configure

Handles an environment file and variable of a service depending on the options passed.

Interface

configure [ -h ] [ -c version ] [ -s version ] [ -V|L ] [ -r key=value ] [ -i src,dst ] [ -e editor ] service

This command allows to handle the configuration file of service found by default at /etc/66/conf/<service>. Depending of the options passed, you can displays the contents of the file, see the current version used, edits the configuration file and so on.

The edition of the configuration file is the default option if neither option is passed.

Options

• -h: prints this help.

• -c version: makes version as the current one to use by default. If the service is already running, you need to restart the service to apply the change by the command e.g. 66 restart foo.

• -s version: specifies the version to handles with the options -V, -L, -r and -e instead of using the current one.

• -V: lists available versioned configuration directories of the service. The term current is used to specific the current version in use as follow:

  0.2.0
  0.1.4 current

  - -r key=value: override an existing key=value pair with the given one. The key=value needs to be single quoted in case of multiple arguments.This option can be specified multiple times.

• -L: lists defined environment variables for the service. It do the same for all files found at the configuration directory.

• -i src,dst: imports configuration file from src version to dst version. For instance, 0.3.1 is the src and 0.7.0 is the dest. The src version and dst version need to be separated by a comma without space before and after it. It do not import the configuration written by the parse process but only deal with extra configuration files written by the sysadmin.

• -e editor: edit the configuration file with editor. If you don't specify this option, it try to found the EDITOR variable from the environment variable. Note: the upstream file (meaning the one prefixed with a dot) is never touched. A copy of the upstream file is copied (if it doesn't exist yet) and the configure command modifies that file.(see Service configuration file for further information).

Usage examples

Lists the defined environment variable of the service foo

66 configure -L foo

Change the value of the CMD_ARGS variable for the service nginx

66 configure -r CMD_ARGS='-c /etc/nginx/nginx.conf -g "daemon off;"' nginx

Import the configuration file from the 0.1.6 version to th e0.1.7 version of the service foo

66 configure -i 0.1.6,0.1.7 foo

Get the list of version available for the service foo

66 configure -V foo

Edit the configuration file of the service foo using the nano editor

sudo 66 configure -e nano foo

See the the defined environment variable of the service foo from the 0.1.6 version

66 configure -s 0.1.6 -L foo

List the defined environment variables of the service barz of the module foo@foobar

66 configure -L foo@foobar:barz

Notes

Removing a key from the environment variable during the execution time of the service can be handled by using an exclamation mark ! at the begin of the value:

66 configure -r 'CMD_ARGS=!-c /etc/nginx/nginx.conf -g "daemon off;"' nginx

It this case the CMD_ARGS variable is not define at the environment variable of the service.
