Hello, please review the assigned task, since if the ubuntu_latest image does not exist, only ubuntu tag latest exists. Thank you very much for the tasks
Actually you don’t need to create a Dockerfile and build image from that file. You have to create a image from ubuntu_latest docker container.
If you will do "docker ps" , you get a list of docker containers.
Thank you very much, completely forgot to validate the docker that were running, regards.-
One of the Nautilus developer was working to test new changes on a container. He wants to keep a backup of his changes to the container. A new request has been raised for the DevOps team to create a new image from this container. Below are more details about it:
a. Create an image beta:nautilus on Application Server 2 from a container ubuntu_latest that is running on same server.
I have done the following:
[root@stapp02 steve]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
ubuntu latest e0f16e6366fe 4 weeks ago 78.1MB
[root@stapp02 steve]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
204c0a478c08 ubuntu "/bin/bash" About a minute ago Created ubuntu_latest
[root@stapp02 steve]# docker restart ubuntu_latest

I am getting the following error
Getting the following error while running docker start and restart command.
Also notice in the output of the docker ps -a command above the status of the container is “created”.
[root@stapp02 steve]# docker start ubuntu_latest
Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "proc" to rootfs at "/proc": mount src=proc, dst=/proc, dstFd=/proc/thread-self/fd/9, flags=0xe: no such file or directory: unknown
Error: failed to start containers: ubuntu_latest
Kindly help.
Thank You.
