Artifactory is a fully-fledged RPM repository. As such, it enables:
- RPM metadata calculation for RPMs hosted in Artifactory local repositories.
- Deploying RPM Modules to Artifactory local repositories.
- Provisioning RPMs directly from Artifactory to YUM clients.
- Detailed RPM metadata views from Artifactory's web UI.
- Providing GPG signatures that can be used by the YUM client to authenticate RPMs.
Valid for YUM also
The instructions on this page can be used for RPM repositories and YUM repositories interchangeably.
RPM Metadata for Hosted RPMs
The RPM metadata generated by Artifactory is identical to the basic-mode output of the Red Hat-based Linux command
A folder named
repodata is created in the configured location within a local repository with the following files in it:
|Contains an XML file describing the primary metadata of each RPM archive.|
|Contains an XML file describing all the files contained within each RPM archive.|
|Contains an XML file describing miscellaneous information regarding each RPM archive.|
|Contains information regarding all the other metadata files.|
YUM Support is Platform Independent!
Artifactory's RPM metadata calculation is based on pure Java.
It does not rely on the existence of the
createrepo binary or on running external processes on the host on which Artifactory is running.
Triggering RPM Metadata Updates
When enabled, the metadata calculation is triggered automatically by some actions, and can also be invoked manually by others. Either way, the metadata produced is served to YUM clients.
RPM metadata is automatically calculated:
- When deploying/removing/copying/moving an RPM file.
- When performing content import (both system and repository imports).
You can manually invoke RPM metadata calculation:
- By selecting the local repository in the Tree Browser and clicking Recalculate Index in the Actions menu.
- Via Artifactory's REST-API.
Metadata calculation cleans up RPM metadata that already existed as a result of manual deployment or import. This includes RPM metadata stored as SQLite database files.
Indexing the File List
filelists.xml metadata file of an RPM repository contains a list of all the files in each package hosted in the repository. When the repository contains many packages, reindexing this file as a result of interactions with the YUM client can be resource intensive causing a degradation of performance. Therefore, from version 5.4, reindexing this file is initially disabled when an RPM repository is created. To enable indexing
filelists.xml, set the Enable File List Indexing checkbox.
Note that the
filelists.xml metadata file for a virtual repository may not be complete (i.e. it may not actually list all the files it aggregates) if any of the repositories it aggregates do not have file listing enabled. Note that if indexing of the
filelists.xml file is disabled, it is not possible to search for a file using the YUM client to determine which package wrote the queried file to the filesystem.
To create an RPM local repository, select RPM as the Package Type when you create the repository.
To enable automatic RPM metadata calculation on a local RPM repository, in the RPM Settings section of the Basic settings screen, set Auto-calculate RPM Metadata.
RPM Metadata Folder Depth
Informs Artifactory under which level of directory to search for RPMs and save the
By default this value is 0 and refers to the repository's root folder. In this case, Artifactory searches the entire repository for RPMs and saves the
Using a different depth is useful in cases where generating metadata for a repository separates its artifacts by name, version and architecture. This will allow you to create multiple RPM repositories under the same Artifactory RPM repository.
When changing the configured depth of existing repository, packages indexed in the old depth might need to be re-indexed or moved to a new depth to be available in the new configured depth, and YUM clients might need to change their configuration to point to the new depth.depth.
Auto-calculate RPM Metadata
|When set, RPM metadata calculation is automatically triggered by the actions described above.|
Enable File List Indexing
|When set, RPM metadata calculation will also include indexing the |
RPM Group File Names
A comma-separated list of YUM group files associated with your RPM packages.
Note that at each level (depth), the
Artifactory remote repositories support RPMs out-of-the-box, and there no need for any special configuration needed in order to work with RPMs in a remote repository.
All you need to do is point your YUM client at the remote repository, and you are ready to use YUM with Artifactory.
To define a remote repository to proxy an RPM remote repository, follow the steps below:
- In the Admin module under Repositories | Remote, click "New" to create a new remote repository.
- Set the Repository Key value, and specify the URL to the remote repository in the URL field as displayed below.
- Click "Save & Finish"
- Back in the Artifacts module, in theTree Browser, select the repository. Note that in the Tree Browser, the repository name is appended with "-cache".
- Click Set Me Up and copy the value of the baseurl tag.
- Next, create the
targetCentos.repofile and paste the following configuration into it:
A Virtual Repository defined in Artifactory aggregates packages from both local and remote repositories.
This allows you to access both locally hosted RPM packages and remote proxied RPM repositories from a single URL defined for the virtual repository.
To define a virtual YUM repository, create a virtual repository, set the Package Type to be RPM, and select the underlying local and remote RPM repositories to include in the Basic settings tab.
To allow deploying packages to this repository, set the Default Deployment Repository.
Signing RPM Metadata
Artifactory supports using a GPG key to sign RPM metadata for authentication by the YUM client.
To generate a pair of GPG keys and upload them to Artifactory, please refer to GPG Signing.
Installing RPM Packages Using Yum
After configuring the
rpm-local repository in Artifactory, you need to configure your local machine to install software packages from it by executing the following steps:
artifactory.repofile with root privileges
Paste the following configuration into the
Now, every RPM file deployed to the root of the
rpm-local repository can be installed using:
Deploying RPM Packages
For example, to deploy an RPM package into a repository called
rpm-local you could use the following:
where PATH_TO_METADATA_ROOT specifies the path from the repository root to the deploy folder.
Deploying RPM Modules to Your Local Repository
You can deploy RPM modules to the
repodata folder using the
modules.yaml file which contains all the desired modules and then proceed to trigger a repository index to update the
repomd.xml and other metadata files with the modules information.
You can perform the upload directly in the JFrog Platform UI or using the following command.
curl -u <USERNAME>:<PASSWORD> -XPUT
"http://localhost:8081/artifactory/rpm-local/<PATH_TO_REPODATA_FOLDER>/modules.yaml -T <TARGET_MODULES_FILE_PATH>"
- Trigger the reindex by running the Calculate YUM Repository Metadata API.
A YUM group is a set of RPM packages collected together for a specific purpose. For example, you might collect a set of "Development Tools” together as a YUM group.
A group is specified by adding a group XML file to same directory as the RPM packages included in it. The group file contains the metadata of the group including pointers to all the RPM files that make up the group.
A group file can also be created by running the following command:
Attaching a YUM Group
The process of attaching YUM group metadata to a local repository is simple:
- Create an XML file in the groups format used by YUM. You can either just type it out manually using any text editor, or run the
- Deploy the created group file to the
Artifactory will automatically perform the following steps:
- Create the corresponding
.gzfile and deploy it next to the deployed group XML file.
- Invoke a YUM calculation on the local repository.
- Attach the group information (both the XML and the
.gzfile) to the
- Create the corresponding
- Make sure the group file names are listed in the YUM Group File Names field under the Basic tab of the repository configuration. This tells Artifactory which files should be attached as repository group information.
YUM Group Commands
The following table lists some useful YUM group commands:
|Install the YUM group. The group must be deployed to the root of the YUM local repository.|
|Remove the RPM group|
Update the RPM group. The group must be deployed to the root of the YUM local repository.
|List the RPM packages within the group.|
|List the YUM groups|
Setting Group Properties
YUM group properties can be set in the
/etc/yum.config file as follows:
|overwrite_groups||0 or 1|
Determines YUM's behavior if two or more repositories offer package groups with the same name.
If set to 1 then the group packages of the last matching repository will be used.
If set to 0 then the groups from all matching repositories will be merged together as one large group.
|groupremove_leaf_only||0 or 1|
Determines YUM's behavior when the groupremove command is run.
If set to 0 (default) then all packages in the group will be removed.
If set to 1 then only those packages in the group that aren't required by another package will be removed.
|enable_group_conditionals||0 or 1|
Determines whether YUM will allow the use of conditionals packages.
If set to 0 then conditionals are not allowed
If set to 1 (default) package conditionals are allowed.
|group_package_types||optional, default, mandatory||Tells YUM which type of packages in groups will be installed when |
Proxy Server Settings
If your organization uses a proxy server as an intermediary for Internet access, specify the
proxy settings in
/etc/yum.conf. If the proxy server also requires authentication, you also need to specify the
If you use the yum plugin (
yum-rhn-plugin) to access the ULN, specify the
httpProxy settings in
/etc/sysconfig/rhn/up2date. In addition, If the proxy server requires authentication, you also need to specify the
proxyPassword settings as shown below.
YUM supports SSL from version 3.2.27.
To secure a repository with SSL, execute the following steps:
- Generate a private key and certificate using OpenSSL.
Define your protected repository in a
.repofile as follows:
gpgkey is a URL pointing to the ASCII-armored GPG key file for the repository . This option is used if YUM needs a public key to verify a package and the required key has not been imported into the RPM database.
If this option is set, YUM will automatically import the key from the specific URL. You will be prompted before the key is installed unless the assumeyes option is set.
Using Yum Variables
You can use and reference the following built-in variables in
yum commands and in all YUM configuration files (i.e.
/etc/yum.conf and all
.repo files in the
