fly:tldr:3cebf

This command is using the command-line interface (CLI) tool called "fly" to interact with Concourse, a continuous integration and delivery (CI/CD) platform.

Here is a breakdown of the command and its arguments:

• fly: This is the command-line utility provided by Concourse. It is used to interact with the Concourse server.
• -t ${target_name}: This specifies the target Concourse instance where the pipeline will be set. A target is a saved connection to a Concourse server, usually defined with a name and connection details.
• set-pipeline: This command is used to create or update a pipeline in Concourse.
• --config ${pipeline-yml}: This specifies the YAML file containing the configuration of the pipeline. The ${pipeline-yml} placeholder should be replaced with the actual file path or URL of the pipeline's YAML configuration file.
• --pipeline ${pipeline_name}: This specifies the name of the pipeline. The ${pipeline_name} placeholder should be replaced with the desired name for the pipeline.

In summary, this command is used to set or update a pipeline in Concourse by providing a YAML configuration file and specifying the target Concourse instance and pipeline name.
