Owncloud docker port

i was able to get owncloud running with docker …
Have 2 questions .

On machine i have it i have something else running on port 80, how can i change this owncloud image to run on another port .

Second question . What is the best way to move my old owncloud installed regularly on my old pi to this docker installation and i can i set so the data file i on my device and not on the image

ownCloud server itself is running on port 8080 inside the docker container.
I would recommend to only expose the port and put a SSL terminating reverse proxy in front of it. That reverse proxy would have port 80 and 443 published, while ownCloud has no ports published.

I would spin up an ownCloud container in the same oC version as your RPi setup and look at the configuration and data directories.
Go to the RPi move the data directory to the same as inside the docker container: https://doc.owncloud.org/server/10.2/admin_manual/maintenance/manually-moving-data-folders.html

Then test-migrate the installation into the docker container. You could easily spin up a test container and try this process several times, until you have figured out all configuration details.

Make sure to remove all details of the previous containers (volumes, …) , when starting over.

Once it is all running, you can do a final migration.

This ownCloud image is designed to work with a data volume in the host filesystem and with separate MariaDB and Redis containers.

MariaDB [owncloud]> select * from oc_storages;
±------------------------±-----------±----------±-------------+
| id | numeric_id | available | last_checked |

2 rows in set (0.002 sec)

can i leave as is

Depends on what you want to achieve…

I wouldn’t try to change much in the docker container itself, I would recommend to change your RPi installation to match the docker setup.

If you want to know for sure, you just have to spin up a docker container environment and look inside the database for the value and compare it to the value you have in your RPi env.

so i did the following

i copied data directories

then i imported the db to new instance …

im able to log in but i notice two things

no file preview
and calendar names are there but no event copied .(same in old instance hmmmmm)

i guess migrating is not a good idea

i will export calendar and perhaps copy files

Thanks

have a question , in a regular install the apps directory is in owncloud/

while in a docker instalation the apps is in /mnt/data ?

so when migrating should i move old apps to data/

You’re saying you can’t see any files? Are you still in single-user mode?
Have you made sure the file permissions are correct?

Yes, this is what you should do.

thanks i see the files took long to show up …

“Then, copy only your data, configuration, and database files from your original ownCloud instance to the new machine.”

which are the database files? = importing the db?

Correct, run a mysqldump on the source machine and reimport that dump on the target machine, or in your case in the docker container.
