# tar Cookbook
[![Build Status](https://travis-ci.org/chef-cookbooks/tar.svg?branch=master)](https://travis-ci.org/chef-cookbooks/tar) [![Cookbook Version](https://img.shields.io/cookbook/v/tar.svg)](https://supermarket.chef.io/cookbooks/tar)
Installs tar and includes resources for managing remote tar files. `tar_package` handles remote source package compilation. `tar_extract` handles retrieving remote tar files and extracting them locally.
## Requirements
### Platforms
- Debian / Ubuntu derivatives
- RHEL and derivatives
- openSUSE / SUSE Linux Enterprises
- FreeBSD
### Chef
- Chef 12.7+
## Resources
### tar_package
The `tar_package` resource provides an easy way to download remote files and compile and install them. This only works for the most basic Autoconf programs that can do `./configure && make && make install`.
#### Actions
- `install` Installs the package
#### Properties
- `source`: name attribute. The source remote URL.
- `prefix`: Directory to be used as the `--prefix` configure flag.
- `source_directory`: Directory to which source files are downloaded.
- `creates`: prevent the command from running when the specified file already exists.
- `configure_flags`: Array of additional flags to be passed to `./configure`.
- `archive_name`: Specify a different name for the downloaded archive. Use it if the directory name inside the tar file is different than the name defined in the URL. Additionally, `tar_package` supports most `remote_file` [attributes](https://docs.chef.io/chef/resources.html#remote-file).
#### Example
```
tar_package 'http://pgfoundry.org/frs/download.php/1446/pgpool-3.4.1.tar.gz' do
prefix '/usr/local'
creates '/usr/local/bin/pgpool'
end
```
This will download, compile, and install the package from the given URL and install it into /usr/local.
### tar_extract
The `tar_extract` resource provides an easy way to extract tar files from downloaded or local files.
#### Actions
- `extract` Extracts the tar file from a url
- `extract_local` Extracts the tar file from a local file path
#### Properties
- `source`: name attribute. The source remote URL.
- `target_dir`: Directory to extract into, e.g. tar xzf -C (target_dir)
- `download_dir`: Directory to which tarball is downloaded (defaults to chef cache which requires root `group` and `user`).
- `creates`: prevent the command from running when the specified file already exists.
- `compress_char`: Flag for compression type, such as `z` for `gzip`. `man tar` for options.
- `tar_flags`: Array of additional flags to be passed to tar xzf command.
- `group`: Group name or group ID to extract the archive under. If set to non-root group, point to a `download_dir` the group has permission to access.
- `user`: User name or user ID to extract the archive under. If set to non-root user, point to a `download_dir` the user has permission to access. Additionally, `tar_extract` supports most `remote_file` [attributes](https://docs.chef.io/chef/resources.html#remote-file).
#### Example
```
tar_extract 'http://dev.mycoderepo.com/artifacts/mycode-1.2.3.tar.gz' do
target_dir '/opt/myapp/mycode'
creates '/opt/myapp/mycode/lib'
tar_flags [ '-P', '--strip-components 1' ]
end
```
This will download the tarball to cache, extract the contents to /opt/myapp/mycode, use the file '/opt/myapp/mycode/lib' to determine idempotency, and pass both '-P' and '--strip-components 1' flags to the tar xzf command.
```
tar_extract '/tmp/mycode-1.2.3.tar.gz' do
action :extract_local
target_dir '/opt/myapp/mycode'
creates '/opt/myapp/mycode/lib'
end
```
This will extract the contents of /tmp/mycode-1.2.3.tar.gz to /opt/myapp/mycode and use the file '/opt/myapp/mycode/lib' to determine idempotency.
