openshift4.3.22离线安装

准备bastion节点,离线包下载

1 bastion节点安装操作系统redhat7.8LE版本

2 设置主机名

hostnamectl set-hostname bastion.ocp4.example.com

3 安装相关工具软件

yum -y install podman httpd httpd-tools vim 

4 安装配置DNS和DHCP (option)

yum -y  install dnsmasq

配置通过ocp4/helpernode完成

5 安装配置HAProxy(option)

yum -y  install haproxy

配置通过ocp4/helpernode完成

6  创建内部镜像仓库

此仓库用于存放用于部署openshift平台所需使用的镜像,仓库本身也是用容器启动的。安装所需软件包,及创建所需目录,这些文件夹将挂载到registry容器中。

DNS本地解析

cat <> /etc/hosts

172.16.167.175  bastion.ocp4.example.com

172.16.167.175  registry.ocp4.example.com

EOF


创建给本地镜像库使用的相关目录

mkdir-p/opt/registry/{auth,certs,data}

创建证书输入你相关信息

注意:Common Name (eg, your name or your server's hostname) 字段要填写镜像仓库的域名,不能使用IP。其他的可以空着,这一步我错了几次,如下:


cd /opt/registry/certs

openssl req -newkey rsa:4096 -nodes -sha256 -keyout domain.key -x509 -days 365 -out domain.crt

创建密码文件

htpasswd -bBc /opt/registry/auth/htpasswd admin admin

更新Linux系统证书

cp /opt/registry/certs/domain.crt /etc/pki/ca-trust/source/anchors/

update-ca-trust

使用一个镜像来部署私有镜像仓库:

podman run --name mirror-registry -p 5000:5000 \

      -v /opt/registry/data:/var/lib/registry:z \

      -v /opt/registry/auth:/auth:z \

      -e "REGISTRY_AUTH=htpasswd" \

      -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \

      -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd \

      -v /opt/registry/certs:/certs:z \

      -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \

      -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key \

      -d docker.io/ppc64le/registry:2

加入防火墙规则

firewall-cmd --add-port=5000/tcp --zone=internal --permanent

firewall-cmd --add-port=5000/tcp --zone=public  --permanent

firewall-cmd --reload


测试镜像仓库是否能正常访问:

curl -u admin:admin -k https://registry.ocp4.example.com:5000/v2/_catalog

{"repositories":[]}

将镜像仓库的用户名密码镜像base64加密

echo -n 'admin:admin' | base64 -w0

YWRtaW46YWRtaW4=

下载openshift的镜像文件所需的pull_sercet文件

登录cloud.redhat.com使用账号和密码登录


openshift4.3.22离线安装_第2张图片

1 下载pull secret for OpenShift registry


openshift4.3.22离线安装_第3张图片

2  下载最新的oc命令。进入下载链接,

https://mirror.openshift.com/pub/openshift-v4/ppc64le/clients/ocp/stable-4.3/

下载

openshift-install-linux-4.3.22.tar.gz

openshift-client-linux-4.3.22.tar.gz



3 安装工具

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

yum -y install jq


4 解压openshift client和openshift install工具

tar -xzf openshift-client-linux-4.3.22.tar.gz -C /usr/local/bin/

tar -xzf openshift-install-linux-4.3.22.tar.gz -C /usr/local/bin/

将下载的pull_secret.txt格式化json文件pull_secret

mkdir -p ~/.openshift

cat ./pull-secret.txt | jq .  >  pull-secret

然后添加一下私有镜像仓库的内容,用于将quay的镜像同步到私有镜像仓库过程中需要做认证,这就是个认证密码文件,类似如下。

{ "auths": {

    "registry.ocp4.example.com:5000": {

      "auth": "YWRtaW46YWRtaW4=",

      "email": "[email protected]"

  }

}

}

完整的pull_secret如下

6 复制镜像

export BUILDNUMBER=4.3.22-ppc64le

echo ${BUILDNUMBER}

export OCP_RELEASE=${BUILDNUMBER}

export LOCAL_REG='registry.ose.example.com:5000'

export LOCAL_REPO='ocp4/openshift4'

export UPSTREAM_REPO='openshift-release-dev'

export LOCAL_SECRET_JSON="/home/ocp4.3/pull-secret.json"

export OPENSHIFT_INSTALL_RELEASE_IMAGE_OVERRIDE=${LOCAL_REG}/${LOCAL_REPO}:${OCP_RELEASE}

export RELEASE_NAME="ocp-release"


oc adm release mirror -a ${LOCAL_SECRET_JSON} \

--from=quay.io/${UPSTREAM_REPO}/${RELEASE_NAME}:${OCP_RELEASE} \

--to-release-image=${LOCAL_REG}/${LOCAL_REPO}:${OCP_RELEASE} \

--to=${LOCAL_REG}/${LOCAL_REPO}

镜像下载成功后显示如下信息

Success

Update image:  registry.ocp4.example.com:5000/ocp4/openshift4:4.3.22-ppc64le

Mirror prefix: registry.ocp4.example.com:5000/ocp4/openshift4

To use the new mirrored repository to install, add the following section to the install-config.yaml:

imageContentSources:

- mirrors:

  - registry.ocp4.example.com:5000/ocp4/openshift4

  source: quay.io/openshift-release-dev/ocp-release

- mirrors:

  - registry.ocp4.example.com:5000/ocp4/openshift4

  source: quay.io/openshift-release-dev/ocp-v4.0-art-dev

To use the new mirrored repository for upgrades, use the following to create an ImageContentSourcePolicy:

apiVersion: operator.openshift.io/v1alpha1

kind: ImageContentSourcePolicy

metadata:

  name: example

spec:

  repositoryDigestMirrors:

  - mirrors:

    - registry.ocp4.example.com:5000/ocp4/openshift4

    source: quay.io/openshift-release-dev/ocp-release

  - mirrors:

    - registry.ocp4.example.com:5000/ocp4/openshift4

    source: quay.io/openshift-release-dev/ocp-v4.0-art-dev

运行命令查看所有的镜像

在bastion节点上用redhat 部署工具ocp4_helpnoder安装配置相关服务DNS和DHCP ,HAProxy

1  安装ansible和git

git clone https://github.com/RedHatOfficial/ocp4-helpernode

cd ocp4-helpernode

3 cp docs/examples/vars-ppc64le.yaml .

重启systemctl restart named


5 开始安装

5.1 创建Ignition文件

mkdir ~/ocp4

cd ~/ocp4

mkdir -p ~/.openshift


查看helper_rsa文件是否存在

现在的ansible会帮助我们创建密钥文件

[root@bastion ocp4]# ls -l ~/.ssh/helper_rsa

-rw-------. 1 root root 3243 Jun  5 02:28 /root/.ssh/helper_rsa

准备创建install-config文件

首先获取每台虚拟机的mac地址


如果是libvirt 使用virt命令创建的虚拟机获取虚拟机mac地址的脚本


for i in bootstrap master{0..2} worker{0..1}

do

  echo -ne "${i}\t" ; virsh dumpxml ocp4-${i} | grep "mac address" | cut -d\' -f2

done

详细参考https://github.com/RedHatOfficial/ocp4-helpernode/blob/master/docs/quickstart-ppc64le.md

[root@bastion ocp4]# cd ~/ocp4

执行命令创建install-config文件

cat < install-config.yaml

apiVersion: v1

需要更新install-config.yaml中的additionalTrustBundle,和/opt/registry/certs/domain.crt一致

Web Console 登录

ocp4的web console 入口走router了,所以找下域名

首先找到我们的域名,然后在我们自己电脑上 hosts添加解析,指向到worker-0,这样就能够访问openshift 的web 控制台了

oc get route --all-namespaces |grep console-openshift


把172.16.167.175 oauth-openshift.apps.ocp4.example.com console-openshift-console.apps.ocp4.example.com 写入hosts文件


然后浏览器访问console

https://console-openshift-console.apps.ocp4.example.com


用户名是 kubeadmin

密码在这个文件里

cat /root/ocp4/auth/kubeadmin-password


或者通过下面命令拿到集群登录信息

trouble shooting

1 安装过程中master节点和work 节点使用的虚拟机配置文件是GMT+8 时区


RHCOS在PXE安装后是UTC时区

所以在安装基础架构节点的时候操作系统要设置时区为UTC

timedatectl  set-timezone UTC

注:各节点时间一定要一致


2  证书过期或者需要重新安装的时候


执行下面的命令 ,重新生成文件

rm  -rf ~/ocp4


openshift-install create ignition-configs

生成文件后重新复制到相关路径覆盖原文件


cp ~/ocp4/*.ign /var/www/html/ignition/

restorecon -vR /var/www/html/

chmod o+r /var/www/html/ignition/*.ign 

再次以PXE方式启动虚拟机开始重新安装

3 debug bootstrap

在bastion2节点上登录bootstrap节点

ssh core@bootstrap

# 检查方法:

# 查看网络信息

hostname -I

ip route show

cat /etc/resolv.conf

# 查看运行容器,sudo podman ps, 应该有运行中容器

# 如果没有在运行的容器, ps -ef 看下是否有podman pull 的进程

# 通过curl命令检查跟镜像仓库的连通性,我遇到过连不上仓库,在部署机上重启了下仓库后好了

sudo podman ps

sudo ps -ef

# 查看进程端口

netstat -an 查看 6443、22623

# 也可以通过haproxy的页面,就是192.168.2.10:9000 可以看到bootstrap的状态变成了绿色

# 说明这个时候bootstrap 已经部署成功

# 查看服务状态的命令,ssh进去的时候就会提示这条命令

journalctl -b -f -u bootkube.service
