For example, the build option defines configuration options such as the Dockerfile path, the command option allows one to override default Docker commands, and more. [33] The first public beta version of Docker Compose (version 0.0.1) was released on December 21, 2013. [34] The first production-ready version (1.0) was made available on October ...
The command definition language supports many types of options, for example dates and file specifications, and allows a qualifier to change the image invoked—for example "CREATE", to create a file, vs. "CREATE/DIRECTORY" to create a directory. The other (simpler, but less flexible) method to define commands is via foreign commands. This is ...
Other examples include: convert a source image file to another format, copy a file to a content management system, and send e-mail about build status. A makefile defines targets where each is either a file to generate or is a user-defined concept, called a phony target.
Most modern implementations of a function call use a call stack, a special case of the stack data structure, to implement function calls and returns. Each procedure call creates a new entry, called a stack frame , at the top of the stack; when the procedure returns, its stack frame is deleted from the stack, and its space may be used for other ...
It includes all commands that are standardized by the Internet Engineering Task Force (IETF) in RFC 959, plus extensions. Note that most command-line FTP clients present their own non-standard set of commands to users. For example, GET is the common user command to download a file instead of the raw command RETR.
The length of a string is the number of code units before the zero code unit. [1] The memory occupied by a string is always one more code unit than the length, as space is needed to store the zero terminator. Generally, the term string means a string where the code unit is of type char, which is exactly 8 bits on all modern machines.
