RE: Docker and clustering

[Aleksandr Pakhomov <ap...@gmail.com>]

Hi, could you please share the TCP/IP Discovery configuration? 

If you have not configured it please check this 
https://ignite.apache.org/docs/latest/clustering/tcp-ip-discovery <https://ignite.apache.org/docs/latest/clustering/tcp-ip-discovery>

Best regards,

> Hi,   I am trying to setup a two nodes replicated cluster, in an active/passive way.   On each node, a Java webapp will be accessing the local database instance using JDBC.   The app itself is stateless, but I need synced datas from the database.   Ignite seems to be a nice choice, as I don't need advanced SQL features but replication and simplicity.   So I am running an Ignite container on two differents hosts (10.17.10.55 and 10.17.10.56), using : docker run -v "/tmp/ignite.xml:/opt/ignite/apache-ignite/config/default-config.xml" -p "10800:10800" -p "11211:11211" -p "47100:47100" -p "47500:47500" -p "49112:49112" apacheignite/ignite:latest   And here is the content of the file "ignite.xml" (of course, "consistentId" value is different for each host, the rest is the same).

But the two Ignite instances don't seem to communicate, as I get an error message like :   Failed to connect to any address from IP finder (make sure IP finder addresses are correct and firewalls are disabled on all host machines): [/10.17.10.55:47500, /10.17.10.56:47500]   Did I miss something ? A quick and dirty try with a local docker-compose and a config file which is the base of the one I tried here was running flawlessly.   Regards
