# For more information on this configuration file, see containers-registries.conf(5).
|
|
#
|
|
# There are multiple versions of the configuration syntax available, where the
|
|
# second iteration is backwards compatible to the first one. Mixing up both
|
|
# formats will result in an runtime error.
|
|
#
|
|
# The initial configuration format looks like this:
|
|
#
|
|
# Registries to search for images that are not fully-qualified.
|
|
# i.e. foobar.com/my_image:latest vs my_image:latest
|
|
#
|
|
# NOTE: RISK OF USING UNQUALIFIED IMAGE NAMES.
|
|
# Pulling an image that is not fully qualified, i.e., one that includes the
|
|
# image name but does not include the registry or tag, is not recommended.
|
|
# There is a risk that the image being pulled could be spoofed. An example
|
|
# of this would be if a user wanted to pull an image named `foobar` from a
|
|
# registry and expect it to come from myregistry.com. If myregistry.com is
|
|
# not first in the search list, an attacker could place a different `foobar`
|
|
# image at a registry earlier in the search list. Now you would accidentally
|
|
# run the attackers code rather than the intended content. Registries that
|
|
# are added to this list should be completely controlled, i.e., not allow
|
|
# unknown/arbitrary users being able to create accounts with arbitrary names
|
|
# to prevent an image from being spoofed, squatted or otherwise made
|
|
# insecure. If it is necessary to use one of these registries, it should be
|
|
# added at the end of the list.
|
|
#
|
|
# It is recommended to use fully-qualified images for pulling as the
|
|
# destination registry is unambiguous. Pulling by digest
|
|
# (i.e., quay.io/repository/name@digest) further eliminates the ambiguity of
|
|
# tags.

|
# registries you want to allow users to pull and push from. policy.json gives greater flexibility, and
