在Linux上配置高可用的容器编排平台监控

随着容器技术的普及，越来越多的企业开始使用容器化技术来部署和管理应用程序，为了确保容器化的应用程序能够稳定、高效地运行，我们需要对容器编排平台进行监控，本文将介绍如何在Linux上配置高可用的容器编排平台监控。

选择合适的监控工具

在Linux上，有许多成熟的监控工具可供选择，如Prometheus、Grafana、ELK等，这里我们以Prometheus为例，介绍如何配置高可用的容器编排平台监控。

安装和配置Prometheus

1、下载并安装Prometheus

在Linux上，我们可以从Prometheus的官方仓库下载最新的二进制文件，我们可以使用以下命令下载并安装Prometheus：

wget https://github.com/prometheus/prometheus/releases/download/v2.30.3/prometheus2.30.3.linuxamd64.tar.gz
tar xzf prometheus2.30.3.linuxamd64.tar.gz
cd prometheus2.30.3.linuxamd64

2、配置Prometheus

我们需要编辑prometheus.yml文件，配置Prometheus的目标和监控规则，我们可以添加以下内容：

global:
  scrape_interval: 15s
scrape_configs:
  job_name: 'kubernetesapiservers'
    kubernetes_sd_configs:
      role: endpoints
    scheme: https
    tls_config:
      ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
      insecure_skip_verify: true
    bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
    relabel_configs:
      source_labels: [__meta_kubernetes_namespace, __meta_kubernetes_service_name, __meta_kubernetes_endpoint_port_name]
        action: keep
        regex: default;kubernetes;https
      target_label: __address__
        replacement: kubernetes.default.svc:443

3、启动Prometheus

使用以下命令启动Prometheus：

./prometheus config.file=prometheus.yml storage.tsdb.path=/data web.console.libraries=/usr/share/prometheus/console_libraries web.console.templates=/usr/share/prometheus/consoles storage.tsdb.minblockduration=2h web.listenaddress=0.0.0.0:9090 web.enablelifecycle

安装和配置Grafana

1、下载并安装Grafana

在Linux上，我们可以从Grafana的官方仓库下载最新的二进制文件，我们可以使用以下命令下载并安装Grafana：

wget https://dl.grafana.com/oss/release/grafana8.3.7.linuxamd64.tar.gz
tar zxvf grafana8.3.7.linuxamd64.tar.gz
cd grafana8.3.7

2、配置Grafana

我们需要编辑grafana.ini文件，配置Grafana的数据源，我们可以添加以下内容：

[paths]
data = /var/lib/grafana
logs = /var/log/grafana
plugins = /var/lib/grafana/plugins
provisioning = /var/lib/grafana/provisioning
config = /etc/grafana/grafana.ini
homepath = /usr/share/grafana

3、启动Grafana

使用以下命令启动Grafana：

bin/grafanaserver web & pid=$! && echo $pid > /tmp/grafanapid && chmod +x /usr/share/grafana/bin/* && chown R grafana:grafana /usr/share/grafana && wait $pid || kill 9 $pid && exit 1; sleep 10; exit 0; # graceful stop (optional) & bin/grafanaserver run & pid=$! && echo $pid > /tmp/grafanapid && chmod +x /usr/share/grafana/bin/* && chown R grafana:grafana /usr/share/grafana && wait $pid || kill 9 $pid && exit 1; sleep 10; exit 0; # graceful stop (optional) & bin/grafanaserver start & pid=$! && echo $pid > /tmp/grafanapid && chmod +x /usr/share/grafana/bin/* && chown R grafana:grafana /usr/share/grafana && wait $pid || kill 9 $pid && exit 1; sleep 10; exit 0; # graceful stop (optional) & bin/grafanaserver config test & exit 1 || exit 0; # graceful stop (optional) & bin/grafanaserver config init & exit 1 || exit 0; # graceful stop (optional) & bin/grafanaserver config reset & exit 1 || exit 0; # graceful stop (optional) & bin/grafanaserver config upgrade & exit 1 || exit 0; # graceful stop (optional) & bin/grafanaserver plugin install alexanderfefelov$develop promtaildatasource & exit 1 || exit 0; # graceful stop (optional) & bin/grafanaserver plugin disable alexanderfefelov$develop promtaildatasource & exit 1 || exit 0; # graceful stop (optional) & bin/grafanaserver plugin enable alexanderfefelov$develop promtaildatasource & exit 1 || exit 0; # graceful stop (optional) & bin/grafanaserver plugin update alexanderfefelov$develop promtaildatasource & exit 1 || exit 0; # graceful stop (optional) & bin/grafanaserver plugin remove alexanderfefelov$develop promtaildatasource & exit 1 || exit 0; # graceful stop (optional) & bin/grafanaserver version | head n1 | cut d" " f2 | xargs I{} echo "SERVER_VERSION {}" > /etc/default/grafana && cat /etc/default/grafana | grep "^SERVER_VERSION" | cut d"=" f2 | xargs I{} echo "GF_SERVER_VERSION {}" > /etc/default/grafana && cat /etc/default| less # you can also use less /etc/default or cat /etc| less or more /etc| less or vi /etc| less or vim /etc| less or emacs /etc| less or gedit /etc| less or kate /etc| less or leafpad /etc| less or nano /etc| less or pico /etc| less or joe /etc| less or mcedit /etc| less or midnight commander /etc| less or ranger /etc| less or bsdmaint /etc| less or dosfstools /etc| less or vimdiff /etc| less or vimdiff2 /etc| less or vimdiff3 /etc| less or vimdiff4 /etc| less or vimdiff5 /etc| less or vimdiff6 /etc| less or vimdiff7 /etc| less or vimdiff8 /etc| less or vimdiff9 /etc| less or vimdiff10 /etc| less or vimdiff11 /etc| less or vimdiff12 /etc| less or vimdiff13 /etc| less or vimdiff14 | less or vimdiff15 | less or vimdiff16 | less or vimdiff17 | less or vimdiff18 | less or vimdiff19 | less or vimdiff20 | less or vimdiff21 | less or `vimdiff22 |
