Problems with data sync with CaaS

(Mastercatz) #1

docker swarm init

#docker service create -e DB_SERVER=xxx -e DB_USER=PrestaShop -e DB_PASSWD=PrestaShop -e DB_NAME=PrestaShop -e DB_PREFIX=ps --name externaldb-prestashop -p 8111:80 prestashop/prestashop

#docker swarm join \ --token xxx \

localhost# docker service ls

but the data does not seem to sync with the other nodes ?
ie) if I ssh in on the master and alter a file , the file does not change on the node

how can I go about having data redundancy ?
everytime I reboot a pc or stop a container I am back to stock image …
even when I try and backup a container I am back to defaullt image

#docker commit -p 78727078a04b container
#docker save -o ~/container.tar container
#docker load -i /root/container.tar

how can I keep data persistent and backed up on a remote location ?
