Owner frodo -mode 0600 # Take file content from stdin _file /home/frodo/.bashrc -source "/etc/skel/. Thus avoiding the need to install additional software there ("zero dependencies").Ĭdist reads its configuration from the initial manifest ( conf/manifest/init), in which hosts are mapped to Furthermore, shell is also commonly available on potential target systems, Shell scripts were chosen, because Unix System Administrators are usually proficient in readingĪnd writing shell scripts. Shell scripting is favored because of how simple it is to access environment variables, read files, and execute system commands.Īll user configurable parts are contained in manifests or gencode-scripts, which are shell scripts. zip file which always creates temporary folder and uncompress all files to this folder and run code. exe on Windows) but it is self-extracting. tools like pyinstaller put all code in one executable file (ie. Yeah, it would be a big challenge to put it all in one file, that's what a bundler does. Shell is the de facto language for writing cdist configuration scripts, but most of the scripts can be written in any language if they contain a suitable shebang line. In this case, it must be run on a custom server. There is also a less frequently used gencode-local script which outputs code to be run locally. gencode-remote runs on the local machine, but its standard output is sent to the remote machine and executed as a shell script. Gencode Scripts: The gencode-remote script is the main way to actually update the configuration of target nodes.Manifest: A type manifest can instantiate other types, making code re-use easy.It sometimes uses this information to skip creation of the file. The _file type uses explorers to determine whether the file being created already exists. Explorers: In addition to the global explorers described above, types sometimes have their own explorers that collect type-specific information from the remote machine.The _file type takes a group parameter which specifies to which Unix group should own the file. Parameters: Many types cannot be fully described by the object ID, and take additional information in the form of parameters.For example, the _file type's ID is the absolute path to the file. This ID is not random like a UUID, but rather is some unique identifier that is meaningful in relation to the type. The same type cannot be instantiated twice with the same ID. The link below will always have the most current version.Object ID: When a type is turned into an object, it is passed a unique object ID.Ansible's "roles" are the equivalent of cdist's types. Additionally, with more and more expanders in a single Bundle, I realized a Table of Contents would be very convenient. Instead, if there is a change detected, only that Bundle is re-rendered in Markdown. md ', ' w+ ') as mdout:Īfter using this script every couple new expanders I've made, I realized it was incredibly unnecessary to recreate every single file. " description " : " Creates default function statement. tcbundle files which look something like this: " expanders " : [ Yeah, it would be a big challenge to put it all in one file, thats what a bundler does. In the slack channel for TeaCode, there is a channel #expanders where people can share there expanders. In this case, it must be run on a custom server.
