Istio在Openshift 3.11的安装

Posted 2021-01-27 ericnie

详细安装步骤及解释参考

https://docs.openshift.com/container-platform/3.11/servicemesh-install/servicemesh-install.html#servicemesh-installation-overview

 

1.设置virtualbox能够上网

添加网络地址转换NAT网卡，并且编辑network-script

[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-enp0s8
TYPE="Ethernet"
#PROXY_METHOD="none"
BOOTPROTO="dhcp"
#IPADDR=192.168.56.103
#NETMASK=255.255.255.0
#GATEWAY=192.168.64.254
DNS1=202.106.0.20
DNS2=114.114.114.114
NAME="enp0s8"
DEVICE="enp0s8"
ONBOOT="yes"
DEFROUTE=yes

删除enp0s3的GATEWAY选项，验证是否能上网。

如果离线安装需要下载的镜像包括

openshift-istio-tech-preview/istio-operator:0.5.0
openshift-istio-tech-preview/openshift-ansible：0.5.0
openshift-istio-tech-preview/citadel:0.5.0
openshift-istio-tech-preview/proxyv2:0.5.0
openshift-istio-tech-preview/pilot:0.5.0
openshift-istio-tech-preview/mixer:0.5.0
docker.io/prom/prometheus:v2.3.1

openshift-istio-tech-preview/galley:0.5.0
openshift-istio-tech-preview/sidecar-injector:0.5.0

distributed-tracing-tech-preview/jaeger-elasticsearch:5.6.10
grafana/grafana:5.2.3
distributed-tracing-tech-preview/jaeger-agent:1.8.1
distributed-tracing-tech-preview/jaeger-collector:1.8.1
distributed-tracing-tech-preview/jaeger-query:1.8.1
kiali/kiali:v0.10.1

但最后还需要建立一个github,把代码clone过去

https://github.com/fabric8-launcher/launcher-booster-catalog.git

所以最后还是选择联互联网。

 

2. 准备工作

每台机器新建立一个/etc/sysctl.d/99-elasticsearch.conf文件，添加

vm.max_map_count = 262144

#sysctl vm.max_map_count=262144

在master机器上建立/etc/origin/master/master-config.patch文件

admissionConfig:
  pluginConfig:
    MutatingAdmissionWebhook:
      configuration:
        apiVersion: apiserver.config.k8s.io/v1alpha1
        kubeConfigFile: /dev/null
        kind: WebhookAdmission
    ValidatingAdmissionWebhook:
      configuration:
        apiVersion: apiserver.config.k8s.io/v1alpha1
        kubeConfigFile: /dev/null
        kind: WebhookAdmission

然后

$ cp -p master-config.yaml master-config.yaml.prepatch
$ oc ex config patch master-config.yaml.prepatch -p "$(cat master-config.patch)" > master-config.yaml
$ /usr/local/bin/master-restart api && /usr/local/bin/master-restart controllers

 

3.安装
