.SH DESCRIPTION
|
||||||
|
If you \fBdocker run\fR a container in detached mode (\fB-d\fR), you can reattach to the detached container with \fBdocker attach\fR using the container's ID or name.
|
||||||
|
.sp
|
||||||
|
You can detach from the container again (and leave it running) with CTRL-c (for a quiet exit) or CTRL-\ to get a stacktrace of the Docker client when it quits. When you detach from the container the exit code will be returned to the client.
|
||||||
|

.SH DESCRIPTION
|
||||||
|
This will read the Dockerfile from the directory specified in \fBPATH\fR. It also sends any other files and directories found in the current directory to the Docker daemon. The contents of this directory would be used by ADD command found within the Dockerfile.
|
||||||
|
Warning, this will send a lot of data to the Docker daemon if the current directory contains a lot of data.
|
||||||
|
If the absolute path is provided instead of ‘.’, only the files and directories required by the ADD commands from the Dockerfile will be added to the context and transferred to the Docker daemon.
|
||||||
|
.sp
|
||||||
|
When a single Dockerfile is given as URL, then no context is set. When a Git repository is set as URL, the repository is used as context.

.B Building an image from current directory
|
||||||
|
.TP
|
||||||
|
USing a Dockerfile, Docker images are built using the build command:
|
||||||
|
.sp
|
||||||
|
.RS
|
||||||
|
docker build .
|
||||||
|
.RE
|
||||||
|
.sp
|
||||||
|
If, for some reasone, you do not what to remove the intermediate containers created during the build you must set--rm=false.
|
||||||
|
.sp
|
||||||
|
.RS
|
||||||
|
docker build --rm=false .
|
||||||
|
.sp
|
||||||
|
.RE
|
||||||
|
.sp
|
||||||
|
A good practice is to make a subdirectory with a related name and create the Dockerfile in that directory. E.g. a directory called mongo may contain a Dockerfile for a MongoDB image, or a directory called httpd may contain an Dockerfile for an Apache web server.
|
||||||
|
.sp
|
||||||
|
It is also good practice to add the files required for the image to the subdirectory. These files will be then specified with the `ADD` instruction in the Dockerfile. Note: if you include a tar file, which is good practice, then Docker will automatically extract the contents of the tar file specified in the `ADD` instruction into the specified target.
|
||||||
|
.sp
|
||||||
|
.B Building an image container using a URL
|
||||||

.TP
|

This will clone the Github repository and use it as context. The Dockerfile at the root of the repository is used as Dockerfile. This only works if the Github repository is a dedicated repository. Note that you can specify an arbitrary Git repository by using the ‘git://’ schema.

.SH DESCRIPTION
|
||||||
|
This command lists the images stored in the local Docker repository.
|
||||||
|
.sp
|
||||||
|
By default, intermediate images, used during builds, are not listed. Some of the output, e.g. image ID, is truncated, for space reasons. However the truncated image ID, and often the first few characters, are enough to be used in other Docker commands that use the image ID. The output includes repository, tag, image ID, date created and the virtual size.
|
||||||
|
.sp
|
||||||
|
The title REPOSITORY for the first title may seem confusing. It is essentially the image name. However, because you can tag a specific image, and multiple tags (image instances) can be associated with a single name, the name is really a repository for all tagged images of the same name.

.TP
|

.B -t, --tree=\fItrue\fR|\fIfalse\fR:

This displays a staggered hierarchy tree where the less indented image is the oldest with dependent image layers branching inward (to the right) on subsequent lines. The newest or top level image layer is listed last in any tree branch.

IMAGE [COMMAND] [ARG...]
|

|
.SH DESCRIPTION
|
||||||
|
.PP
|
||||||
|
Run a process in a new container. \fBdocker run\fR starts a process with its own file system, its own networking, and its own isolated process tree. The \fIIMAGE\fR which starts the process may define defaults related to the process that will be run in the container, the networking to expose, and more, but \fBdocker run\fR gives final control to the operator or administrator who starts the container from the image. For that reason \fBdocker run\fR has more options than any other docker command.
|
||||||
|
|
||||||
|
If the \fIIMAGE\fR is not already loaded then \fBdocker run\fR will pull the \fIIMAGE\fR, and all image dependencies, from the repository in the same way running \fBdocker pull\fR \fIIMAGE\fR, before it starts the container from that image.
|
||||||
|
|
||||||

.SH "OPTIONS"
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B -a, --attach=\fIstdin\fR|\fIstdout\fR|\fIstderr\fR:
|
||||||
|
Attach to stdin, stdout or stderr. In foreground mode (the default when -d is not specified), \fBdocker run\fR can start the process in the container and attach the console to the process’s standard input, output, and standard error. It can even pretend to be a TTY (this is what most commandline executables expect) and pass along signals. The \fB-a\fR option can be set for each of stdin, stdout, and stderr.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B -c, --cpu-shares=0:
|
||||||
|
CPU shares in relative weight. You can increase the priority of a container with the -c option. By default, all containers run at the same priority and get the same proportion of CPU cycles, but you can tell the kernel to give more shares of CPU time to one or more containers when you start them via \fBdocker run\fR.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B -m, --memory=\fImemory-limit\fR:
|
||||||
|
Allows you to constrain the memory available to a container. If the host supports swap memory, then the -m memory setting can be larger than physical RAM. The memory limit format: <number><optional unit>, where unit = b, k, m or g.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B --cidfile=\fIfile\fR:
|
||||||
|
Write the container ID to the file specified.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B -d, --detach=\fItrue\fR|\fIfalse\fR:
|
||||||
|
Detached mode. This runs the container in the background. It outputs the new container's id and and error messages. At any time you can run \fBdocker ps\fR in the other shell to view a list of the running containers. You can reattach to a detached container with \fBdocker attach\fR. If you choose to run a container in the detached mode, then you cannot use the -rm option.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B --dns=\fIIP-address\fR:
|
||||||
|
Set custom DNS servers. This option can be used to override the DNS configuration passed to the container. Typically this is necessary when the host DNS configuration is invalid for the container (eg. 127.0.0.1). When this is the case the \fB-dns\fR flags is necessary for every run.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B -e, --env=\fIenvironment\fR:
|
||||||
|
Set environment variables. This option allows you to specify arbitrary environment variables that are available for the process that will be launched inside of the container.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B --entrypoint=\ficommand\fR:
|
||||||
|
This option allows you to overwrite the default entrypoint of the image that is set in the Dockerfile. The ENTRYPOINT of an image is similar to a COMMAND because it specifies what executable to run when the container starts, but it is (purposely) more difficult to override. The ENTRYPOINT gives a container its default nature or behavior, so that when you set an ENTRYPOINT you can run the container as if it were that binary, complete with default options, and you can pass in more options via the COMMAND. But, sometimes an operator may want to run something else inside the container, so you can override the default ENTRYPOINT at runtime by using a \fB--entrypoint\fR and a string to specify the new ENTRYPOINT.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B --expose=\fIport\fR:
|
||||||
|
Expose a port from the container without publishing it to your host. A containers port can be exposed to other containers in three ways: 1) The developer can expose the port using the EXPOSE parameter of the Dockerfile, 2) the operator can use the \fB--expose\fR option with \fBdocker run\fR, or 3) the container can be started with the \fB--link\fR.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B -P, --publish-all=\fItrue\fR|\fIfalse\fR:
|
||||||
|
When set to true publish all exposed ports to the host interfaces. The default is false. If the operator uses -P (or -p) then Docker will make the exposed port accessible on the host and the ports will be available to any client that can reach the host. To find the map between the host ports and the exposed ports, use \fBdocker port\fR.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B -p, --publish=[]:
|
||||||
|
Publish a container's port to the host (format: ip:hostPort:containerPort | ip::containerPort | hostPort:containerPort) (use 'docker port' to see the actual mapping)
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B -h , --hostname=\fIhostname\fR:
|
||||||
|
Sets the container host name that is available inside the container.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B -i , --interactive=\fItrue\fR|\fIfalse\fR:
|
||||||
|
When set to true, keep stdin open even if not attached. The default is false.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B --link=\fIname\fR:\fIalias\fR:
|
||||||
|
Add link to another container. The format is name:alias. If the operator uses \fB--link\fR when starting the new client container, then the client container can access the exposed port via a private networking interface. Docker will set some environment variables in the client container to help indicate which interface and port to use.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B -n, --networking=\fItrue\fR|\fIfalse\fR:
|
||||||
|
By default, all containers have networking enabled (true) and can make outgoing connections. The operator can disable networking with \fB--networking\fR to false. This disables all incoming and outgoing networking. In cases like this, I/O can only be performed through files or by using STDIN/STDOUT.
|
||||||
|
|
||||||
|
Also by default, the container will use the same DNS servers as the host. but you canThe operator may override this with \fB-dns\fR.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B --name=\fIname\fR:
|
||||||
|
Assign a name to the container. The operator can identify a container in three ways:
|
||||||
|
.sp
|
||||||
|
.nf
|
||||||
|
UUID long identifier (“f78375b1c487e03c9438c729345e54db9d20cfa2ac1fc3494b6eb60872e74778”)

The UUID identifiers come from the Docker daemon, and if a name is not assigned to the container with \fB--name\fR then the daemon will also generate a random string name. The name is useful when defining links (see \fB--link\fR) (or any other place you need to identify a container). This works for both background and foreground Docker containers.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B --privileged=\fItrue\fR|\fIfalse\fR:
|
||||||
|
Give extended privileges to this container. By default, Docker containers are “unprivileged” (=false) and cannot, for example, run a Docker daemon inside the Docker container. This is because by default a container is not allowed to access any devices. A “privileged” container is given access to all devices.
|
||||||
|
|
||||||
|
When the operator executes \fBdocker run -privileged\fR, Docker will enable access to all devices on the host as well as set some configuration in AppArmor (\fB???\fR) to allow the container nearly all the same access to the host as processes running outside of a container on the host.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B --rm=\fItrue\fR|\fIfalse\fR:
|
||||||
|
If set to \fItrue\fR the container is automatically removed when it exits. The default is \fIfalse\fR. This option is incompatible with \fB-d\fR.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B --sig-proxy=\fItrue\fR|\fIfalse\fR:
|
||||||
|
When set to true, proxify all received signals to the process (even in non-tty mode). The default is true.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B -t, --tty=\fItrue\fR|\fIfalse\fR:
|
||||||
|
When set to true Docker can allocate a pseudo-tty and attach to the standard input of any container. This can be used, for example, to run a throwaway interactive shell. The default is value is false.
|
||||||

|
.TP
|
||||||
|
.B -v, --volume=\fIvolume\fR:
|
||||||
|
Bind mount a volume to the container. The \fB-v\fR option can be used one or more times to add one or more mounts to a container. These mounts can then be used in other containers using the \fB--volumes-from\fR option. See examples.
|
||||||
|
|
||||||
|
.TP
|
||||||
|
.B --volumes-from=\fIcontainer-id\fR:
|
||||||
|
Will mount volumes from the specified container identified by container-id. Once a volume is mounted in a one container it can be shared with other containers using the \fB--volumes-from\fR option when running those other containers. The volumes can be shared even if the original container with the mount is not running.
|
||||||
|
|
||||||
|
.TP
|
||||||

.B -w, --workdir=\fIdirectory\fR:
|

Working directory inside the container. The default working directory for running binaries within a container is the root directory (/). The developer can set a different default with the Dockerfile WORKDIR instruction. The operator can override the working directory by using the \fB-w\fR option.

If you want messages that are logged in your container to show up in the host's syslog/journal then you should bind mount the /var/log directory as follows.
|

.B Linking Containers
|
||||||
|
.TP
|
||||||
|
The link feature allows multiple containers to communicate with each other. For example, a container whose Dockerfile has exposed port 80 can be run and named as follows:
|
||||||
|
.sp
|
||||||
|
.RS
|
||||||
|
docker run --name=link-test -d -i -t fedora/httpd
|
||||||
|
.RE
|
||||||
|
.sp
|
||||||
|
.TP
|
||||||
|
A second container, in this case called linker, can communicate with the httpd container, named link-test, by running with the \fB--link=<name>:<alias>\fR
|
||||||
|
.sp
|
||||||
|
.RS
|
||||||
|
docker run -t -i --link=link-test:lt --name=linker fedora /bin/bash
|
||||||
|
.RE
|
||||||
|
.sp
|
||||||
|
.TP
|
||||||
|
Now the container linker is linked to container link-test with the alias lt. Running the \fBenv\fR command in the linker container shows environment variables with the LT (alias) context (\fBLT_\fR)
|
||||||

.sp
|

.B Mapping Ports for External Usage

The exposed port of an application can be mapped to a host port using the \fB-p\fR flag. For example a httpd port 80 can be mapped to the host port 8080 using the following:
|
||||||

.B Creating and Mounting a Data Volume Container
|
||||||
|
.TP
|
||||||
|
Many applications require the sharing of persistent data across several containers. Docker allows you to create a Data Volume Container that other containers can mount from. For example, create a named container that contains directories /var/volume1 and /tmp/volume2. The image will need to contain these directories so a couple of RUN mkdir instructions might be required for you fedora-data image:
|
||||||
|
.sp
|
||||||
|
.RS
|
||||||
|
docker run --name=data -v /var/volume1 -v /tmp/volume2 -i -t fedora-data true
|
||||||
|
.sp
|
||||||
|
docker run --volumes-from=data --name=fedora-container1 -i -t fedora bash
|
||||||
|
.RE
|
||||||
|
.sp
|
||||||
|
.TP
|
||||||
|
Multiple -volumes-from parameters will bring together multiple data volumes from multiple containers. And it's possible to mount the volumes that came from the DATA container in yet another container via the fedora-container1 intermidiery container, allowing to abstract the actual data source from users of that data:
|
||||||
|
.sp
|
||||||
|
.RS
|
||||||
|
docker run --volumes-from=fedora-container1 --name=fedora-container2 -i -t fedora bash
|
||||||
|
.RE
|
||||||
|
.TP
|
||||||
|
.sp
|
||||||
|
.B Mounting External Volumes
|
||||||
|
.TP
|
||||||
|
To mount a host directory as a container volume, specify the absolute path to the directory and the absolute path for the container directory separated by a colon:
|
||||||
|
.sp
|
||||||
|
.RS
|
||||||
|
docker run -v /var/db:/data1 -i -t fedora bash
|
||||||
|
.RE
|
||||||
|
.sp
|
||||||
|
.TP
|
||||||
|
When using SELinux, be aware that the host has no knowledge of container SELinux policy. Therefore, in the above example, if SELinux policy is enforced, the /var/db directory is not writable to the container. A "Permission Denied" message will occur and an avc: message in the host's syslog.
|
||||||
|
.sp
|
||||||
|
.TP
|
||||||
|
To work around this, at time of writing this man page, the following command needs to be run in order for the proper SELinux policy type label to be attached to the host directory:
|
||||||
|
.sp
|
||||||
|
.RS
|
||||||
|
chcon -Rt svirt_sandbox_file_t /var/db
|
||||||
|
.RE
|
||||||
|
.sp
|
||||||
|
.TP
|
||||||
|
Now, writing to the /data1 volume in the container will be allowed and the changes will also be reflected on the host in /var/db.

.SH DESCRIPTION
|
||||||
|
\fBdocker\fR has two distinct functions. It is used for starting the Docker daemon and to run the CLI (i.e., to command the daemon to manage images, containers etc.) So \fBdocker\fR is both a server as deamon and a client to the daemon through the CLI.
|

|
||||||
|
The Docker CLI has over 30 commands. The commands are listed below and each has its own man page which explain usage and arguements.
