I have two docker machines:
$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS redis-master * virtualbox Running tcp://192.168.99.100:2376 v1.10.1 redis-slave1 - virtualbox Running tcp://192.168.99.101:2376 v1.10.1
I am trying to deploy master/slave redis replication to those machines, so on each of them I run REDIS container + SENTINEL container and run
SLAVEOF command on master redis instance. Everything works fine at first, but after some time (1-2 minutes) master prints
# Connection with slave 192.168.99.101:6379 lost. message in log and slave logs
# Connection with master lost. and infinitely (without success) tries to resync with master.
REDIS version I use is
3.0.7 (also using sentinel shipped with redis).
Here is MASTER log (redis and sentinel logs): http://pastebin.com/raw/MvwCTeEu
Here is SLAVE log (redis and sentinel logs): http://pastebin.com/raw/vV6e3utK
port 26379 dir /tmp sentinel announce-ip <SENTINEL_IP> sentinel monitor mymaster <MASTER_IP> 6379 2 sentinel down-after-milliseconds mymaster 30000 sentinel parallel-syncs mymaster 1 sentinel failover-timeout mymaster 180000 sentinel announce-port 26379
redis.conf: http://pastebin.com/raw/dqFYzTwz (it's actually default REDIS config , except
repl-backlog-size which I've increased to
100mb to check if it wont help but it did not).
This is strange issue because at first replication/syncing works fine at first but, as I said, after 1-2 minutes master-slave connection is lost. During this time no redis/sentinel command are executed on any instance. I just start 4 containers and leave them for 1-2 minutes...
