sigil

Description

Sigil is the hub of the Great Wheel, a city at the center of the Outlands, the most balanced of neutral areas at the center of the planes. Also known as the "City of Doors" for the multitude of portals to other planes of existence and the Cage since those portals are the only way in or out, it is the setting for most of Planescape: Torment.

Sigil is an AWS SSM Session manager client. Allowing access to EC2 instances without exposing any ports.

To run specific build use:

bazelisk build --config cross:[darwin|linux|windows]_amd64 :[dev|release]

for working Docker image:

bazelisk build --config cross:linux_amd64 :[dev|release]-image

Container image
