buildah-add(1) General Commands Manual buildah-add(1) NAME buildah-add - Add the contents of a file, URL, or a directory to a con- tainer. SYNOPSIS buildah add [options] container src [[src ...] dest] DESCRIPTION Adds the contents of a file, URL, or a directory to a container's working directory or a specified location in the container. If a local source file appears to be an archive, its contents are extracted and added instead of the archive file itself. If a local directory is specified as a source, its contents are copied to the destination. OPTIONS --add-history Add an entry to the history which will note the digest of the added con- tent. Defaults to false. Note: You can also override the default value of --add-history by setting the BUILDAH_HISTORY environment variable. export BUILDAH_HISTORY=true --cert-dir path Use certificates at path (*.crt, *.cert, *.key) when connecting to reg- istries for pulling images named with the --from flag, and when connecting to HTTPS servers when fetching sources from locations specified with HTTPS URLs. The default certificates directory is /etc/containers/certs.d. --checksum checksum Checksum the source content. The value of checksum must be a standard con- tainer digest string. Only supported for HTTP sources. --chmod permissions Sets the access permissions of the destination content. Accepts the numeri- cal format. --chown owner:group Sets the user and group ownership of the destination content. --contextdir directory Build context directory. Specifying a context directory causes Buildah to chroot into that context directory. This means copying files pointed at by symbolic links outside of the chroot will fail. --exclude pattern Exclude copying files matching the specified pattern. Option can be speci- fied multiple times. See containerignore(5) for supported formats. --from containerOrImage Use the root directory of the specified working container or image as the root directory when resolving absolute source paths and the path of the context directory. If an image needs to be pulled, options recognized by buildah pull can be used. --ignorefile file Path to an alternative .containerignore (.dockerignore) file. Requires --contextdir be specified. --link Create an independent image layer for the added files instead of modifying the working container's filesystem. If buildah run creates a file and buil- dah add --link adds a file to the same path, the file from buildah add --link will be present in the committed image. The --link layer is applied after all container filesystem changes at commit time. --quiet, -q Refrain from printing a digest of the added content. --retry attempts Number of times to retry in case of failure when pulling images from reg- istries or retrieving content from HTTPS URLs. Defaults to 3. --retry-delay duration Duration of delay between retry attempts in case of failure when pulling images from registries or retrieving content from HTTPS URLs. Defaults to 2s. --timestamp seconds Set the timestamp ("mtime") for added content to exactly this number of seconds since the epoch (Unix time 0, i.e., 00:00:00 UTC on 1 January 1970) to help allow for deterministic builds. The destination directory into which the content is being copied will most likely reflect the time at which the content was added to it. --tls-verify bool-value Require verification of certificates when retrieving sources from HTTPS lo- cations, or when pulling images referred to with the --from* flag (defaults to true). TLS verification cannot be used when talking to an insecure reg- istry. EXAMPLE buildah add containerID '/myapp/app.conf' '/myapp/app.conf' buildah add --chown myuser:mygroup containerID '/myapp/app.conf' '/myapp/app.conf' buildah add --chmod 660 containerID '/myapp/app.conf' '/myapp/app.conf' buildah add containerID '/home/myuser/myproject.go' buildah add containerID '/home/myuser/myfiles.tar' '/tmp' buildah add containerID '/tmp/workingdir' '/tmp/workingdir' buildah add containerID 'https://github.com/containers/buil- dah/blob/main/README.md' '/tmp' buildah add containerID 'passwd' 'certs.d' /etc FILES .containerignore or .dockerignore If a .containerignore or .dockerignore file exists in the context direc- tory, buildah add reads its contents. If both exist, then .containerignore is used. When the --ignorefile option is specified Buildah reads it and uses it to decide which content to exclude when copying content into the working con- tainer. Users can specify a series of Unix shell glob patterns in an ignore file to identify files/directories to exclude. Buildah supports a special wildcard string ** which matches any number of directories (including zero). For example, */.go will exclude all files that end with .go that are found in all directories. Example .containerignore/.dockerignore file: # here are files we want to exclude */*.c **/output* src */*.c Excludes files and directories whose names end with .c in any top level subdirectory. For example, the source file include/rootless.c. **/output* Excludes files and directories starting with output from any di- rectory. src Excludes files named src and the directory src as well as any content in it. Lines starting with ! (exclamation mark) can be used to make exceptions to exclusions. The following is an example .containerignore file that uses this mechanism: *.doc !Help.doc Exclude all doc files except Help.doc when copying content into the con- tainer. This functionality is compatible with the handling of .containerignore files described here: https://github.com/containers/common/blob/main/docs/containerignore.5.md SEE ALSO buildah(1), containerignore(5) buildah April 2021 buildah-add(1)
