OCM tutorial seems incomplete

[michielbdejong]

The step that is supposed to demonstrate Accessing the share seems to be incomplete. It ends with Accessing the list of shares and the tutorial does not show how Marie can get access to the "Example file" text that Einstein uploaded.

[michielbdejong]

The sending side does have ocdav enabled and there is a dataprovider service which I guess must be the "Data server" to which the file gets uploaded.

Hm

Maybe the tutorial is not even working with the latest revad versions, or maybe this error is due to something that's specific to the ocm-test-suite image and config. I'll try running it with the exact config from examples/ocmd

[michielbdejong]

docker run -d --network=testnet --name=ocmd-server-1.docker -e HOST=ocmd-server-1 -v /root/michiel-dev/reva:/reva revad sleep 300000
docker exec -it ocmd-server-1.docker /bin/bash
$ cd /reva 
$ export PATH=$PATH:/usr/local/go/bin
$ go mod vendor
$ make deps
$ make build-revad
$ make build-reva
$ cd /etc/revad
$ /reva/cmd/revad/revad -c ocmd-server-1.toml 
docker exec -it ocmd-server-1.docker /reva/cmd/reva/reva -insecure -host=localhost:19000

And

docker run -d --network=testnet --name=ocmd-server-2.docker -e HOST=ocmd-server-2 -v /root/michiel-dev/reva:/reva revad
docker exec -it ocmd-server-2.docker /reva/cmd/reva/reva -insecure -host=localhost:17000

Working on this in https://github.com/cs3org/ocm-test-suite/tree/revad-edge-testing since I want to use the exact filenames as the tutorial and users/providers.demo.json have been edited in the main branch of the ocm-test-suite.

[michielbdejong]

-> #3365

[michielbdejong]

-> cs3org/ocm-test-suite#63

[michielbdejong]

Note: The upload should be done to some path under /home/ and you need to
mkdir -p /var/tmp/reva/data/einstein/home
on the revad server first.

In the tutorial it says to mkdir /home/my-folder first, will try if that also works.

[michielbdejong]

No, that step fails if /var/tmp/reva/data/einstein/home doesn't exist:

>> mkdir /home/my-folder
error: code=CODE_NOT_FOUND msg="path not found when creating container" support_trace="ffd1f60b92a7582c0e490252ad34c367"

Testing this how with Nextcloud->Reva->Reva->Nextcloud configuration.

Debugging this more in pondersource/sciencemesh-php#102
Once that is working we can also show it in the ocmd tutorial.
