Posting this here as progress - i tested w/ 21.3.4:
version: '3.8'
services:
kafka-broker:

entrypoint: [/usr/bin/rpk, redpanda, start, --kafka-addr, "PLAINTEXT://0.0.0.0:29092,OUTSIDE://0.0.0.0:9092", --advertise-kafka-addr, "PLAINTEXT://kafka-broker:29092,OUTSIDE://localhost:9092"]
schema-registry:
image: confluentinc/cp-schema-registry:6.1.0
hostname: schema-registry
depends_on:
- kafka-broker
ports:
- 8081:8081
environment:
SCHEMA_REGISTRY_HOST_NAME: schema-registry
SCHEMA_REGISTRY_KAFKASTORE_BOOTSTRAP_SERVERS: kafka-broker:29092
and got:

thanks @raphaelauv for the report. We'll take a look. cc: @dotnwat

@raphaelauv thanks for the detailed report.
the good news is that this appears to be a networking issue. i was able to at least start the schema registry and get it connected to a redpanda instance not running inside docker:

there are two issues at play here
- we have an issue with ipv6 and how the broker is binding to its listening port.
- the redpanda broker inside docker appears to be advertising an empty host. @0x5d is working on this via #99
I'll update this ticket when we've resolved these issues.
In the mean time, I was able to get things working by running redpanda outside of docker, and then pointing the schema registery container at localhost via network_mode: host.
from redpanda.
@raphaelauv #100 just landed which fixes this issue.
from redpanda.
we should try this now that #25 and #126 merged.
from redpanda.
thanks @raphaelauv we'll update when its done. turned out to be more work than we anticipated, but i'd say early next week.
from redpanda.
Multiple listeners went in on #186 . Will tag here w/ release.
from redpanda.
We don't support env vars yet, so when you start Redpanda, you'll need to pass some command line flags:
You might be able to get away with:
redpanda start
--kafka-addr="$KAFKA_LISTENERS"
--advertise-kafka-addr="$KAFKA_ADVERTISED_LISTENERS"
from redpanda.
I've reopened #524
The easiest fix for now is to mount a configuration file that doesn't have kafka_api set:
./redpanda.yaml:
redpanda:
auto_create_topics_enabled: true
node_id: 1
rpk:
enable_usage_stats: true
chmod 777 ./redpanda.yaml
docker run --mount type=bind,source="$(pwd)"/redpanda.yaml,target=/etc/redpanda/redpanda.yaml vectorized/redpanda:v21.2.2 redpanda start --kafka-addr "PLAINTEXT://0.0.0.0:29092,OUTSIDE://0.0.0.0:9092" --advertise-kafka-addr "PLAINTEXT://kafka-broker:29092,OUTSIDE://localhost:9092"
from redpanda.
Just stumbled upon this issue while I was trying to set up containerized redpanda to be accessible to consumers on the local machine. For anyone who needs a temporary fix in docker-compose form, here it is (assuming you have the redpanda.yml
in the same directory as docker-compose.yml
and you've already done chmod 777 redpanda.yml
):
kafka:
image: 'vectorized/redpanda:latest'
command: [redpanda, start, --kafka-addr, "PLAINTEXT://0.0.0.0:9092,OUTSIDE://0.0.0.0:29092", --advertise-kafka-addr, "PLAINTEXT://kafka:9092,OUTSIDE://localhost:29092"]
ports:
- 9092:9092
- 29092:29092
volumes:
- type: bind
source: ./redpanda.yml
target: /etc/redpanda/redpanda.yaml
from redpanda.
@raphaelauv fixed in the latest release https://github.com/vectorizedio/redpanda/releases/latest
let us know if you run into issues again.
from redpanda.
Hi thanks for your reply.
I just tried by pulling the latest docker image and it's still not working , did you try my docker-compose example ? Thank you again
I tried with all theses different possibilities :
SCHEMA_REGISTRY_BOOTSTRAP_SERVERS: PLAINTEXT://kafka-broker:29092
SCHEMA_REGISTRY_BOOTSTRAP_SERVERS: kafka-broker:29092
SCHEMA_REGISTRY_KAFKASTORE_BOOTSTRAP_SERVERS: PLAINTEXT://kafka-broker:29092
SCHEMA_REGISTRY_KAFKASTORE_BOOTSTRAP_SERVERS: kafka-broker:29092
from redpanda.
@raphaelauv thanks for testing again! sorry, this ticket was closed too early.
there are a couple issues that we are working on to resolve this. first, we have a networking issue that is preventing the advertised server from being properly configured in this docker-compose scenario. follow #125 should be a pretty quick fix.
i was able to circumvent this with host-based networking as a quick test.
version: '3.8'
services:
kafka-broker:
image: vectorized/redpanda:latest
network_mode: host
ports:
- 9092:9092
schema-registry:
image: confluentinc/cp-schema-registry:6.0.0
network_mode: host
depends_on:
- kafka-broker
ports:
- 8081:8081
environment:
SCHEMA_REGISTRY_HOST_NAME: schema-registry
SCHEMA_REGISTRY_KAFKASTORE_BOOTSTRAP_SERVERS: localhost:9092
unfortunately the schema registry unearthed an issue with our fetch request compatibility. we have two pull request being tested right now that addresses this which you can follow here #25 and #126.
all these fixes should drop in the next day or two. i'll update this ticket then.
from redpanda.
I pulled the latest container for redpanda still the same error
from redpanda.
@raphaelauv can you use host networking as above?
We're still working on configuration via env vars.
I've raised an issue for supporting multiple listeners.
from redpanda.
Thank for the hack ( host networking ) but multiple listeners is a necessary feature for my kafka stack. I will wait until it's ready.
from redpanda.
Hi, I just tried my example ( from first post ) with the release v21.2.2 , it's not working
from redpanda.
@raphaelauv what @BenPope said :)
We have a few users using confluent schema registry successfully now:

@senior7515 thank you but I just copy paste your example on a new docker-compose.yml file and then "docker-compose up -d"

Looks like the configuraton didn't work:
kafka_api:
address: 0.0.0.0
port: 9092
Needs to be:
kafka_api:
- address: 0.0.0.0
name: plaintext
port: 29092
- address: 0.0.0.0
name: outside
port: 9092
from redpanda.
OK, so the problem is:
ERROR 2021/02/17 18:49:25 svType != tvType; key=kafka_api, st=[]interface {}, tt=map[string]interface {}, sv=[map[address:0.0.0.0 name:plaintext port:29092] map[address:0.0.0.0 name:outside port:9092]], tv=map[address:0.0.0.0 port:9092]
It looks like it tries to update the kafka_api
json node with a list, when it's already a map.
from redpanda.
For anyone who needs a temporary fix in docker-compose form, here it is (assuming you have the
redpanda.yml
in the same directory asdocker-compose.yml
and you've already donechmod 777 redpanda.yml
):
Looks great for a single broker, thanks for this.
One caveat: Looks like host networking is required for OUTSIDE, so won't work on MacOS.
from redpanda.
@0x5d can you close this ticket nwothat multiple listeners is in v21.3.5-beta3
from redpanda.
I also added a ticket + example of docker compose in here #931
from redpanda.
Hi There,
Need small help on configuring these values in helm
kafka_api:
- address: "0.0.0.0"
name: internal
port: 9092 - address: "0.0.0.0"
name: external
port: 9093
The default values.yaml doesn't contain internal. Kindly help in configuring the above values in helm chart.
