Then restart the service:
systemctl restart systemd-networkd
At this time, the ip address is allocated. It can be accessed through the Intranet.
3. Set host
Add a Host:First, enter the host IP address. If an error occurs, modify the IP address in the admin menu:Then add an agent that can be monitored by rancher only after the agent service is available.Of course, this host is itself.A super-long id will be generated a
The name of the container must be used to transfer files between the host and the container.
Get the method as follows:
1. First get the short ID of the container or the specified name.
2. Then, according to either of these two items to get the full name of the ID.
With this long ID, the file transfer between the machine and the
Well, I thought it would be easy to remove the image, but it's a little bit of a puzzle to start with. By deleting it, it was easy to find out. Share My experience:In two cases: to remove the image, first delete the container, delete the container, make sure the container is stopped, 2; the command to delete the container
Use Docker ps-a to view the ID of the container, as shown below
