使用docker编译打包sailfishos
开坑
- ubuntu HA_BUILD
用官方的ubuntu镜像即可，16.04或18.04都可以，不要用最新的20.04。一般来说启动之后的镜像除了手动指定的目录是持久化的，其他的会重启后失效，所以最好自己做一个镜像，把安卓编译环境安装上。
启动时映射本地目录，当作ANDROID_ROOT目录。
mer MER_BUILD

注意：必须是用域名的方式(也就是有内网的dns)，如果以前用ip，则本方法无效！
Harbor1.2之前的版本不能直接升级到新版本，想要升级到最新版并且业务不中断，可以采用如下方式。
大体流程如下：
B机器搭一个新harbor -> 手动将旧harbor的镜像push到新harbor -> 更改A域名指向到B主机ip ->
测试B的harbor服务是否正常 -> 铲掉A上的旧harbor -> 在A上重新搭建harbor -> B机器上的harbor同步到A上的harbor
测试A的harbor服务是否正常 -> 改回A域名指向A主机 -> 删掉B上的同步。
手动push旧harbor镜像到新harbor所用到的脚本：
pip install python_harborclient
get_all.py:
1 | #!/usr/bin/python |
python get_all.py > all_repos.txt
allimages=$(cat all_repos.txt)
ORIGIN_HOST=”pk8snode01.rmz.flamingo-inc.com:8888” #旧harbor
BACK_HOST=”pk8stemp02.rmz.flamingo-inc.com:8888” #新harbor
#提前登录一下
#docker login $BACK_HOST
for image in ${allimages}; do
docker pull ${ORIGIN_HOST}/$image
docker tag ${ORIGIN_HOST}/$image ${BACK_HOST}/$image
docker push ${BACK_HOST}/$image
sleep 1
echo $image “done”
done`

长时间运行的k8s节点可能会存在某些pod不自动退出，一直处于Terminating的状态
于是我们可以用这个脚本定时进行清理
1 | #!/bin/bash |
支持的变量
docker version --format '{{.Client.APIVersion}}'.对于即使已经不运行了也不想清理的镜像，使用KEEP_IMAGES变量处理，此处我们添写：
vmware/harbor-*:*,*calico:*,*registry:*,*kubernetes-dashboard-amd64:*,*nginx-ingress-controller:*,*cvallance/mongo-k8s-sidecar:*

使用DaemonSet+NodeSelector+Tolerations的方式定义Nginx Ingress Controller，给专门节点打上Label+Taint，使得这些专门节点只运行Nginx Ingress Controller，而不会调度和运行其他业务容器，只用来做代理节点。
在Kuberntes Cluster中准备N个节点，我们称之为代理节点。在这N个节点上只部署Nginx Ingress Controller（简称NIC）实例，不会跑其他业务容器。
给代理节点打上NoExecute Taint，防止业务容器调度或运行在这些节点。
kubectl taint nodes 10.8.8.234 LB=NIC:NoExecute
给代理节点打上Label，让NIC只部署在打了对应Lable的节点上。
kubectl label nodes 10.8.8.234 LB=NIC
修改calico-node配置，让calico可以在NoExecute节点上运行
