The documentation around CONFIG_INI says "The downloaded config file will be saved to ./ignite-config.xml", except that did not happen. Therefore when I started visor, I had no way to discover the cluster, so visor created a new one. After much newbie confusion, I copied the config file from the URL into my docker container, and visor found it, and I could open it, and then did meaningful things.
I'm using only S3 discovery for the cluster, and visor needed a copy of this to discover the cluster. <property name="discoverySpi"> <bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi"> <property name="ipFinder"> <bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.s3.TcpDiscoveryS3IpFinder"> The visor instructions simply say read the help, and if you type help, it provides a command list. Notably, the Description of the help command doesn't indicate it takes arguments. An indication that "help open" was something I could/should type would have been useful. This was like discovering that I can kill the dragon with my bare hands. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
