# buildah-copy "1" "April 2021" "buildah"
|
|
|
|
## NAME
|
|
buildah\-copy - Copies the contents of a file, URL, or directory into a container's working directory.
|
|
|
|
## SYNOPSIS
|
|
**buildah copy** *container* *src* [[*src* ...] *dest*]
|
|
|
|
## DESCRIPTION
|
|
Copies 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 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 content.
|
|
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`
|
|
|
|
**--chmod** *permissions*
|
|
|
|
Sets the access permissions of the destination content. Accepts the numerical 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 a the context directory. This means copying files pointed at
|
|
by symbolic links outside of the chroot will fail.
|
|
|
|
**--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.
|
|
|
|
**--quiet**, **-q**
|
|
|
|
Refrain from printing a digest of the copied content.
|
|
|
|
## EXAMPLE
|
|
|
|
buildah copy containerID '/myapp/app.conf' '/myapp/app.conf'
|
|
|
|
buildah copy --chown myuser:mygroup containerID '/myapp/app.conf' '/myapp/app.conf'
|
|
|
|
buildah copy --chmod 660 containerID '/myapp/app.conf' '/myapp/app.conf'
|
|
|
|
buildah copy containerID '/home/myuser/myproject.go'
|
|
|
|
buildah copy containerID '/home/myuser/myfiles.tar' '/tmp'
|
|
|
|
buildah copy containerID '/tmp/workingdir' '/tmp/workingdir'
|
|
|
|
buildah copy containerID 'https://github.com/containers/buildah' '/tmp'
|
|
|
|
buildah copy containerID 'passwd' 'certs.d' /etc
|
|
|
|
## FILES
|
|
|
|
### .containerignore/.dockerignore
|
|
|
|
If the .containerignore/.dockerignore file exists in the context directory,
|
|
`buildah copy` reads its contents. If both exist, then .containerignore is used.
|
|
|
|
When the \fB\fC\-\-ignorefile\fR option is specified Buildah reads it and
|
|
uses it to decide which content to exclude when copying content into the
|
|
working container.
|
|
|
|
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 ends 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 directory.
|
|
|
|
`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/.dockerignore file that uses this
|
|
mechanism:
|
|
```
|
|
*.doc
|
|
!Help.doc
|
|
```
|
|
|
|
Exclude all doc files except Help.doc when copying content into the container.
|
|
|
|
This functionality is compatible with the handling of .dockerignore files described here:
