I am using the official apache/rocketmq-docker docker-compose.yml and was wondering why there is always one port missing in the subsequent order?
In broker is port 10910 missing.
broker:
image: apacherocketmq/rocketmq:ROCKETMQ_VERSION
container_name: rmqbroker
links:
- namesrv
ports:
- 10909:10909
- 10911:10911
- 10912:10912
In broker1 is port 10930 missing
broker1:
image: apacherocketmq/rocketmq:ROCKETMQ_VERSION
container_name: rmqbroker-b
links:
- namesrv
ports:
- 10929:10909
- 10931:10911
- 10932:10912
And why do we actually need three ports for each broker? In some projects I found, they only use one port each. I couldn't find anything in the official Apache RocketMQ Documentation or on Github.

I'm a little bit confused. I've been following this to get started and the installation method.
https://aws.amazon.com/premiumsupport/knowledge-center/kinesis-kafka-connector-msk/
Setup AWS cli and configure it
Install maven
Compile connector
Set classpath with the jar generated
Set up the properties file of the connector
FYI: I have a docker-compose that creates all my containers (kafka, mqtt, etc.)
(all of the above is setup on-premise)
And then, I executed all this on my machine itself and not on the Kafka container, so for the last step how would that work when I try to run it standalone?

I guess I have to go into my Kafka container and run the below code, but how can I reference by machine path... I'm stuck here or perhaps I'm missing something:
./bin/connect-standalone.sh {{path_from_machine_where_jar_is}}/kinesis-kafka-connector/config/worker.properties {{path_from_machine_where_jar_is}}/kinesis-kafka-connector/config/kinesis-streams-kafka-
connector.properties
Or I have to run all the previous steps in my Kafka container directly...
I was thinking of just doing this, copy my jar file and just moving it in my kafka container.
docker cp /hostfile (container_id):/(to_the_place_you_want_the_file_to_be)
Thank you!
guess I have to go into my Kafka container and run the below code
No. Containers should only run one process, which is kafka server.
So, either you download Kafka locally and run the Connect scripts from your host.
Or you simply add a new container for Kafka Connect, which will run Connect distributed mode, rather than standalone.
In either case, yes, you need to copy (or mount) the jar into Connect's plugin path
Alternatively, run MSK rather than Kinesis and produce your Kafka data there rather than locally.
Cheers
I am currently trying to reproduce the tutorial to develop an application / solution with Fiware seen in: Desarrolla tu primer aplicación en Fiware and I am having difficulty connecting Grafana with the Crate database (recommended by Fiware).
My docker-compose file configuration is:

After starting the containers, I have a positive response from OCB (Orion), from Quantumleap and even after creating the subscription between Orion and quantumleap, in the Crate database, the data is stored and updated correctly.
Unfortunately I am not able to get the visualization of the data in grafana.
I thought that the reason was the fact that crateDB was removed as a grafana plugin versions ago, but after researching how to connect crateDB with grafana, through a postgres data source (I read on: Visualizing time series data with Grafana and CrateDB), I'm still having difficulty getting the connection, getting in grafana "Query error
dbquery error: EOF"
grafana settings img
The difference with respect to the guide is the listening port, since with input port 5432 I get a response indicating that it is not possible to connect to the server. I'm using port 4300.
After configuring, and trying to query from grafana, I get the mentioned EOF error
EOF error in grafana img
I tried to connect from a database IDE (Dbeaver) and I get exactly the same problem.
EOF error in Dbeaver img
Is there something I am missing?
What should I change in my docker configuration, or ports, or anything else to fix this?
I think it is worth mentioning that I am studying this because I am being asked in a project to visualize context switches in real time with Fiware and grafana.
Thanks in advance
The PostgreSQL port 5432 must be exposed as well by the CrateDB docker image.
Additionally, I highly recommend to use a recent (or just the latest) CrateDB version, current stable is 5.0.0, your used version 1.0.5 is very old and not maintained anymore.
Full example entry:

I want to use the fluent-bit docker image to help me persist the ephemeral docker container logs to a location on my host (and later use it to ship logs elsewhere).
I am facing issues such as:
Cannot start service clamav: failed to initialize logging driver: dial tcp 127.0.0.1:24224: connect: connection refused
I have read a number of post including
configuring fluentbit with docker but I'm still at a lost.
My docker-compose is made up of nginx, our app, keycloak, elasticsearch and clamav. I have added fluent-bit, made it first to starts via depends on. I changed the other services to use the fluentd logging driver.
Part of config:
clamav:
container_name: clamav-app
image: tiredofit/clamav:latest
restart: always
volumes:
- ./clamav/data:/data
- ./clamav/logs:/logs
environment:
- ZABBIX_HOSTNAME=clamav-app
- DEFINITIONS_UPDATE_FREQUENCY=60
networks:
- iris-network
expose:
- "3310"
depends_on:
- fluentbit
logging:
driver: fluentd
fluentbit:
container_name: iris-fluent
image: fluent/fluent-bit:latest
restart: always
networks:
- iris-network
volumes:
- ./fluent-bit/etc:/fluent-bit/etc
ports:
- "24224:24224"
- "24224:24224/udp"
I have tried to proxy_pass 24224 to fluentbit in nginx and start nginx first, and that avoided the error on clamav and es, but same error with keycloak.
So how can I configure the service to use the host or is it that localhost is not the "external" host?
So I have the following docker-compose.yml
version: "3.7"

Spring boot starts up fine and can connect to mysql.
When I connect to http://api-dev.roundclinic.app:8080/../ I can hit my application just fine
When I connect to http://api-dev.roundclinic.app/../ I get a gateway timeout. I can see in the traefik logs that it's forwarding the request to what seems to be the correct IP and port, but nothing hits the actual application. I'm not sure what's going on here. Any help?
When accessing port 8080 you are bypassing Traefik and directly access your application, correct?
Generally speaking the Traefik labels look good. Entrypoint, Port and Host are defined, router and service port are present. These are usually all the requirements for Docker-based setups.
One thing that I noticed is that the traefik container uses "traefik.docker.network=traefik-network", but your web app uses:
"--providers.docker.network=traefik_default".
I am not sure if traefik_default is something that traefik provides but that mismatch in network names might be the issue.
I can't test if that is the problem but that would be the first thing to check.
One way would be to simplify your config but just always using the networks key from docker compose instead of mixing it with labels and arguments.
I have a series of containers that are started by docker-compose. Specifically they are multiple zookeeper containers:
zk1:
image: seven10/zookeeper:3.4.6
container_name: zk1
hostname: zk1
restart: always
ports:
- "2181:2181"
- "2888:2888"
- "3888:3888"
environment:
- ZOOKEEPER_ID=1
net: ${MY_NETWORK_NAME}
volumes:
- /seven10/zk/zk1/data:/opt/zookeeper-3.4.6/data
zk2:
image: seven10/zookeeper:3.4.6
container_name: zk2
restart: always
hostname: zk2
ports:
- "2182:2181"
- "2889:2888"
- "3889:3888"
environment:
- ZOOKEEPER_ID=2
net: ${MY_NETWORK_NAME}
volumes:
- /seven10/zk/zk2/data:/opt/zookeeper-3.4.6/data
zk3:
image: seven10/zookeeper:3.4.6
container_name: zk3
hostname: zk3
restart: always
ports:
- "2183:2181"
- "2890:2888"
- "3890:3888"
environment:
- ZOOKEEPER_ID=3
net: ${MY_NETWORK_NAME}
volumes:
- /seven10/zk/zk3/data:/opt/zookeeper-3.4.6/data
So when I go to start the containers, zk1 gives me this warning at the start:
WARN [WorkerSender[myid=1]:QuorumCnxManager#382] - Cannot open channel to 3 at
election address zk3:3888
java.net.UnknownHostException: zk3
but then doesn't say anything else about zk3 after a couple of seconds.
However, zk1 gives the following error for zk2 continuously:
2016-02-18 15:28:57,384 [myid:1] - WARN [QuorumPeer[myid=1]/0:0:0:0:0:0:0:0:2181:Learner#233] - Unexpected exception, tries=0, connecting to zk2:2888
java.net.UnknownHostException: zk2
zk2 doesn't say ANYTHING ever about zk1, but briefly complains with the "cannot open channel" error for zk3.
zk3 doesn't every mention zk1 or zk2.
So the big problem is that zk1 can't find zk2 ever. It just spams the logs and refuses connections from kafka. Why is this so and how should I go about solving this problem?
My dev box is using docker version 1.9.1 and docker-compose version 1.5.1 on ubuntu 14.04 (Mint Rafello I think?), although the target environment will be ubuntu 15.10.
Does your host system know how to link zk1/2/3 to an IP address? If you're launching all three servers on the same node, you should use localhost as the host name (the server name should still be unique)
