zhaobu opened a new issue #267:
URL: https://github.com/apache/apisix-docker/issues/267
### Issue description
使用官方的docker-compos文件,下面这一部分
```yaml
......
apisix:
image: apache/apisix:2.11.0-alpine
restart: always
volumes:
- ./apisix_log:/usr/local/apisix/logs
- ./apisix_conf/config.yaml:/usr/local/apisix/conf/config.yaml:ro
depends_on:
- etcd
##network_mode: host
ports:
- "9080:9080/tcp"
- "9091:9091/tcp"
- "9443:9443/tcp"
- "9092:9092/tcp"
networks:
apisix:
etcd:
image: bitnami/etcd:3.4.15
restart: always
volumes:
- etcd_data:/bitnami/etcd
environment:
ETCD_ENABLE_V2: "true"
ALLOW_NONE_AUTHENTICATION: "yes"
ETCD_ADVERTISE_CLIENT_URLS: "http://0.0.0.0:2379";
ETCD_LISTEN_CLIENT_URLS: "http://0.0.0.0:2379";
ports:
- "2379:2379/tcp"
networks:
apisix:
......
```
此时对应的apisix镜像的配置文件etcd部分是这样的
```yaml
......
etcd:
host: # it's possible to define multiple etcd
hosts addresses of the same etcd cluster.
- "http://etcd:2379"; # multiple etcd address
prefix: "/apisix" # apisix configurations prefix
timeout: 30 # 30 seconds
......
```
这是官方的默认配置是没有问题的.
如果把其中的etcd的部分改成下面这样
```yaml
mf_etcd:
image: bitnami/etcd:3.4.15
container_name: mf_etcd
restart: always
volumes:
- etcd_data:/bitnami/etcd
environment:
ETCD_ENABLE_V2: "true"
ALLOW_NONE_AUTHENTICATION: "yes"
ETCD_ADVERTISE_CLIENT_URLS: "http://0.0.0.0:2379";
ETCD_LISTEN_CLIENT_URLS: "http://0.0.0.0:2379";
ports:
- "2379:2379/tcp"
networks:
apisix:
```
此时对应的etcd配置应当修改为如下
```yaml
......
etcd:
host: # it's possible to define multiple etcd
hosts addresses of the same etcd cluster.
- "http://mf_etcd:2379"; # multiple etcd address
prefix: "/apisix" # apisix configurations prefix
timeout: 30 # 30 seconds
......
```
此时就会启动报错

```
### Steps to reproduce
1. 修改etcd 的label为mf_etcd,container_name为mf_etcd
2. 修改apisix的有关etcd部分的配置文件如下
```yaml
etcd:
host: # it's possible to define multiple etcd
hosts addresses of the same etcd cluster.
- "http://mf_etcd:2379"; # multiple etcd address
prefix: "/apisix" # apisix configurations prefix
timeout: 30 # 30 seconds
```
### Actual result
不能通过etcd的label名初始化

### Expected result
用docker-compose的label名或者容器的container都能正确启动. 其他容器一般都能这样
