ISLE is a community project that uses replaceable Docker images to streamline and largely automate the process of installing and maintaining the entire Islandora 7.x stack, while at the same time enabling institutions to create customizations that persist separately from core code. The result is the ability to easily, quickly and regularly update an institution’s entire Islandora stack. Maintaining ISLE requires significantly less time and staff, and also reduces the dependency on expert technical staff and outside vendors.
