Deploying KeyDB with Volume: Permission Denied Issue

Hello! I'm having trouble deploying keydb with a volume. It keeps giving me an error saying 'Permission denied /volume/path'. I tried setting RAILWAY_RUN_UID and checked the current user (which turned out to be root), but keydb still throws a permissions error. I also checked with ls -l / and confirmed that the volume exists. I even tried renaming it (changing volume path), but nothing worked. Can someone please help me fix this? Dockerfile:

FROM eqalpha/keydb

COPY keydb.conf /etc/keydb/keydb.conf

EXPOSE 6379

CMD ["keydb-server", "/etc/keydb/keydb.conf", "--requirepass", "$KEYDB_PASSWORD"]

FROM eqalpha/keydb

COPY keydb.conf /etc/keydb/keydb.conf

EXPOSE 6379

CMD ["keydb-server", "/etc/keydb/keydb.conf", "--requirepass", "$KEYDB_PASSWORD"]

what did you set RAILWAY_RUN_UID to?

abdulrahman1s•3mo ago

0 I've spent an hour searching for a solution, checking KeyDB docs, their Docker build images, everything. I'm feeling pretty hopeless about it. If you can manage to solve this issue, it would be wonderful.

where are you mounting the volume?

abdulrahman1s•3mo ago

/keydb_data

Brody•3mo ago

send the conf file please

abdulrahman1s•3mo ago

port 6379
storage-provider flash /keydb_data
save ""
logfile ""
maxmemory 100mb
maxmemory-policy allkeys-random
maxclients 10
loglevel notice
always-show-logo no

port 6379
storage-provider flash /keydb_data
save ""
logfile ""
maxmemory 100mb
maxmemory-policy allkeys-random
maxclients 10
loglevel notice
always-show-logo no

are these things configurable via environment variables?

abdulrahman1s•3mo ago

I don't think so. keydb can be configured via a config file or parameters passed to its executable as stated by their docs.

cool, will take a crack at this

I made a small adjustment to the start command by adding "--storage-provider flash /volume/path", and it worked perfectly. Thanks a lot! You're awesome! I'm not sure what mistake I made, though. If you have any insights on what went wrong so I can avoid it next time, that would be fantastic.

why flash?

abdulrahman1s•3mo ago

I needed a cheaper alternative to Redis that still uses the Redis protocol. So, I discovered KeyDB on Flash, which saves on costs by limiting RAM usage and storing data on disk.

Brody•3mo ago

oh so with flash no data ever gets saved into memory

abdulrahman1s•3mo ago

KeyDB still uses RAM for hot keys, but you can control how much it uses by using the 'maxmemory' option.

Brody•3mo ago

what did you set the path for flash to?

abdulrahman1s•3mo ago

To the volume path

Brody•3mo ago

/data?

abdulrahman1s•3mo ago

I've changed the path to something else. I don't quite remember the reason. 😅
