Kubernetes阿里阿里云logtail
本文档基于自建Kubernetes平台使用阿里云logtail日志插件，收集Kubernetes标准输出日志
以下是官方文档链接地址
官方安装logtail：
官方通过DaemonSet-控制台方式采集Kubernetes标准输出：
如何安装helm：
以下所有操作都在Kubernetes Master节点上执行
- 下载安装脚本，如下
wget http://logtail-release-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/kubernetes/alicloud-log-k8s-custom-install.sh;chmod 744 ./alicloud-log-k8s-custom-install.sh
- 编辑安装脚本，根据环境自定义
# cat alicloud-log-k8s-custom-install.sh
#!/bin/bash
if [ $# -le 4 ] ; then
echo "[Invalid Param], use sudo ./install-k8s-log.sh {your-project-suffix} {regionId} {aliuid} {accessKeyId} {accessKeySecret}"
exit 1
fi
# project环境变量，根据自己需求定义，最终在SLS生成的project名称为kubernetes-$1
project="kubernetes-"$1
regionId=$2
aliuid=$3
accessKeyId=$4
accessKeySecret=$5
helmPackageUrl="http://logtail-release-$regionId.oss-$regionId.aliyuncs.com/kubernetes/alibaba-cloud-log.tgz"
wget $helmPackageUrl -O alibaba-cloud-log.tgz
if [ $? != 0 ]; then
echo "[FAIL] download alibaba-cloud-log.tgz from $helmPackageUrl failed"
exit 1
fi
helmV3=`helm version | grep v3 | wc -l`
if [ $helmV3 -eq 0 ]; then
echo "install alibaba-log-controller using helm v2 command."
helm install alibaba-cloud-log.tgz --name alibaba-log-controller --set ProjectName=$project --set RegionId=$regionId --set InstallParam=$regionId"_internet" # 注意与上文的project是一样的
--set MachineGroupId="kubernetes-"$1 --set Endpoint=$regionId".log.aliyuncs.com" --set AlibabaCloudUserId=":"$aliuid --set AlibabaCloudK8SCluster="false" --set Privileged="true" --set AccessKeyId=$accessKeyId --set AccessKeySecret=$accessKeySecret --set LogtailImage.Repository="registry.$regionId.aliyuncs.com/log-service/logtail" --set ControllerImage.Repository="registry.$regionId.aliyuncs.com/log-service/alibabacloud-log-controller"
else
echo "install alibaba-log-controller using helm v3 command."
helm install alibaba-log-controller alibaba-cloud-log.tgz --set ProjectName=$project --set RegionId=$regionId --set InstallParam=$regionId"_internet" # 注意与上文的project是一样的
--set MachineGroupId="kubernetes-"$1 --set Endpoint=$regionId".log.aliyuncs.com" --set AlibabaCloudUserId=":"$aliuid --set AlibabaCloudK8SCluster="false" --set Privileged="true" --set AccessKeyId=$accessKeyId --set AccessKeySecret=$accessKeySecret --set LogtailImage.Repository="registry.$regionId.aliyuncs.com/log-service/logtail" --set ControllerImage.Repository="registry.$regionId.aliyuncs.com/log-service/alibabacloud-log-controller"
fi
installRst=$?
if [ $installRst -eq 0 ]; then
echo [INFO] your k8s is using project : $project, region : $regionId, aliuid : $aliuid, accessKeyId : $accessKeyId
echo "[SUCCESS] install helm package : alibaba-log-controller success."
exit 0
else
echo "[FAIL] install helm package failed, errno " $installRst
exit 0
fi
- 安装helm
- 安装alibaba-log-controller，如下
sh ./alicloud-log-k8s-custom-install.sh {your-project-suffix} {region-id} {aliuid} {access-key-id} {access-key-secret}
具体带入的参数解释请参考官方文档

具体最终执行命令如下：
sh ./alicloud-log-k8s-custom-install.sh non-production cn-hangzhou 1358359200279133 LTAI4FqfAcMq2fUts7kpP7VK SK(根据自己申请的SK填充)
# sh ./alicloud-log-k8s-custom-install.sh prod cn-hangzhou aliuid LTAI4FqfAcMq2fUts7kpP7VK SK
