## Docker image

If you are using a docker image, pull the new image:

Stop previous version and then run the new one:

docker run -i -t \
  -v ${PWD}/.volumes/council/cache:/council/cache/ \
  -p 3000:3000/tcp \
  -e PORT='3000' \
  -e LOG_LEVEL='debug' \
  -e LOG_FORMAT='simple' \
  -e RPC_URL='<rpc url>' \
  -e KAFKA_SSL='true' \
  -e KAFKA_SASL_MECHANISM='plain' \
  -e KAFKA_USERNAME='<kafka user>' \
  -e KAFKA_PASSWORD='<kafka password>' \
  -e KAFKA_BROKER_ADDRESS_1='<kafka address>' \
  -e KAFKA_TOPIC=defender \
  -e WALLET_PRIVATE_KEY \
  lidofinance/lido-council-daemon@sha256:679e171405b46335500796afbace495329d28879488ae255d8cb1270e56847f4

### Possible issue

We've updated dockerfile and now run the application as `node` user to restrict access rights.

This may cause a problem with accessing the old cache. If you see any problems accessing the cache files in the logs, delete the cache folder or the entire volume.

error: EACCES: permission denied, mkdir 'cache/chain-1'

### Envs

Please make sure that these variables are set correctly (creds for Kafka are the same as before):

RPC_URL=<mainnet RPC url>

KAFKA_USERNAME=<username>
KAFKA_PASSWORD=<password>

KAFKA_BROKER_ADDRESS_1=pkc-l7q2j.europe-north1.gcp.confluent.cloud:9092

WALLET_PRIVATE_KEY

The other ENV variables do not need to be changed, they should have default values:

PORT=3000
LOG_LEVEL=debug
LOG_FORMAT=json

PUBSUB_SERVICE=kafka
KAFKA_TOPIC=defender
KAFKA_SASL_MECHANISM=plain
KAFKA_SSL=true

The new version will reset the cache, the start will take about 30 minutes.
