# DESCRIPTION
A credentials file in JSON format used to authenticate against container image registries.
A file in JSON format controlling authentication against container image registries.
The primary (read/write) file is stored at `${XDG_RUNTIME_DIR}/containers/auth.json` on Linux;
on Windows and macOS, at `$HOME/.config/containers/auth.json`.
When searching for the credential for a registry, the following files will be read in sequence until the valid credential is found:
first reading the primary (read/write) file, or the explicit override using an option of the calling application.
If credentials are not present, search in `${XDG_CONFIG_HOME}/containers/auth.json` (usually `~/.config/containers/auth.json`), `$HOME/.docker/config.json`, `$HOME/.dockercfg`.
If credentials are not present there,
the search continues in `${XDG_CONFIG_HOME}/containers/auth.json` (usually `~/.config/containers/auth.json`), `$HOME/.docker/config.json`, `$HOME/.dockercfg`.
Except the primary (read/write) file, other files are read-only, unless the user use an option of the calling application explicitly points at it as an override.
Except for the primary (read/write) file, other files are read-only unless the user, using an option of the calling application, explicitly points at it as an override.
## FORMAT
The auth.json file stores encrypted authentication information for the
user to container image registries. The file can have zero to many entries and
is created by a `login` command from a container tool such as `podman login`,
`buildah login` or `skopeo login`. Each entry either contains a single
hostname (e.g. `docker.io`) or a namespace (e.g. `quay.io/user/image`) as a key
and an auth token in the form of a base64 encoded string as value of `auth`. The
token is built from the concatenation of the username, a colon, and the
password. The registry name can additionally contain a repository name (an image
name without tag or digest) and namespaces. The path (or namespace) is matched
in its hierarchical order when checking for available authentications. For
example, an image pull for `my-registry.local/namespace/user/image:latest` will
The auth.json file stores, or references, credentials that allow the user to authenticate
to container image registries.
It is primarily managed by a `login` command from a container tool such as `podman login`,
`buildah login`, or `skopeo login`.
Each entry contains a single hostname (e.g., `docker.io`) or a namespace (e.g., `quay.io/user/image`) as a key,
and credentials in the form of a base64-encoded string as value of `auth`. The
base64-encoded string contains a concatenation of the username, a colon, and the
password.
When checking for available credentials, the relevant repository is matched
against available keys in its hierarchical order, going from most-specific to least-specific.
For example, an image pull for `my-registry.local/namespace/user/image:latest` will
result in a lookup in `auth.json` in the following order:

An entry can be removed by using a `logout` command from a container

In addition, credential helpers can be configured for specific registries and the credentials-helper
software can be used to manage the credentials in a more secure way than depending on the base64 encoded authentication
provided by `login`. If the credential helpers are configured for specific registries, the base64 encoded authentication will not be used
for operations concerning credentials of the specified registries.
In addition, credential helpers can be configured for specific registries, and the credentials-helper
software can be used to manage the credentials more securely than storing only base64-encoded credentials in `auth.json`.
When the credential helper is in use on a Linux platform, the auth.json file would contain keys that specify the registry domain, and values that specify the suffix of the program to use (i.e. everything after docker-credential-). For example:

## Supported transports and their scopes
See containers-transports(5) for general documentation about the transports and their reference syntax.
### `atomic:`
The `atomic:` transport refers to images in an Atomic Registry.
The deprecated `atomic:` transport refers to images in an Atomic Registry.
Supported scopes use the form _hostname_[`:`_port_][`/`_namespace_[`/`_imagestream_ [`:`_tag_]]],
i.e. either specifying a complete name of a tagged image, or prefix denoting
a host/namespace/image stream or a wildcarded expression for matching all
a host/namespace/image stream, or a wildcarded expression starting with `*.` for matching all
subdomains. For wildcarded subdomain matching, `*.example.com` is a valid case, but `example*.*.com` is not.
*Note:* The _hostname_ and _port_ refer to the container registry host and port (the one used
e.g. for `docker pull`), _not_ to the OpenShift API host and port.
### `containers-storage:`
Supported scopes have the form `[`_storage-specifier_`]`_image-scope_.
`[`_storage-specifier_`]` is usually `[`_graph-driver-name_`@`_graph-root_`]`, e.g. `[overlay@/var/lib/containers/storage]`.
_image-scope_ matching the individual image is
- a named Docker reference *in the fully expanded form*, either using a tag or digest. For example, `docker.io/library/busybox:latest` (*not* `busybox:latest`)
- and/or (depending on which one the users input provides) `@`_image-id_
More general scopes are prefixes of individual-image scopes, and specify a less-precisely-specified image, or a repository
(by omitting first the image ID, if any; then the digest, if any; and finally a tag, if any),
a repository namespace, or a registry host (by only specifying the host name and possibly a port number).
Finally, two full-store specifiers matching all images in the store are valid scopes:
- `[`_graph-driver-name_`@`_graph-root_`]` and
- `[`_graph-root_`]`
Note that some tools like Podman and Buildah hard-code overrides of the signature verification policy for “push” operations,
allowing these operations regardless of configuration in `policy.json`.

Supported scopes use the form _directory_`:`_tag_, and _directory_ referring to
a directory containing one or more tags, or any of the parent directories.
Supported scopes are paths to directories

Supported scopes are paths to OCI archives, and their parent directories
(either containing a single archive, or subdirectories possibly containing archives).
The _reference_ annotation value, if any, is not used.
*Note:*
- The paths must be absolute and contain no symlinks. Paths violating these requirements may be silently ignored.
- The top-level scope `"/"` is forbidden; use the transport default scope `""`,
for consistency with other transports.
### `ostree`:
Supported scopes have the form _repo-path_`:`_image-scope_; _repo_path_ is the path to the OSTree repository.
_image-scope_ is the _docker_reference_ part of the reference, with with a `:latest` tag implied if no tag is present,
and parent namespaces of the _docker_reference_ value (by omitting the tag, or a prefix specifying a higher-level namespace).
*Note:*
- The _repo_path_ must be absolute and contain no symlinks. Paths violating these requirements may be silently ignored.
### `sif:`

(either containing images, or subdirectories possibly containing images).
*Note:*

- The top-level scope `"/"` is forbidden; use the transport default scope `""`,

The `signedIdentity` field has the same semantics as in the `signedBy` requirement described above.
Note that `cosign`-created signatures only contain a repository, so only `matchRepository` and `exactRepository` can be used to accept them (and that does not protect against substitution of a signed image with an unexpected tag).
To use this with images hosted on image registries, the relevant registry or repository must have the `use-sigstore-attachments` option enabled in containers-registries.d(5).

By default, images in the storage library are stored in the `graphroot`. If `imagestore` is provided, newly pulled images will be stored in the `imagestore` location. All other storage continues to be stored in the `graphroot`. When using the `overlay` driver, images previously stored in the `graphroot` remain accessible. Internally, the storage library mounts `graphroot` as an `additionalImageStore` to allow this behavior.
A common use case for the `imagestore` field is users who need to split filesystems in different partitions. The `imagestore` partition stores images and the `graphroot` partition stores container content created from the images.
Imagestore, if set, must be different from `graphroot`.

Setting this option only has an effect if the local storage has not been initialized yet and the driver name is not set.

Transient store mode makes all container metadata be saved in temporary storage

**remap-uids=**""
**remap-gids=**""
Remap-UIDs/GIDs is the mapping from UIDs/GIDs as they should appear inside of a container, to the UIDs/GIDs outside of the container, and the length of the range of UIDs/GIDs. Additional mapped sets can be listed and will be heeded by libraries, but there are limits to the number of mappings which the kernel will allow when you later attempt to run a container.
Example
remap-uids = 0:1668442479:65536
remap-gids = 0:1668442479:65536
remap-uids = "0:1668442479:65536"
remap-gids = "0:1668442479:65536"
These mappings tell the container engines to map UID 0 inside of the container to UID 1668442479 outside. UID 1 will be mapped to 1668442480. UID 2 will be mapped to 1668442481, etc, for the next 65533 UIDs in succession.
**remap-user**=""
**remap-group**=""
Remap-User/Group is a user name which can be used to look up one or more UID/GID ranges in the /etc/subuid or /etc/subgid file. Mappings are set up starting with an in-container ID of 0 and then a host-level ID taken from the lowest range that matches the specified name, and using the length of that range. Additional ranges are then assigned, using the ranges which specify the lowest host-level IDs first, to the lowest not-yet-mapped in-container ID, until all of the entries have been used for maps.

## ENVIRONMENT VARIABLES
If the `CONTAINERS_CONF` environment variable is set, all system and user
config files are ignored and only the specified config file will be loaded.
If the `CONTAINERS_CONF_OVERRIDE` path environment variable is set, the config
file will be loaded last even when `CONTAINERS_CONF` is set.
The values of both environment variables may be absolute or relative paths, for
instance, `CONTAINERS_CONF=/tmp/my_containers.conf`.
## MODULES
A module is a containers.conf file located directly in or a sub-directory of the following three directories:
- __$HOME/.config/containers/containers.conf.modules__
- __/etc/containers/containers.conf.modules__
- __/usr/share/containers/containers.conf.modules__
Files in those locations are not loaded by default but only on-demand. They are loaded after all system and user configuration files but before `CONTAINERS_CONF_OVERRIDE` hence allowing for overriding system and user configs.
Modules are currently supported by podman(1). The `podman --module` flag allows for loading a module and can be specified multiple times. If the specified value is an absolute path, the config file will be loaded directly. Relative paths are resolved relative to the three module directories mentioned above and in the specified order such that modules in `$HOME` allow for overriding those in `/etc` and `/usr/share`. Modules in `$HOME` (or `$XDG_CONFIG_HOME` if specified) are only used for rootless users.
## APPENDING TO STRING ARRAYS
The default behavior during the loading sequence of multiple containers.conf files is to override previous data. To change the behavior from overriding to appending, you can set the `append` attribute as follows: `array=["item-1", "item=2", ..., {append=true}]`. Setting the append attribute instructs to append to this specific string array for the current and also subsequent loading steps. To change back to overriding, set `{append=false}`.
Consider the following example:
```
modules1.conf: env=["1=true"]
modules2.conf: env=["2=true"]
modules3.conf: env=["3=true", {append=true}]
modules3.conf: env=["4=true"]
```
After loading the files in the given order, the final contents are `env=["2=true", "3=true", "4=true"]`. If modules4.conf would set `{append=false}`, the final contents would be `env=["4=true"]`.

**containers.conf**
Distributions often provide a `/usr/share/containers/containers.conf` file to
define default container configuration. Administrators can override fields in
this file by creating `/etc/containers/containers.conf` to specify their own
configuration. Rootless users can further override fields in the config by
creating a config file stored in the `$HOME/.config/containers/containers.conf` file.
Distributions often provide a __/usr/share/containers/containers.conf__ file to
provide a default configuration. Administrators can override fields in this
file by creating __/etc/containers/containers.conf__ to specify their own
configuration. They may also drop `.conf` files in
__/etc/containers/containers.conf.d__ which will be loaded in alphanumeric order.
Rootless users can further override fields in the config by creating a config
file stored in the __$HOME/.config/containers/containers.conf__ file or __.conf__ files in __$HOME/.config/containers/containers.conf.d__.
If the `CONTAINERS_CONF` path environment variable is set, just
this path will be used. This is primarily used for testing.
Fields specified in the containers.conf file override the default options, as
well as options in previously read containers.conf files.
Fields specified in a containers.conf file override the default options, as
well as options in previously loaded containers.conf files.
**storage.conf**
The `/etc/containers/storage.conf` file is the default storage configuration file.
Rootless users can override fields in the storage config by creating
`$HOME/.config/containers/storage.conf`.
__$HOME/.config/containers/storage.conf__.
If the `CONTAINERS_STORAGE_CONF` path environment variable is set, this path
is used for the storage.conf file rather than the default.
