Docker-Compose HAProxy缺less前端
我正在尝试使用HAProxy作为使用redis的python webapp的负载平衡器。 我正在使用docker-compose.yml将docker run命令转换为docker-compose – 但是我遇到了问题
下面是我目前的“docker运行”命令，它工作得很好！
docker run --name sdnapi-redis -v /opt/redis:/data -p 6379:6379 -d redis redis-server --appendonly yes docker run -d --name sdnapi1 --link sdnapi-redis:redis mycomp/sdnapi docker run -d --name sdnapi2 --link sdnapi-redis:redis mycomp/sdnapi docker run -d --name sdnapilb -p 80:80 -p 443:443 -p 1936:1936 -e DEFAULT_SSL_CERT="$(awk 1 ORS='\\n' ./certs/cert.pem)" -v /certs/:/certs/ --link sdnapi1:sdnapi1 --link sdnapi2:sdnapi2 dockercloud/haproxy 这是我的docker-compose.yml应该复制相同的function
version: '2' services: sdnapi: image: mycomp/sdnapi links: - sdnapi-redis:redis sdnapilb: image: dockercloud/haproxy:1.2.1 environment: - DEFAULT_SSL_CERT volumes: - /certs/:/certs/ ports: - "80:80" - "443:443" - "1936:1936" links: - sdnapi:sdnapi sdnapi-redis: image: redis volumes: - /opt/redis:/data ports: - "6379:6379" command: redis-server --appendonly yes
当我运行docker运行命令时，这是sdnapilb日志：

当我用“docker-compose up -d”运行docker-compose.yml时，我失去了前端部分。

你能看到任何设置的任何问题？ 我想用docker-compose来扩展它的能力。
我想出了这个问题
docker-compose.yml与链接有问题..链接的格式是服务名称 ： 别名
我的问题是，即使我的服务名称是正确的， 别名'是不正确的 ……导致docker组成失败，没有一个实际的错误。 由于别名不存在，它只是不链接容器 – 因此没有前端
