NAME

       skopeo-copy - Copy an image (manifest, filesystem layers, signatures) from one location to
       another.

SYNOPSIS

       skopeo copy [options] source-image destination-image

DESCRIPTION

       Copy an image (manifest, filesystem layers, signatures) from one location to another.

       Uses the system's trust policy to validate images,  rejects  images  not  trusted  by  the
       policy.

       source-image use the "image name" format described above

       destination-image use the "image name" format described above

       source-image  and  destination-image  are  interpreted  completely independently; e.g. the
       destination name does not automatically inherit any parts of the source name.

OPTIONS

       --additional-tag=strings

       Additional tags (supports docker-archive).

       --all, -a

       If source-image refers to a list of images,  instead  of  copying  just  the  image  which
       matches  the  current OS and architecture (subject to the use of the global --override-os,
       --override-arch and --override-variant options), attempt to copy all of the images in  the
       list, and the list itself.

       --authfile path

       Path of the authentication file. Default is ${XDG_RUNTIME_DIR}/containers/auth.json, which
       is  set  using  skopeo  login.   If  the  authorization  state   is   not   found   there,
       $HOME/.docker/config.json is checked, which is set using docker login.

       Note:  You  can  also  override the default path of the authentication file by setting the
       REGISTRY_AUTH_FILE environment variable. export REGISTRY_AUTH_FILE=path

       --src-authfile path

       Path of the authentication file for the source registry. Uses path given by --authfile, if
       not provided.

       --dest-authfile path

       Path  of  the  authentication  file  for  the  destination  registry.  Uses  path given by
       --authfile, if not provided.

       --dest-shared-blob-dir directory

       Directory to use to share blobs across OCI repositories.

       --digestfile path

       After copying the image, write the digest of the resulting image to the file.

       --preserve-digests

       Preserve the digests during copying. Fail if the digest cannot be preserved.

       --encrypt-layer ints

       Experimental the 0-indexed layer indices, with support for negative indexing  (e.g.  0  is
       the first layer, -1 is the last layer)

       --format, -f manifest-type

       MANIFEST  TYPE (oci, v2s1, or v2s2) to use in the destination (default is manifest type of
       source, with fallbacks)

       --help, -h

       Print usage statement

       --multi-arch option

       Control what is copied if source-image refers to a multi-architecture  image.  Default  is
       system.

       Options:  -  system:  Copy only the image that matches the system architecture - all: Copy
       the full multi-architecture image - index-only: Copy only the index

       The index-only option usually fails unless  the  referenced  per-architecture  images  are
       already present in the destination, or the target registry supports sparse indexes.

       --quiet, -q

       Suppress output information when copying images.

       --remove-signatures

       Do  not  copy signatures, if any, from source-image. Necessary when copying a signed image
       to a destination which does not support signatures.

       --sign-by key-id

       Add a “simple signing” signature using that key ID for  an  image  name  corresponding  to
       destination-image

       --sign-by-sigstore-private-key path

       Add  a  sigstore  signature using a private key at path for an image name corresponding to
       destination-image

       --sign-passphrase-file path

       The passphare to use when signing with --sign-by or  --sign-by-sigstore-private-key.  Only
       the  first line will be read. A passphrase stored in a file is of questionable security if
       other users can read this file. Do not use this option if at all avoidable.

       --sign-identity reference

       The identity to use when signing the image. The identity must be a fully specified  docker
       reference. If the identity is not specified, the target docker reference will be used.

       --src-shared-blob-dir directory

       Directory to use to share blobs across OCI repositories.

       --encryption-key protocol:keyfile

       Specifies  the  encryption  protocol, which can be JWE (RFC7516), PGP (RFC4880), and PKCS7
       (RFC2315)  and  the  key  material  required   for   image   encryption.   For   instance,
       jwe:/path/to/key.pem or pgp:admin@example.com or pkcs7:/path/to/x509-file.

       --decryption-key key[:passphrase]

       Key  to  be  used  for  decryption  of  images. Key can point to keys and/or certificates.
       Decryption will be tried with all keys. If the key is protected by  a  passphrase,  it  is
       required to be passed in the argument and omitted otherwise.

       --src-creds username[:password]

       Credentials for accessing the source registry.

       --dest-compress

       Compress tarball image layers when saving to directory using the 'dir' transport. (default
       is same compression type as source).

       --dest-decompress

       Decompress tarball image layers when  saving  to  directory  using  the  'dir'  transport.
       (default is same compression type as source).

       --dest-oci-accept-uncompressed-layers

       Allow  uncompressed  image  layers  when saving to an OCI image using the 'oci' transport.
       (default is to compress things that aren't compressed).

       --dest-creds username[:password]

       Credentials for accessing the destination registry.

       --src-cert-dir path

       Use certificates at path (*.crt, *.cert, *.key) to  connect  to  the  source  registry  or
       daemon.

       --src-no-creds

       Access the registry anonymously.

       --src-tls-verify=bool

       Require HTTPS and verify certificates when talking to container source registry or daemon.
       Default to source registry setting.

       --dest-cert-dir path

       Use certificates at path (*.crt, *.cert, *.key) to connect to the destination registry  or
       daemon.

       --dest-no-creds

       Access the registry anonymously.

       --dest-tls-verify=bool

       Require  HTTPS  and  verify certificates when talking to container destination registry or
       daemon. Default to destination registry setting.

       --src-daemon-host host

       Copy from docker daemon at host. If host starts with tcp://, HTTPS is enabled by  default.
       To use plain HTTP, use the form http:// (default is unix:///var/run/docker.sock).

       --dest-daemon-host host

       Copy to docker daemon at host. If host starts with tcp://, HTTPS is enabled by default. To
       use plain HTTP, use the form http:// (default is unix:///var/run/docker.sock).

       Existing signatures, if any, are preserved as well.

       --dest-compress-format format

       Specifies the compression format to use.  Supported values are: gzip and zstd.

       --dest-compress-level format

       Specifies the compression level  to  use.   The  value  is  specific  to  the  compression
       algorithm used, e.g. for zstd the accepted values are in the range 1-20 (inclusive), while
       for gzip it is 1-9 (inclusive).

       --src-registry-token token

       Bearer token for accessing the source registry.

       --dest-registry-token token

       Bearer token for accessing the destination registry.

       --dest-precompute-digests

       Precompute digests to ensure layers are not uploaded that already exist on the destination
       registry.  Layers  with  initially  unknown digests (ex. compressing "on the fly") will be
       temporarily streamed to disk.

       --retry-times

       The number of times to retry. Retry wait time will be exponentially increased based on the
       number of failed attempts.

       --src-username

       The username to access the source registry.

       --src-password

       The password to access the source registry.

       --dest-username

       The username to access the destination registry.

       --dest-password

       The password to access the destination registry.

EXAMPLES

       To just copy an image from one registry to another:

              $ skopeo copy docker://quay.io/skopeo/stable:latest docker://registry.example.com/skopeo:latest

       To copy the layers of the docker.io busybox image to a local directory:

              $ mkdir -p /var/lib/images/busybox
              $ skopeo copy docker://busybox:latest dir:/var/lib/images/busybox
              $ ls /var/lib/images/busybox/*
                /tmp/busybox/2b8fd9751c4c0f5dd266fcae00707e67a2545ef34f9a29354585f93dac906749.tar
                /tmp/busybox/manifest.json
                /tmp/busybox/8ddc19f16526912237dd8af81971d5e4dd0587907234be2b83e249518d5b673f.tar

       To copy and sign an image:

              # skopeo copy --sign-by dev@example.com containers-storage:example/busybox:streaming docker://example/busybox:gold

       To encrypt an image:

              skopeo copy docker://docker.io/library/nginx:1.17.8 oci:local_nginx:1.17.8

              openssl genrsa -out private.key 1024
              openssl rsa -in private.key -pubout > public.key

              skopeo  copy --encryption-key jwe:./public.key oci:local_nginx:1.17.8 oci:try-encrypt:encrypted

       To decrypt an image:

              skopeo copy --decryption-key ./private.key oci:try-encrypt:encrypted oci:try-decrypt:decrypted

       To copy encrypted image without decryption:

              skopeo copy oci:try-encrypt:encrypted oci:try-encrypt-copy:encrypted

       To decrypt an image that requires more than one key:

              skopeo copy --decryption-key ./private1.key --decryption-key ./private2.key --decryption-key ./private3.key oci:try-encrypt:encrypted oci:try-decrypt:decrypted

       Container  images  can  also  be partially encrypted by specifying the index of the layer.
       Layers are 0-indexed indices, with support for negative indexing.  i.e.  0  is  the  first
       layer, -1 is the last layer.

       Let's  say out of 3 layers that the image docker.io/library/nginx:1.17.8 is made up of, we
       only want to encrypt the 2nd layer,

              skopeo  copy --encryption-key jwe:./public.key --encrypt-layer 1 oci:local_nginx:1.17.8 oci:try-encrypt:encrypted
