You can run commands on one or hundreds of computers with a single Windows PowerShell command. RPC больше не поддерживается. RPC is no longer supported. Дополнительные сведения о настройке см. For more information on setting this up, see: Многие командлеты Windows PowerShell имеют параметр ComputerName, который позволяет собирать данные и изменять параметры одного или нескольких удаленных компьютеров. Many Windows PowerShell cmdlets have the ComputerName parameter that enables you to collect data and change settings on one or more remote computers.

Они используют различные способы связи, многие из которых работают во всех операционных системах Windows, которые Windows PowerShell поддерживает без необходимости какой-либо настройки. They use a variety of communication technologies and many work on all Windows operating systems that Windows PowerShell supports without any special configuration. В эти командлеты входят следующие: Обычно командлеты, которые поддерживают удаленное взаимодействие без специальной настройки, имеют параметр ComputerName, но не имеют параметра Session.

Typically, cmdlets that support remoting without special configuration have the ComputerName parameter and do not have the Session parameter. Чтобы найти эти командлеты в сеансе, введите: To find these cmdlets in your session, type: Служба удаленного взаимодействия Windows PowerShell, использующая протокол WS-Management, позволяет запустить любую команду Windows PowerShell на одном или нескольких удаленных компьютерах. С ее помощью можно устанавливать постоянные подключения, запускать интерактивные сеансы 1: It lets you establish persistent connections, start 1: Чтобы использовать службу удаленного взаимодействия Windows PowerShell, удаленный компьютер должен быть настроен для удаленного управления.

To use Windows PowerShell remoting, the remote computer must be configured for remote management. Дополнительные сведения, в том числе инструкции, см. For more information, including instructions, see About Remote Requirements.

После настройки службы удаленного взаимодействия Windows PowerShell вам станут доступны многие стратегии удаленного взаимодействия.

After you have configured Windows PowerShell remoting, many remoting strategies are available to you. В остальной части этого документа перечислены только некоторые из них.

You use the -f flag with docker build to point to a Dockerfile anywhere in your file system. To tag the image into multiple repositories after the build, add multiple -t parameters when you run the build command:.

Before the Docker daemon runs the instructions in the Dockerfile , it performs a preliminary validation of the Dockerfile and returns an error if the syntax is incorrect:. The Docker daemon runs the instructions in the Dockerfile one-by-one, committing the result of each instruction to a new image if necessary, before finally outputting the ID of your new image. The Docker daemon will automatically clean up the context you sent. Whenever possible, Docker will re-use the intermediate images cache , to accelerate the docker build process significantly.

This is indicated by the Using cache message in the console output. For more information, see the Build cache section in the Dockerfile best practices guide:. Build cache is only used from images that have a local parent chain. This means that these images were created by previous builds or the whole chain of images was loaded with docker load.

If you wish to use build cache of a specific image you can specify it with --cache-from option. Images specified with --cache-from do not need to have a parent chain and may be pulled from other registries. The instruction is not case-sensitive. Docker runs instructions in a Dockerfile in order. Docker treats lines that begin with as a comment, unless the line is a valid parser directive. A marker anywhere else in a line is treated as an argument.

This allows statements like:. Parser directives are optional, and affect the way in which subsequent lines in a Dockerfile are handled. Parser directives do not add layers to the build, and will not be shown as a build step. A single directive may only be used once. Once a comment, empty line or builder instruction has been processed, Docker no longer looks for parser directives.

Instead it treats anything formatted as a parser directive as a comment and does not attempt to validate if it might be a parser directive. Therefore, all parser directives must be at the very top of a Dockerfile.

Parser directives are not case-sensitive. However, convention is for them to be lowercase. Convention is also to include a blank line following any parser directives.

Line continuation characters are not supported in parser directives. The unknown directive is treated as a comment due to not being recognized. In addition, the known directive is treated as a comment due to appearing after a comment which is not a parser directive.

Non line-breaking whitespace is permitted in a parser directive. Hence, the following lines are all treated identically:. The escape directive sets the character used to escape characters in a Dockerfile.

The escape character is used both to escape characters in a line, and to escape a newline. This allows a Dockerfile instruction to span multiple lines. Note that regardless of whether the escape parser directive is included in a Dockerfile , escaping is not performed in a RUN command, except at the end of a line. Consider the following example which would fail in a non-obvious way on Windows.

The result of this dockerfile is that second and third lines are considered a single instruction:. By adding the escape parser directive, the following Dockerfile succeeds as expected with the use of natural platform semantics for file paths on Windows:.

Environment variables declared with the ENV statement can also be used in certain instructions as variables to be interpreted by the Dockerfile. Escapes are also handled for including variable-like syntax into a statement literally. In all cases, word can be any string, including additional environment variables.

Environment variables are supported by the following list of instructions in the Dockerfile:. Environment variable substitution will use the same value for each variable throughout the entire instruction. In other words, in this example:. However, ghi will have a value of bye because it is not part of the same instruction that set abc to bye. Before the docker CLI sends the context to the docker daemon, it looks for a file named.

If this file exists, the CLI modifies the context to exclude files and directories that match patterns in it. This helps to avoid unnecessarily sending large or sensitive files and directories to the daemon and potentially adding them to images using ADD or COPY. The CLI interprets the.

For the purposes of matching, the root of the context is considered to be both the working and the root directory. Neither excludes anything else. If a line in. A preprocessing step removes leading and trailing whitespace and eliminates.

Lines that are blank after preprocessing are ignored. The following is an example. Consider the following example:. The middle line has no effect because! You can even use the. These files are still sent to the daemon because it needs them to do its job. Finally, you may want to specify which files to include in the context, rather than which to exclude.

For historical reasons, the pattern. The image can be any valid image — it is especially easy to start by pulling an image from the Public Repositories. FROM can appear multiple times within a single Dockerfile to create multiple images or use one build stage as a dependency for another. Each FROM instruction clears any state created by previous instructions.

The tag or digest values are optional. If you omit either of them, the builder assumes a latest tag by default. The builder returns an error if it cannot find the tag value. The RUN instruction will execute any commands in a new layer on top of the current image and commit the results. The resulting committed image will be used for the next step in the Dockerfile.

The exec form makes it possible to avoid shell string munging, and to RUN commands using a base image that does not contain the specified shell executable. For example, consider these two lines:. Unlike the shell form, the exec form does not invoke a command shell. This means that normal shell processing does not happen. If you want shell processing then either use the shell form or execute a shell directly, for example: When using the exec form and executing a shell directly, as in the case for the shell form, it is the shell that is doing the environment variable expansion, not docker.

In the JSON form, it is necessary to escape backslashes. This is particularly relevant on Windows where the backslash is the path separator. Коэффициент запаса прочности обечайки.
