Overview

To simplify access to different repositories, Artifactory allows you to define a virtual repository which is a collection of local, remote and other virtual repositories accessed through a single logical URL.

A virtual repository hides the access details of the underlying repositories letting users work with a single, well-known URL. The underlying participating repositories and their access rules may be changed without requiring any client-side changes.

Basic Settings

The following are fully described in theCommon Settingspage.

Basic Settings

In addition, in theRepositoriessection of theBasicsettings screen youselect theAvailable Repositoriesyou want to include in the new virtual repository and move them to theSelected Repositorieslist.

This list can be re-ordered by dragging and dropping within theSelected Repositorieslist.

Included Repositories

TheIncluded Repositoriessection displays the effective list of actual repositories included in this virtual repository. If any of the available repositories you have selected are themselves virtual repositories, then theIncluded Repositoriessection will display the local and remote repositories included within them. TheIncluded Repositorylist is automatically updated in case any of the nested virtual repositories change.

The search/resolution order when requesting artifacts from a virtual repository is always:

  1. Local repositories
  2. Remote repository caches
  3. Remote repositories themselves.

The order within these categories is controlled by the order they are presented in theSelected Repositorieslist.

Nesting

在Artifactory和fac嵌套是一个独特的特性ilitates more flexibility in using virtual repositories.

You should take care not to create an "infinite loop" of nested repositories. Artifactory analyzes the internal composition of virtual repositories and will issue a warning if the virtual repository can not be resolved due to invalid nesting.

Using Includes and Excludes Patterns

The ability to define andIncludes Patternand anExcludes Patternfor virtual repositories (especially when nesting is used) provides a powerful tool you can use to manage artifact requests in your organization.

For example, your organization may have its own artifacts which are hosted both internally in a local repository, but also in a remote repository. For optimal performance, you would want these artifacts to be accessed from the local repository rather than from the remote one. To enforce this policy, you can define a virtual repository called "remote-repos" which includes the full set of remote repositories accessed by your organization, and then specify an Excludes Pattern with your organization's groupID. in this way, any attempt to access your internal artifact from a remote repository would be rejected.

Consider another example in which you wish to define a virtual repository for your developers, however you wish to keep certain artifacts hidden from them. This could be achieved by defining anExcludes Patternbased on groupId, source or version.


Deploying to a Virtual Repository

From version 4.2, Artifactory supports deploying artifacts to a virtual repository. For example you can now usedocker push, npm publish, NuGet push, gem pushArtifactory's REST API and more to deploy packages to a virtual repository.

For more details, please refer toDeploying Artifacts.


Advanced Settings

Virtual Repository Advanced Settings

Artifactory Requests Can Retrieve Remote Artifacts
An Artifactory instance may request artifacts from a virtual repository in another Artifactory instance. This checkbox specifies whether the virtual repository should search through remote repositories when trying to resolve an artifact requested by another Artifactory instance. For example, you can use this feature when Artifactory is deployed in a mesh (grid) architecture, and you do not want all remote instances of Artifactory to act as proxies for other Artifactory instances.

Maven, Gradle, Ivy and SBT Repositories

In addition to the above checkbox, these repository types offer the followingAdvancedsettings:

Cleanup Repository References in POMs

Public POMs may include direct references to external repositories. If either of the below code samples are present in the POM, Maven dynamically adds an external repository URL to the build which circumvents Artifactory.

 or 

A client side solution for this is to use mirrorOf. For details please refer toAdditional "Mirror-any" Setup.

This setting gives you the ability to ensure Artifactory is the sole provider of Artifacts in your system by automatically cleaning up the POM file. The three values available for this setting are:

Discard Active References
Removes repository elements that are declared directly under project or under a profile in the same POM that isactiveByDefault
Discard Any References
Removes all repository elements regardless of whether they are included in an active profile or not
Nothing
Does not remove any repository elements declared in the POM
Key Pair

指定密钥对to use for automatically signing artifacts.

Please refer toWebStart and Jar Signing.
