Conda Package Match Specification

Conda supports to specify channel where the package is sourced from and match specification of the package. So we can specify images more specifically.

The syntax is

(channel(/subdir):(namespace):)name(version(build))[key1=value1,key2=value2]

For example, to install numpy package which is sourced from the channel, conda-forge, Ref.⇗.

Use -c conda-forge:: to specify the channel:

-c conda-forge::numpy==1.17*

Building in progress

While building, the image name is amended with an triangular exclamation mark to indicate the image is not ready.

Click the image name to view the detail, it shows Image building in progress beside Container image url.

Click Image building in progress to view the Build Details and Log of the building.

The building progress can be cancelled by Cancel Build.

View build details and Rebuild

Once the building finishes successfully, there is no triangular exclamation mark as a postfix to the image name. The image becomes available from image selection.

Click View build details to view the detail and logs or to modify the detail for rebuilding.
