A tool for interacting with Procfiles.
Install it using the "go get" command:
go get github.com/josegonzalez/go-procfile-util
All commands take a -P or --procfile flag to specify an alternative Procfile path. If not specified, procfile-util will attempt to read the Procfile from the current directory.
check that the specified procfile is valid
procfile-util check
delete a process type from a procfile
This command does not retain comments or extra newline characters. Specifying both the write-path and stdout flags will result in an error.
# delete the web process and write the file
procfile-util delete --process web
# delete the web process and write output to other.Procfile
procfile-util delete --process web --write-path other.Procfile
# delete the web process and write output to stdout
procfile-util delete --process web --stdout
check if a process type exists
# returns 0 if the web process type exists
procfile-util exists -p web
# returns 1 if the non-existent process type does not exist
procfile-util exists -p non-existent
expands a procfile against a specific environment
# expand variables with no implicit env vars
# will result in empty string for variable replacements
procfile-util expand
# specify a default-port to use (default: 5000)
procfile-util expand --default-port 3000
# expand variables with getenv used for variable expansion
# may use any variable available when executing procfile-util
procfile-util expand --allow-getenv
# expand variables with a parsed .env file used for variable expansion
procfile-util expand --env-file .env
# combines getenv and .env file parsing to provide variable expansion
procfile-util expand --allow-getenv --env-file .env
# specify the default-port when performing variable expansion
procfile-util expand --allow-getenv --env-file .env --default-port 3000
export the application to another process management format
Due to argument parsing limitations, the --location flag is currently required.
In addition, not all formats support all arguments, and not all arguments have examples below.
# export systemd init files to the `tmp` directory
# support formats include: [launchd, runit, systemd, systemd-user, sysv, upstart]
# the default format is: systemd
procfile-util export --format systemd --location tmpp
# override the app name
procfile-util export --location tmp --app node-js-app
# set the group and user used to launch processes
procfile-util export --location tmp --group root --user root
# set a working directory path for the process
procfile-util export --location tmp --working-directory /root
list all process types in a procfile
procfile-util list
set the command for a process type in a procfile
This command does not retain comments or extra newline characters. Specifying both the write-path and stdout flags will result in an error.
# set the web process and write the file
procfile-util set --process web --command "python app.py -p $PORT"
# set the web process and write output to other.Procfile
procfile-util set --process web --command "python app.py -p $PORT" --write-path other.Procfile
# set the web process and write output to stdout
procfile-util set --process web --command "python app.py -p $PORT" --stdout
show the command for a specific process type
# shows the command for the web process
procfile-util show -p web
# shows the command for the web process
# specify a default-port to use (default: 5000)
procfile-util show -p web --default-port 3000
# shows the command for the web process
# expand variables with getenv used for variable expansion
# may use any variable available when executing procfile-util
procfile-util show -p web --allow-getenv
# shows the command for the web process
# expand variables with a parsed .env file used for variable expansion
procfile-util show -p web --env-file .env
# shows the command for the web process
# combines getenv and .env file parsing to provide variable expansion
procfile-util show -p web --allow-getenv --env-file .env
# shows the command for the web process
# specify the default-port when performing variable expansion
procfile-util show web --allow-getenv --env-file .env --default-port 3000
