我根据此guide使用docker swarm设置了Traefik。它仅适用于SSL的单个节点。但是我将证书添加到群集上的其他节点。
更新所有节点的证书
docker node update --label-add traefik-public.traefik-public-certificates=true $NODE_ID
以管理员身份启动Traefik
docker service create \
--name traefik \
--constraint=node.labels.traefik-public.traefik-public-certificates==true \
--constraint=node.role==manager \
--publish 80:80 \
--publish 443:443 \
--mount type=bind,source=/var/run/docker.sock,target=/var/run/docker.sock \
--mount type=volume,source=traefik-public-certificates,target=/certificates \
--network traefik-public \
--label "traefik.frontend.rule=Host:monitor.$DOMAINNAME" \
--label "traefik.enable=true" \
--label "traefik.port=8080" \
--label "traefik.tags=traefik-public" \
--label "traefik.docker.network=traefik-public" \
--label "traefik.redirectorservice.frontend.entryPoints=http" \
--label "traefik.redirectorservice.frontend.redirect.entryPoint=https" \
--label "traefik.webservice.frontend.entryPoints=https" \
--label "traefik.frontend.auth.basic.users=${HTTP_USERNAME}:${HASHED_PASSWORD}" \
traefik:v1.7 \
--docker \
--docker.swarmmode \
--docker.watch \
--docker.exposedbydefault=false \
--constraints=tag==traefik-public \
--entrypoints='Name:http Address::80' \
--entrypoints='Name:https Address::443 TLS' \
