Synology, Docker, Bitcoin node, exporter #32

Open shaltay74 opened 4 months ago

Hello. Sorry for my English, I'm using a translator. I'm working for Sinology, running a bitcoin node in docker (https://registry.hub.docker.com/r/lncm/bitcoind/) with your file: bitcoin.conf.

server=1 rpcauth=alice:8bfdd22c39bc8839b6c8e73659f4bbca$f46a37d99b29771a4b42dec9c7614dabe5400deff1ced0e98bb3d4aa643bed5e rpcbind=0.0.0.0 rpcport=8332 rpcallowip=0.0.0.0/0

rpcconnect=bitcoind rpcuser=alice rpcpassword=password=123&z!=@e

The node is working.

I'm running bitcoin-prometheus-exporter in Synology in docker with a slightly modified docker-compose.yml file:

ash-4.4# cat docker-compose.yml version: '3.3' services: exporter: container_name: bitcoin-exporter image: jvstein/bitcoin-prometheus-exporter:latest build: . ports:

what am I doing wrong?

If I go to the page: http://192.168.x.x:9332/metrics

shows: A server error occurred. Please contact the administrator.

You need to set the BITCOIN_RPC_HOST value to the host name or IP address of your bitcoin node.

Looking at your docker-compose.yml file, you are not running bitcoind as a service in the same compose file (i.e. this section). So, the hostname bitcoind provided by the docker-compose service will not be available.

How are you running bitcoind? Is it using a different docker-compose.yml file? If so, you may need to use a custom network to ensure the containers can talk to each other.

In what format should I write it BITCOIN_RPC_HOST?

BITCOIN_RPC_HOST: 192.168.1.10:8332

Yes I use docker-compose.yml for Bitcoin.

ash-4.4# cat docker-compose.yml version: '3' services: bitcoin: container_name: bitcoind user: 1000:1000 image: lncm/bitcoind:v27.0 volumes:

jvstein commented 4 months ago

Try setting to the IP address alone (e.g. BITCOIN_RPC_HOST: 192.168.1.10). The port is set via a different variable.

Something completely broke. )

log bitcoin-exporter:

log bitcoin-exporter:

2024/05/07 19:53:38 | stderr | 2024-05-07T14:53:38Z CRITICAL Received SIGTERM. Exiting.

That means that something is sending a SIGTERM signal to the exporter process. Nothing internal to the exporter will cause that. It's either docker stopping the container or something else.

shaltay74 commented 4 months ago

If I change from BITCOIN_RPC_HOST: bitcoind to BITCOIN_RPC_HOST: 192.168.x.x any other value, an error occurs.

If I open the page http://192.168.1.10:9332

Make sure you unset BITCOIN_CONF_PATH if you are using BITCOIN_RPC_HOST. The configuration file takes precedence.

Try setting LOG_LEVEL: "DEBUG" to get more log messages from the exporter.

I tried swapping the docker.io/lncm/bitcoind:v27.0 image into the the docker-compose.yml file in this repo. With that one line change (plus removing the first bitcoind command), everything seems to be working as expected.
