$ docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world ca4f61b1923c: Pull complete Digest: sha256:ca0eeb6fb05351dfc8759c20733c91def84cb8007aa89a5bf606bc8b315b9fc7 Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. Start a Dockerized web server.

Like the hello-world image above, if the image is not found locally, Docker pulls it from Docker Hub. $ docker run -d -p 80:80 -name webserver nginx. In a web browser, go to to view the nginx homepage. Because we specified the default HTTP port, it isn’t necessary to append:80 at the end of the URL. Early beta releases used docker as the hostname to build the URL.

Now, ports are exposed on the private IP addresses of the VM and forwarded to localhost with no other host name set. View the details on the container while your web server is running (with docker container ls or docker ps): $ docker container ls CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 90 nginx 'nginx -g 'daemon off' About a minute ago Up About a minute 0.0.0.0:80-80/tcp, 443/tcp webserver. Stop and remove containers and images with the following commands. Use the “all” flag ( -all or -a) to view stopped containers. $ docker container ls $ docker container stop webserver $ docker container ls -a $ docker container rm webserver $ docker image ls $ docker image rm nginx Preferences menu Choose → Preferences from the menu bar and configure the runtime options described below. General General settings are:. Start Docker when you log in: Uncheck this option if you don’t want Docker to start when you open your session.

Automatically check for updates notifies you when an update is available. Click OK to accept and install updates (or cancel to keep the current version). If you disable this option, you can still find out about updates manually by choosing → Check for Updates. Include VM in Time Machine backups backs up the Docker for Mac virtual machine. (Disabled by default.). Securely store Docker logins in MacOS keychain stores your Docker login credentials. (Enabled by default.).

Send usage statistics — Send diagnostics, crash reports, and usage data to Docker. This information helps Docker improve the application and get more context for troubleshooting problems. (Enabled by default.) File sharing Choose which local directories to share with your containers. File sharing is required for volume mounting if the project lives outside of the /Users directory.

In that case, share the drive where the Dockerfile and volume are located. Otherwise, you get file not found or cannot start service errors at runtime. File share settings are:. Add a Directory: Click + and navigate to the directory you want to add.

Apply & Restart makes the directory available to containers using Docker’s bind mount ( -v) feature. There are some limitations on the directories that can be shared:. They cannot be a subdirectory of an already shared directory. They cannot already exist inside of Docker. For more information, see:. in the topic on.) Advanced On the Advanced tab, you can limit resources available to Docker.

Advanced settings are: CPUs: By default, Docker for Mac is set to use half the number of processors available on the host machine. To increase processing power, set this to a higher number; to decrease, lower the number.

Memory: By default, Docker for Mac is set to use 2 GB runtime memory, allocated from the total available memory on your Mac. To increase RAM, set this to a higher number; to decrease it, lower the number. Swap: Configure swap file size as needed.

The default is 1 GB. Disk Specify the Disk image location of the Linux volume, where containers and images are stored. You can also move the disk image location. If you attempt to move the disk image to a location that already has one, you get a prompt asking if you want to use the existing image or replace it.

Proxies Docker for Mac detects HTTP/HTTPS Proxy Settings from macOS and automatically propagates these to Docker and to your containers. For example, if you set your proxy settings to Docker uses this proxy when pulling containers. When you start a container, your proxy settings propagate into the containers. $ docker run -it alpine env PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin HOSTNAME=b7edf988b2b5 TERM=xterm HOME=/root HTTPPROXY=httpproxy=noproxy=.local, 169.254/16 You can see from the above output that the HTTPPROXY, httpproxy, and noproxy environment variables are set. When your proxy configuration changes, Docker restarts automatically to pick up the new settings. If you have containers that you wish to keep running across restarts, you should consider using.

Daemon You can configure options on the Docker daemon that determine how your containers run. Select Basic to configure the daemon with interactive settings, or select Advanced to edit the JSON directly. Experimental features Both Docker for Mac Stable and Edge releases have experimental features enabled on Docker Engine, as described.

If you uncheck experimental mode, Docker for Mac uses the current generally available release of Docker Engine. Don’t enable experimental features in production Experimental features are not appropriate for production environments or workloads. They are meant to be sandbox experiments for new ideas. Some experimental features may become incorporated into upcoming stable releases, but others may be modified or pulled from subsequent Edge releases, and never released on Stable.

You can see whether you are running experimental mode at the command line. If Experimental is true, then Docker is running in experimental mode, as shown here. (If false, Experimental mode is off.).

$ kubectl config get-contexts $ kubectl config use-context docker-for-desktop If you installed kubectl with Homebrew, or by some other method, and experience conflicts, remove /usr/local/bin/kubectl. To enable Kubernetes support and install a standalone instance of Kubernetes running as a Docker container, select Enable Kubernetes, choose the and click the Apply button. An Internet connection is required.

Images required to run the Kubernetes server are downloaded and instantiated as containers, and the /usr/local/bin/kubectl command is installed on your Mac. When Kubernetes is enabled and running, an additional status bar item displays at the bottom right of the Docker for Mac Preferences dialog. The status of Kubernetes shows in the Docker menu and the context points to docker-for-desktop. By default, Kubernetes containers are hidden from commands like docker service ls, because managing them manually is not supported. To make them visible, select Show system containers (advanced) and click Apply and restart. Most users do not need this option.

To disable Kubernetes support at any time, deselect Enable Kubernetes. The Kubernetes containers are stopped and removed, and the /usr/local/bin/kubectl command is removed.

For more about using the Kubernetes integration with Docker for Mac, see. Reset Select - Preferences from the menu bar, then click Reset to reset factory defaults, restart the Docker daemon, or uninstall. Reset settings are:. Restart - Select to restart the Docker daemon.

Remove all data - This option removes/resets all Docker data without a reset to factory defaults (which would cause you to lose settings). Reset to factory defaults - Choose this option to reset all options on Docker for Mac to its initial state, the same as when it was first installed. Uninstall - Choose this option to remove Docker for Mac from your system. Uninstall Docker for Mac from the commandline To uninstall Docker from Mac from a terminal, run: -uninstall. If your instance is installed in the default location, this command provides a clean uninstall. $ /Applications/Docker.app/Contents/MacOS/Docker -uninstall Docker is running, exiting. Docker uninstalled successfully.

You can move the Docker application to the trash. You might want to use the command-line uninstall if, for example, you find that the app is non-functional, and you cannot uninstall it from the menu. Add TLS certificates You can add trusted Certificate Authorities (CAs) (used to verify registry server certificates) and client certificates (used to authenticate to registries) to your Docker daemon. Add custom CA certificates (server side) All trusted CAs (root or intermediate) are supported.

Docker for Mac creates a certificate bundle of all user-trusted CAs based on the Mac Keychain, and appends it to Moby trusted certificates. So if an enterprise SSL certificate is trusted by the user on the host, it is trusted by Docker for Mac.

To manually add a custom, self-signed certificate, start by adding the certificate to the macOS keychain, which is picked up by Docker for Mac. Here is an example. $ security add-trusted-cert -d -r trustRoot -k /Library/Keychains/login.keychain ca.crt See also,. Note: You need to restart Docker for Mac after making any changes to the keychain or to the /.docker/certs.d directory in order for the changes to take effect. For a complete explanation of how to do this, see the blog post. Add client certificates You can put your client certificates in /.docker/certs.d/:/client.cert and /.docker/certs.d/:/client.key.

When the Docker for Mac application starts up, it copies the /.docker/certs.d folder on your Mac to the /etc/docker/certs.d directory on Moby (the Docker for Mac xhyve virtual machine). You need to restart Docker for Mac after making any changes to the keychain or to the /.docker/certs.d directory in order for the changes to take effect. The registry cannot be listed as an insecure registry (see ). Docker for Mac ignores certificates listed under insecure registries, and does not send client certificates.

Commands like docker run that attempt to pull from the registry produce error messages on the command line, as well as on the registry. Directory structures for certificates If you have this directory structure, you do not need to manually add the CA certificate to your Mac OS system login. /Users//.docker/certs.d/ └──: ├── client.cert └── client.key To learn more about how to install a CA root certificate for the registry and how to set the client TLS certificate for verification, see in the Docker Engine topics. Install shell completion Docker for Mac comes with scripts to enable completion for the docker, docker-machine, and docker-compose commands. The completion scripts may be found inside Docker.app, in the Contents/Resources/etc/ directory and can be installed both in Bash and Zsh. Bash Bash has To activate completion for Docker commands, these files need to be copied or symlinked to your bashcompletion.d/ directory.

For example, if you installed bash via. Etc =/Applications/Docker.app/Contents/Resources/etc ln -s $etc/docker.bash-completion $(brew -prefix )/etc/bashcompletion.d/docker ln -s $etc/docker-machine.bash-completion $(brew -prefix )/etc/bashcompletion.d/docker-machine ln -s $etc/docker-compose.bash-completion $(brew -prefix )/etc/bashcompletion.d/docker-compose Zsh In Zsh, the takes care of things. To activate completion for Docker commands, these files need to be copied or symlinked to your Zsh site-functions/ directory.

For example, if you installed Zsh via. Etc =/Applications/Docker.app/Contents/Resources/etc ln -s $etc/docker.zsh-completion /usr/local/share/zsh/site-functions/docker ln -s $etc/docker-machine.zsh-completion /usr/local/share/zsh/site-functions/docker-machine ln -s $etc/docker-compose.zsh-completion /usr/local/share/zsh/site-functions/docker-compose Give feedback and get help To get help from the community, review current user topics, join or start a discussion, log on to our.

Configure and troubleshoot the Docker daemon Estimated reading time: 11 minutes After successfully installing and starting Docker, the dockerd daemon runs with its default configuration. This topic shows how to customize the configuration, start the daemon manually, and troubleshoot and debug the daemon if you run into issues. Start the daemon using operating system utilities On a typical installation the Docker daemon is started by a system utility, not manually by a user. This makes it easier to automatically start Docker when the machine reboots. The command to start Docker depends on your operating system. Check the correct page under. Insurgency for mac. To configure Docker to start automatically at system boot, see.

Start the daemon manually If you don’t want to use a system utility to manage the Docker daemon, or just want to test things out, you can manually run it using the dockerd command. You may need to use sudo, depending on your operating system configuration.

When you start Docker this way, it runs in the foreground and sends its logs directly to your terminal. $ dockerd INFO0000 +job initnetworkdriver INFO0000 +job serveapi (unix:///var/run/docker.sock ) INFO0000 Listening for HTTP on unix (/var/run/docker.sock ) To stop Docker when you have started it manually, issue a Ctrl+C in your terminal. Configure the Docker daemon There are two ways to configure the Docker daemon:.

Use a JSON configuration file. This is the preferred option, since it keeps all configurations in a single place. Use flags when starting dockerd.

You can use both of these options together as long as you don’t specify the same option both as a flag and in the JSON file. If that happens, the Docker daemon won’t start and prints an error message. To configure the Docker daemon using a JSON file, create a file at /etc/docker/daemon.json on Linux systems, or C: ProgramData docker config daemon.json on Windows. Here’s what the configuration file looks like. Dockerd -help Many specific configuration options are discussed throughout the Docker documentation.

Some places to go next include:. Docker daemon directory The Docker daemon persists all data in a single directory. This tracks everything related to Docker, including containers, images, volumes, service definition, and secrets. By default this directory is:.

/var/lib/docker on Linux. C: ProgramData docker on Windows. You can configure the Docker daemon to use a different directory, using the data-root configuration option. Since the state of a Docker daemon is kept on this directory, make sure you use a dedicated directory for each daemon.

If two daemons share the same directory, for example, an NFS share, you are going to experience errors that are difficult to troubleshoot. Troubleshoot the daemon You can enable debugging on the daemon to learn about the runtime activity of the daemon and to aid in troubleshooting. If the daemon is completely non-responsive, you can also of all threads to be added to the daemon log by sending the SIGUSR signal to the Docker daemon. $ sudo kill -SIGHUP $(pidof dockerd ) On Windows hosts, restart Docker. Instead of following this procedure, you can also stop the Docker daemon and restart it manually with the debug flag -D. However, this may result in Docker restarting with a different environment than the one the hosts’ startup scripts create, and this may make debugging more difficult.

Force a stack trace to be logged If the daemon is unresponsive, you can force a full stack trace to be logged by sending a SIGUSR1 signal to the daemon. $ sudo kill -SIGUSR1 $(pidof dockerd ). Windows Server: Download. Run the executable with the flag -pid=.

This forces a stack trace to be logged but does not stop the daemon. Daemon logs show the stack trace or the path to a file containing the stack trace if it was logged to a file. The daemon continues operating after handling the SIGUSR1 signal and dumping the stack traces to the log. The stack traces can be used to determine the state of all goroutines and threads within the daemon. View stack traces The Docker daemon log can be viewed by using one of the following methods:. By running journalctl -u docker.service on Linux systems using systemctl.

/var/log/messages, /var/log/daemon.log, or /var/log/docker.log on older Linux systems. By running Get-EventLog -LogName Application -Source Docker -After (Get-Date).AddMinutes(-5) Sort-Object Time Export-CSV /last5minutes.CSV on Docker EE for Windows Server Note: It is not possible to manually generate a stack trace on Docker for Mac or Docker for Windows. However, you can click the Docker taskbar icon and choose Diagnose and feedback to send information to Docker if you run into issues. Look in the Docker logs for a message like the following.goroutine stacks written to /var/run/docker/goroutine-stacks-2017-36z.log.daemon datastructure dump written to /var/run/docker/daemon-data-2017-36z.log The locations where Docker saves these stack traces and dumps depends on your operating system and configuration. You can sometimes get useful diagnostic information straight from the stack traces and dumps. Otherwise, you can provide this information to Docker for help diagnosing the problem.

Check whether Docker is running The operating-system independent way to check whether Docker is running is to ask Docker, using the docker info command. You can also use operating system utilities, such as sudo systemctl is-active docker or sudo status docker or sudo service docker status, or checking the service status using Windows utilities.

Finally, you can check in the process list for the dockerd process, using commands like ps or top.,.
