/filebeat
# 查看部署状态
kubectl get pods | grep -E “elasticsearch|kibana|filebeat”
NAME READY STATUS RESTARTS AGE
elasticsearch-master-0 1/1 Running 0 5m
kibana-67890 1/1 Running 0 5m
filebeat-abcde 1/1 Running 0 5m
filebeat-fghij 1/1 Running 0 5m
