Some best practices in Docker usage

This article will record:

• Best practices that are organized in the process of using Docker.
• Other Docker user-published (possibly translated, all with original links) validated best practices.

Therefore, this article will be updated for a long time.

Docker Installation Related

If you use Docker after the installation is complete, the following error occurs:

> Cannot connect to the Docker daemon. Is 'docker -d' running on this host?

Referring to the content here, we need to execute the following command to install AppArmor:

sudo apt-get install apparmor

Docker Usage Related

• Using Bash Aliases to simplify Docker use commands, inspired by a great article (the site that publishes this article docker.cn is also a good Docker resource station), I've expanded:

Add the following content to the $HOME/.bash_aliases:

# Show all available docker related aliases.aliasdockeraliases=' printf ' \nbelow is all pre-defined docker maintainance Aliases:\n\ndkka | Dockerkillall\tkill All running Containers\ndksa | Dockerstopall\tstop All running CONTAINERS\NDKRC | Dockerremovec\tremove All stopped Containers\ndkri | Dockerremovei\tremove All untagged Images\ndkra | Dockerremovea\tremove all stopped containers and untagged images\n\n "'aliasDkas=' printf ' \nbelow is all pre-defined docker maintainance Aliases:\n\ndkka | Dockerkillall\tkill All running Containers\ndksa | Dockerstopall\tstop All running CONTAINERS\NDKRC | Dockerremovec\tremove All stopped Containers\ndkri | Dockerremovei\tremove All untagged Images\ndkra | Dockerremovea\tremove all stopped containers and untagged images\n\n "' # Kill all running containers.aliasDockerkillall=' printf ' \n>>> killing all running containers\n\n "&& Docker Kill $ (Docker ps-q) && printf" \ n "'aliasDkka=' printf ' \n>>> killing all running containers\n\n "&& Docker Kill $ (Docker ps-q) && printf" \ n "' # Stop all running containers.aliasDockerstopall=' printf ' \n>>> stopping all running containers\n\n "&& Docker stop $ (Docker ps-q) && printf "\ n" 'aliasDksa=' printf ' \n>>> stopping all running containers\n\n "&& Docker stop $ (Docker ps-q) && printf "\ n" ' # Remove all stopped containers.aliasDockerremovec=' printf ' \n>>> removing stopped containers\n\n "&& Docker RM $ (Docker ps-a-Q) && printf" \ n "'aliasDKRC=' printf ' \n>>> removing stopped containers\n\n "&& Docker RM $ (Docker ps-a-Q) && printf" \ n "' # Remove all untagged images.aliasDockerremovei=' printf ' \n>>> removing untagged images\n\n ' && Docker RMI $ (Docker images-q-F dangling=true) & & printf "\ n" 'aliasDkri=' printf ' \n>>> removing untagged images\n\n ' && Docker RMI $ (Docker images-q-F dangling=true) & & printf "\ n" ' # Remove All stopped containers and untagged images.aliasDockerremovea=' Dockerremovec | | true && dockerremovei 'aliasDkra=' Dockerremovec | | true && dockerremovei '

You can then use these aliases by executing "source ~/.bash_aliases" on the command line, such as:

$ dkasBelow are all pre-defined docker maintainance aliases:dkka | dockerkillall    Kill all running containersdksa | dockerstopall    Stop all running containersdkrc | dockerremovec    Remove all stopped containersdkri | dockerremovei    Remove all untagged imagesdkra | dockerremovea    Remove all stopped containers and untagged images
