Amrith Kumar 43e32116bd fix readme.rst to reflect correct environment variable
The readme.rst incorrectly refers to the environment variable
DIB_APT_KEYS which should be DIB_ADD_APT_KEYS. See [1] for usage in
code.

This is a minor correction to the readme only, no runnable code is
modified.

README.rst

dpkg

Provide dpkg specific image building glue.

The ubuntu element needs customisations at the start and end of the image build process that do not apply to RPM distributions, such as using the host machine HTTP proxy when installing packages. These customisations live here, where they can be used by any dpkg based element.

The dpkg specific version of install-packages is also kept here.

Environment Variables

DIB_ADD_APT_KEYS
Required

No

Default

None

Description

If an extra or updated apt key is needed then define DIB_ADD_APT_KEYS with the path to a folder. Any key files inside will be added to the key ring before any apt-get commands take place.

Example

DIB_ADD_APT_KEYS=/etc/apt/trusted.gpg.d

DIB_APT_LOCAL_CACHE
Required

No

Default

1

Description

By default the $DIB_IMAGE_CACHE/apt/$DISTRO_NAME directory is mounted in /var/cache/apt/archives to cache the .deb files downloaded during the image creation. Use this variable if you wish to disable the internal cache of the /var/cache/apt/archives directory

Example

DIB_APT_LOCAL_CACHE=0 will disable internal caching.

DIB_DISABLE_APT_CLEANUP
Required

No

Default

0

Description

At the end of a dib run we clean the apt cache to keep the image size as small as possible. Use this variable to prevent cleaning the apt cache at the end of a dib run.

Example

DIB_DISABLE_APT_CLEANUP=1 will disable cleanup.
