Ignite cache data is lost when docker container is restarted - ignite

Question

I want to enable persistence in ignite so that when ignite docker container is restarted or replaced with new version cache data is not lost.
I am using ignite 2.6.0. Here is the configuration file:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="ignite.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
<property name="dataStorageConfiguration">
<bean class="org.apache.ignite.configuration.DataStorageConfiguration">
<property name="defaultDataRegionConfiguration">
<bean class="org.apache.ignite.configuration.DataRegionConfiguration">
<property name="persistenceEnabled" value="true" />
</bean>
</property>
<property name="storagePath" value="/opt/ignite/apache-ignite-fabric/data/persistence" />
<property name="walPath" value="/opt/ignite/apache-ignite-fabric/data/wal" />
<property name="walArchivePath" value="/opt/ignite/apache-ignite-fabric/data/wal/archive" />
</bean>
</property>
<property name="discoverySpi">
<bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
<property name="ipFinder">
<bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.multicast.TcpDiscoveryMulticastIpFinder">
<property name="addresses">
<list>
<value>127.0.0.1:47500..47502</value>
</list>
</property>
</bean>
</property>
</bean>
</property>
</bean>
</beans>
I ran following command to deploy ignite docker container
sudo docker run -d -e "CONFIG_URI=" -e "OPTION_LIBS=ignite-core,ignite-spring,ignite-indexing,ignite-rest-http" -v /var/ignitedata:/opt/ignite/apache-ignite-fabric/data -p 9005:8080 --name=apacheignite apacheignite/ignite:2.6.0
I did not pass any value to CONFIG_URI is because i replace the default-config.xml file in the docker container.
I created a new cache using ignite rest api
http://localhost:9005/ignite?cmd=getorcreate&cacheName=myCache
Added sample values to cache
http://localhost:9005/ignite?cmd=put&key=10&val=2018-01-01&cacheName=myCache&keyType=int&valueType=date
I can retrieve the cache value
http://172.30.5.28:9005/ignite?cmd=get&key=10&cacheName=myCache&keyType=int&valueType=date
Now if i restart the docker container and try retrieving value, it does not return value
http://localhost:9005/ignite?cmd=get&key=10&cacheName=myCache&keyType=int&valueType=date
Has anyone seen this issue?
Thanks,
Rahul

Answer 1

Did you activate the cluster after you started it? When you use persistence, you need to tell Ignite how many nodes it should expect to see (called the "baseline").
You do that by running the control.sh script:
./control.sh --activate

Answer 2

You have to make sure that docker container still has same storage mounted, and also set consistentId to same value in configuration.
If you do that, cluster will auto-activate once all nodes have joined. You only have to activate it manually once.

Answer 3

Thank you Andrei Aleksandrov for pointing me to correct direction. I added working directory path and that helped in resolving the issue.
Posting the updated default-config.xml
