##### mysql
---
```bash
cd mysql
kubectl apply -f namespace.yaml
kubectl apply -f deployment.yaml
kubectl apply -f service.yaml
```
##### jira
---
[atlassian-agent.jar](https://gitee.com/hemleen/atlassian-agent.git) 下载地址

```shell
cd jira
docker build -t 172.25.42.235:5000/devops/jira:v1.0 .
kubectl apply -f namespace.yaml
kubectl apply -f deployment.yaml
kubectl apply -f service.yaml
# 把 jar.sql 刷到数据库里
```
##### confluence
---
[atlassian-agent.jar](https://gitee.com/hemleen/atlassian-agent.git) 下载地址

```shell
cd confluence
docker build -t 172.25.42.235:5000/devops/confluence:v1.0 .
kubectl apply -f namespace.yaml
kubectl apply -f deployment.yaml
kubectl apply -f service.yaml
# 把 confluence.sql 刷到数据库里
```

启动后，把数据库链接改成下面这个，然后重启服务器
vi /data/atlassian/application-data/confluence/confluence.cfg.xml
```xml
<property name="hibernate.connection.url">jdbc:mysql://127.0.0.1:3306/confluence?useUnicode=true&amp;characterEncoding=UTF-8&amp;useSSL=false&amp;sessionVariables=tx_isolation='READ-COMMITTED'</property>
```

##### ingress部署
---
1. 部署ingress-nginx

```
#下载ingress-nginx的yaml文件
#安装文档
https://kubernetes.github.io/ingress-nginx/deploy/

wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.30.0/deploy/static/mandatory.yaml

#删除目录
kubectl create -f mandatory.yaml


```
```yaml
#注意：mandatory.yaml中Deployment 设置hostNetwork为true
#也可使用 Deamonset 部署，需要把replicas去掉
#还可以配合 nodeSelector isIngress: "true" 部署在固定节点，做高可用架构
...
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-ingress-controller
  namespace: ingress-nginx
  labels:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app.kubernetes.io/name: ingress-nginx
      app.kubernetes.io/part-of: ingress-nginx
  template:
    metadata:
      labels:
        app.kubernetes.io/name: ingress-nginx
        app.kubernetes.io/part-of: ingress-nginx
      annotations:
        prometheus.io/port: "10254"
        prometheus.io/scrape: "true"
    spec:
      # hostNetwork设置为true
      hostNetwork: true
      # wait up to five minutes for the drain of connections
      terminationGracePeriodSeconds: 300
      nodeSelector:
        isIngress: "true"

...
```
#### 使用 Helm部署 Ingress-nginx

```bash
# 添加 ingress-nginx repo
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
# 查询 repo
helm search repo ingress-nginx
NAME                            CHART VERSION   APP VERSION     DESCRIPTION                                       
ingress-nginx/ingress-nginx     4.0.17          1.1.1           Ingress controller for Kubernetes using NGINX a...
# 更新repo
helm repo update
# 下载repo 到本地  方便修改
helm pull ingress-nginx/ingress-nginx --untar
# 新版本的ingress-nginx加了admission-webhook用于检验在ingress里面写的东西是否符合nginx的配置，防止出现ingress规则错误，导致ingress-nginx-controller无法启动的问题
```
ingress-nginx/values.yaml

```bash
# 来修改一下helm的配置
# 1.image需要修改一下，digest: 用不到的话就为空
# 2.一般内网情况下 controller.service.type=NodePort
# 3.把webhook禁用，controller.admissionWebhooks.enabled=false

# 4.hostNetwork: true,pod会绑定主机端口，这样把Service删除掉就可以了

# 5.当然也可以使用 kind: DaemonSet  + nodeSelector 模式，只需去改下配置
```
部署

```bash
helm upgrade --install ingress-nginx  -f values_test.yaml --namespace ingress-nginx --create-namespace .
Release "ingress-nginx" does not exist. Installing it now.
NAME: ingress-nginx
LAST DEPLOYED: Thu Feb 10 16:06:19 2022
NAMESPACE: ingress-nginx
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
The ingress-nginx controller has been installed.
Get the application URL by running these commands:
  export HTTP_NODE_PORT=$(kubectl --namespace ingress-nginx get services -o jsonpath="{.spec.ports[0].nodePort}" ingress-nginx-controller)
  export HTTPS_NODE_PORT=$(kubectl --namespace ingress-nginx get services -o jsonpath="{.spec.ports[1].nodePort}" ingress-nginx-controller)
  export NODE_IP=$(kubectl --namespace ingress-nginx get nodes -o jsonpath="{.items[0].status.addresses[1].address}")

  echo "Visit http://$NODE_IP:$HTTP_NODE_PORT to access your application via HTTP."
  echo "Visit https://$NODE_IP:$HTTPS_NODE_PORT to access your application via HTTPS."

An example Ingress that makes use of the controller:
  apiVersion: networking.k8s.io/v1
  kind: Ingress
  metadata:
    name: example
    namespace: foo
  spec:
    ingressClassName: nginx
    rules:
      - host: www.example.com
        http:
          paths:
            - backend:
                service:
                  name: exampleService
                  port:
                    number: 80
              path: /
    # This section is only required if TLS is to be enabled for the Ingress
    tls:
      - hosts:
        - www.example.com
        secretName: example-tls

If TLS is enabled for the Ingress, a Secret containing the certificate and key must also be provided:

  apiVersion: v1
  kind: Secret
  metadata:
    name: example-tls
    namespace: foo
  data:
    tls.crt: <base64 encoded cert>
    tls.key: <base64 encoded key>
  type: kubernetes.io/tls
```
