When Artifactory is installed by Helm, the latest version is installed by default. However, if you don't want to install the latest version (e.g. The version which has been used on the staging environment is also needed on the production one, but the latest version is released during the feasibility study on the staging one), it can be installed by the --set flags.
The following is an example of how to install Artifactory Pro 7.2.1.
$ helm install artifactory --set artifactory.image.version=7.2.1 --set nginx.image.version=7.2.1 jfrog/artifactory
