cron ^#0

Supports: xenial trusty

Cronify delivers a single cron.d file and a payload for executing scheduled
tasks.

Cronify

To encode the cron.d file:

$ base64 -w 0 my-cron-file

Then use the contents as the value for the 'cron_data' option.
A quick way to set this would be

$ juju set cron/0 cron_data=$(base64 -w 0 my-cron-file)

Create a file named payload.tgz and add bundle it with the charm under
'${CHARM_DIR}/files'.

cron_data: (string) A base64 encoded string containing the contents of the cron.d file.
cron_file_name: (string) The name of the cron.d file.
extra_packages: (string) Space separated list of extra deb packages to install.
install_keys: (string) List of signing keys for install_sources package sources, per charmhelpers standard format (a yaml list of strings encoded as a string). The keys should be the full ASCII armoured GPG public keys. While GPG key ids are also supported and looked up on a keyserver, operators should be aware that this mechanism is insecure. null can be used if a standard package signing key is used that will already be installed on the machine, and for PPA sources where the package signing key is securely retrieved from Launchpad.
install_sources: (string) List of extra apt sources, per charm-helpers standard format (a yaml list of strings encoded as a string). Each source may be either a line that can be added directly to sources.list(5), or in the form ppa:<user>/<ppa-name> for adding Personal Package Archives, or a distribution component to enable.
package_status: (string) The status of service-affecting packages will be set to this value in the dpkg database. Valid values are "install" and "hold".; install
payload_target: (string) The target path for the $CHARM_DIR/files/payload.tgz contents
