Hi
How to mount a new volume to running container, that running container has already a existing volume.
is that possible to add

[@NextOpsVideos]

Unfortunately not possible.

[@HarikrishnaMuppa]

Hi Sir
Containers will have IP address or not ? Why i am asking to access the application also using the docker host and then application configured port.

[@NextOpsVideos]

In bridge scenario they get their own ports but ultimately they rely on docket host ip to handle traffic in any case.

[@tejakumargoud305]

Hi charan,

[root@ip-172-31-40-158 ~]# docker run it --name=srv01 --mount source=testvol01,destination=/data centos
Unable to find image 'it:latest' locally
docker: Error response from daemon: pull access denied for it, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.

[@NextOpsVideos]

It could be an issue connecting to dockerhub. Are you able to login successfully?

[@naren06938]

Any limit for docker volume size sir? Can I keep data 1GB or more in it and how can I share export this data or volume to my local Laptop or GitHub repo or S3 buckets?

[@NextOpsVideos]

Volume depends on your docker host storage. You can share the data with your docker host but not GitHub or s3

[@NextOpsVideos]

You can't rename any folder with in container

container create chesthunappudu kakunda , existing container ki volume attach cheyali ante ye command vaadali sir
existing volume and container ki multiple directories mount cheyali ante yela sir

[@NextOpsVideos]

Hi Mohan, thanks for watching.
You cannot add volume to a running container. If you want to add volume to an existing container first you need to commit the container using docker commit command which creates an image out of that container. Then you need to attach a volume while creating a new container from this new image.
