I'm a bit lost over here,
could anyone point me to the right documentation to use the
Irmin backend for Canopy instead of using a Git repository?
I have started my local Irmin Git backend (irmin init -d -v -s
git) on the directory which contains my Canopy content
(~/irmin-canopy-data), perhaps what I'm missing is the right
remote uri path on the config.ml file, currently using "http://127.0.0.1:8080/read/home/carlos/irmin-canopy-data/.git".
When I run the unikernel
and try to pull the canopy content I get the following error:
~/workspace/Canopy$ ./mir-canopy -r
http://127.0.0.1:8080/read/home/carlos/irmin-canopy-data/.git -l
