Run the command: “docker start | privileged | label | memory | cpus | usb-mount”.
You can see the new image by running: “show docker images”. For example: docker commit my_name my_image my_version.
It is possible to reload the Docker images after upgrade with the command: docker load _.img.gz.The user is advised to execute the “no docker” command at some point in order to clear unused disk space.Rollbacking after running the “no docker” command may result in failure to create configured containers from unknown images. The “no docker” command erases all containers and images, including those that were reachable after rollback.The user can reach their old containers after a rollback procedure.The containers and docker images become inaccessible to the user (the docker process will not run).
To set the amount of memory allocated to the container, run the following command:ĭocker start imagename latestver containername init cpus 0.2 label new_label privileged sdk network Upgrade Ramifications Changing Docker Storage DriverĪs a result of the upgrade, the docker’s storage driver changes, which may cause a few additional changes: The Linux docker supports a hard limit to control memory resource allocation which limits the container to a given amount of user/system memory.
To ensure system stability and that no random process is killed to free up memory, it is strongly recommended that all resource configurations done in the container utilize OS user interfaces such as JSON/SNMP and take advantage of the internal loopback interface.
It is possible to configure multiple containers in dockers, however, they would compete for the same memory and compute resources allocated by the switch software (varies for different systems).
