Alertmanager Docker 启动报错

一、问题描述

• 使用自定义容器网络会发生这种情况，不使用自定义网络大概率不会导致有异常

root@manager-01:/data/compose/a$ docker compose up
WARN[0000] network default: network.external.name is deprecated. Please set network.name with external: true

1.1 官方 Dockerfile

• 官方仓库地址： https://github.com/prometheus/alertmanager/blob/main/Dockerfile
• 可以看出来 CMD 启动参数，覆盖启动参数即可

ARG ARCH="amd64"
ARG OS="linux"
FROM quay.io/prometheus/busybox-${OS}-${ARCH}:latest
LABEL maintainer="The Prometheus Authors <prometheus-developers@googlegroups.com>"

ARG ARCH="amd64"
ARG OS="linux"
COPY .build/${OS}-${ARCH}/amtool       /bin/amtool
COPY .build/${OS}-${ARCH}/alertmanager /bin/alertmanager
COPY examples/ha/alertmanager.yml      /etc/alertmanager/alertmanager.yml

RUN mkdir -p /alertmanager && \
    chown -R nobody:nobody etc/alertmanager /alertmanager

USER       nobody
EXPOSE     9093
VOLUME     [ "/alertmanager" ]
WORKDIR    /alertmanager
ENTRYPOINT [ "/bin/alertmanager" ]
CMD        [ "--config.file=/etc/alertmanager/alertmanager.yml", \
             "--storage.path=/alertmanager" ]

1.2、解决方法

• 覆盖启动参数，增加 --cluster.advertise-address=0.0.0.0:9093

version: '3'
services:
  alertmanager:
    image: prom/alertmanager:v0.24.0
    container_name: alertmanager
    restart: always
    command: "--config.file=/etc/alertmanager/alertmanager.yml --storage.path=/alertmanager --cluster.advertise-address=0.0.0.0:9093"
    environment:
      TZ: Asia/Shanghai
    volumes:
      - /etc/localtime:/etc/localtime
      # - /data/prometheus/conf/alertmanager.yml:/etc/alertmanager/alertmanager.yml
    ports:
      - "9093:9093"
networks:
  default:
    external:
      name:  aka-network
