I am a beginner to docker.Please correct me if anything wrong.
As shown in this docker swarm tutorial https://www.youtube.com/watch?v=nGSNULpHHZc , i am trying to setup multhost setup for my hyperledger fabric application.
I am using two oracle linux servers namely server 1 and server 2. I connected both the servers using the docker swarm as managers and created overlay network called my-net.
I followed the same syntax given in the above mentioned tutorial and created the service using the beolw mentioned syntax.
docker service create --name myservice --network my-net --replicas 2 alpine sleep 1d
As expected it created one conatianer in each the server. Say for example server 1 coantainer IP is 10.0.0.4 and server 2 container IP 10.0.0.5. Now, i am trying to ping from the second servers container to first server's container as shown below and it is pinging.
# docker exec -it ContainerID sh
/ # ping 10.0.0.4
PING 10.0.0.4 (10.0.0.4): 56 data bytes
64 bytes from 10.0.0.4: seq=0 ttl=64 time=0.082 ms
64 bytes from 10.0.0.4: seq=1 ttl=64 time=0.062 ms
64 bytes from 10.0.0.4: seq=2 ttl=64 time=0.067 ms
^C
--- 10.0.0.4 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 0.062/0.070/0.082 ms
Now, I am trying to create my service(1) using the beolw mentioned syntax.
docker service create --name myservice1 --network my-net --replicas 2 hyperledger/fabric-peer sleep 1d
As expected this also created one conatianer in each the server.
Say for example server 1 coantainer IP is 10.0.0.6 and server 2 container IP 10.0.0.7.
Now, I am trying to ping from the second servers container to first server's container as shown below.
This time i am getting ping not found error,
# docker exec -it ContainerID sh
# ping 10.0.0.6
sh: 1: ping: not found
Can anyone please help what is the problem with the second myservice1.
