我目前有一个docker-compose.yml
文件,可以提供许多服务。这些服务之一是 pulsar,另一个是通过 websocket 连接的网络服务器。当我启动这些服务时,websocket 容器不起作用。它的日志说:Error Checking/Getting Partition Metadata while Subscribing on persistent://public/default/test
。我没有使用分区,所以我很难弄清楚这一点。
到目前为止,我已经做了很多谷歌搜索,发现这个问题没有答案,但看起来与我的问题相似。
这是我的docker-compose.yml
文件:
version: '3.2'
services:
pulsar:
image: apachepulsar/pulsar:latest
command: bin/pulsar standalone
ports:
- "6650"
- "8080"
ios_pos_ws_input:
depends_on:
- pulsar
environment:
- PULSAR_HOST=pulsar
image: dock.gastrofix.com/bridge/ios_pos_ws_input:${VERSION:-latest}
restart: always
ports:
- "8765"
command: python3 -m wait_for_pulsar "python3 -m inputs.ios_pos.web_sockets.ws_server"
ios_pos_ws_sink:
depends_on:
- pulsar
environment:
- PULSAR_HOST=pulsar
image: dock.gastrofix.com/bridge/ios_pos_ws_sink:${VERSION:-latest}
restart: always
ports:
- "8765"
command: python3 -m wait_for_pulsar "python3 -m sinks.ios_pos_ws"
volumes:
pulsar:
当我检查两者的日志时ios_pos_ws_input
,ios_pos_ws_sink
我看到了:
2019-05-15 14:12:52.809 INFO ClientConnection:300 | [172.28.0.5:53624 -> 172.28.0.2:6650] Connected to broker

我真的很想弄清楚这一点。我提前感谢任何帮助!

当客户端尝试使用命名空间时,它看起来似乎尚未创建。
我已经尝试使用这个简单的 compose 文件来放置更大的延迟,以确保在客户端启动时独立服务完全准备就绪:
version: '3.2'
services:
pulsar:
image: apachepulsar/pulsar:latest
command: bin/pulsar standalone
ports:
- "6650"
- "8080"
client:
depends_on:
- pulsar
image: apachepulsar/pulsar:latest
command: python -c "import pulsar, time; time.sleep(30); c = pulsar.Client('pulsar://pulsar:6650'); p = c.create_producer('my-topic')"
