Now, back on ubuntu-node01:Bring node02 in as a peer on node01’s weave network

weave connect ubuntu-node02

Starting with ubuntu-node01:Run a container detached on node01

docker container run -d --name app01 alpine tail -f /dev/null

Now, launch a container on ubuntu-node02: Run a container detached on node02

docker container run -d --name app02 alpine tail -f /dev/null

Since we are on node02, we will check there first…

From inside the app02 container running on node02,

let’s ping the app01 container running on node01

docker container exec -it app02 ping -c 4 app01

Similarly, from inside the app01 container running on node01,

let’s ping the app02 container running on node02

docker container exec -it app01 ping -c 4 app02
