Loki

依赖条件

  • 运行正常的 kubernetes ( v1.21+ )环境。安装手册参考 高可用集群 或 单节点集群
  • StorageClass
  • Minio（创建三个bucket，分别为chunks，ruler，admin）

开启 Loki 组件

  1. 编辑 /etc/kubez/globals.yml

  2. 取消 enable_loki: "no" 的注释，并设置为 "yes"，S3的相关参数需要根据自己的环境进行修改。

    ##############
# Loki Options
##############
enable_loki: "yes"

# Storage class to be used
loki_storage_class: managed-nfs-storage
# Size of persistent disk
loki_storage_size: 10Gi
# Should authentication be enabled
loki_auth_enabled: 'false'

# Number of replicas
loki_commonConfig_replication_factor_number: 2
# Number of customized loki read-write replicas
loki_read_replicas_number: 2
loki_write_replicas_number: 2

# Storage config
loki_storage_bucketNames_chunks: chunks
loki_storage_bucketNames_ruler: ruler
loki_storage_bucketNames_admin: admin

# S3 配置
s3:
  endpoint: http://172.17.16.13:9000
  secretAccessKey: minioadmin
  accessKeyId: minioadmin
  s3ForcePathStyle: true
  insecure: true

  3. 执行安装命令（根据实际情况选择）

    # 单节点集群场景
kubez-ansible apply

# 高可用集群场景
kubez-ansible -i multinode apply

  4. 部署完验证

    # 所有的 loki pod 均运行正常
[root@VM-16-13-centos ~]# kubectl get pods -n pixiu-system|grep loki
