I am trying to install a local Docker image of CoCalc, however, I'd like to keep using Sage-8.9 with Python2. Following the github instructions, I run

docker run --name=cocalc -d -v ~/cocalc:/projects -p 443:443 sagemathinc/cocalc

which results in Sage-9.1, so all my code stops working. How do I switch to Sage-8.9 with docker?

I found the following solution:

docker run --name=cocalc -d -v ~/cocalc:/projects -p 443:443 sagemathinc/cocalc:67b7e8dece16

by viewing the "sagemathinc/cocalc" tags on But I don't know if this solution is permanent enough -- the tags listed there are only for the past 10 months

Hi, I think the best solution is to fork the dockerfile configuration and modify the part that setups sage. In the git history, earlier revisions should show how 8.9 was built or well, more recent versions might build for python 2 as well. For more detailed support: license and support paragraph
