Hi, mates. I am struggling to build a connection from a host machine(windows system) to a container(ubuntu). Running a command as following:
docker run --hostname=docker-desktop --env=DISPLAY=host.docker.internal:0.0 --env=PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin --volume=D:\humble_ws:/home/wc/humble_ws --network=host --restart=no --label='org.opencontainers.image.ref.name=ubuntu' --label='org.opencontainers.image.version=22.04' --runtime=runc -t -d 02d58a115dd9b508f1554bda8d7a33a59c9adcc559d810cc6d7692d51e0680c6
and then run into the container, I input “ifconfig” and got the following output:
# ifconfig

OK. Aboves are all the background. Now I am facing the following three problems, highly appreciate anyone could share any ideas to fix them out.
- when I try to ping the one of container such as IP:192.168.65.3 from the host machine, the
outputs are:
C:\Windows\system32>ping 192.168.65.3
Pinging 192.168.65.3 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
Ping statistics for 192.168.65.3:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
meaning " Request Timeout"。 So, how do I ping the container successfully?
-
I notice that there is a network name “services1” in the output of container network. what is that?
-
the docker desktop setting for docker subnetwork is 192.168.65.0/24. should I change to 192.168.31.0/24?
