Nervos CKB miner unable to find job on connection: getLatestStratumJobEx fail about btcpool-abandoned HOT 7 CLOSED

How to configure ckb mining pool, please see this issue: #378
have you started ckb-nodebridge to get work from ckb-node?

from btcpool-abandoned.

Nodebridge is up and creating RawJobs for kafka:
/usr/bin/nodebridge ckb --db_url mysql://root:root@mysql:3306/BTCPOOL_CKB --job_topic CkbRawGw --kafka_brokers "kafka:19092" --rpc_addr http://ckb-node:8114 --rpc_interval "2000" --solved_share_topic CkbSolvedShare

However, I am still getting the same error. When connecting a miner.

It seems these are the two places in the code where it is throwing errors:

src/StratumServer.cc:185

src/ckb/StratumSessionCkb.cc:62

from btcpool-abandoned.

it means that the sserver didn't get job from Kafka, you should check whether your jobmaker have received job and sent job to kafka or not.

Nodebridge is sending messages to Kafka, here is the kafka dashboard output:

Is this the right topic?

No other topics are being populated by nodebridge, only CKBRawGw. When switching the nodebridge's --job_topic from CKBRawGw to CKBJob, I get a parsing error from BTCPool.

Here is my job_workers config:

We've updated our repo so we can recreate this error more reliably with docker-compose:

https://github.com/insight-nervos/btcpool-docker-compose#local-miner

To get the docker-compose up and running with the test miner use this command:

docker-compose -f docker-compose.yml -f docker-compose.override.ckb-miner.yml up -d

Wait at least 30 seconds for all of the applications to come up and running

To make sure the miner is running, use this command:

docker-compose -f docker-compose.yml -f docker-compose.override.ckb-miner.yml logs ckb-miner

The expected output is:

To find the error in the btcpool logs, use this command:

docker-compose -f docker-compose.yml -f docker-compose.override.ckb-miner.yml logs btcpool

The expected output is:

The main docker compose file is here: ./docker-compose.yml

The btcpool config is located here: ./btcpool/config/sserver.cfg.

Again thank you so much for your time, any help on this issue would be greatly appreciated.

btcpool-ckb must Contain the following components:
1)， nodebridge get rawjob from ckb-node and send rawjob to CkbRawGw,you can start it with the following command:
./nodebridge ckb --db_url mysql://useername:[email protected]:3306/bpool_local_db --job_topic CkbRawGw --kafka_brokers "127.0.0.1:9092" --rpc_addr http://127.0.0.1:8114 --rpc_interval "2000" --solved_share_topic CkbSolvedShare
2),，jobmaker get raw job from CkbRawGw and check the data and remove the duplicate, and then send job to CkbJob topic .
3),，sserver get job from CkbJob , and then send job to ckbminer, and when ckbminer submited a solved share ,sserver will send this share to solved_share_topic .
the cfg of jobmaker and sserver, you can find it in ckb-cfg

Looks like I was missing the jobmaker program in the docker-compose. Thank you!
