Error "library initialization failed - unable to get max # of allocated fds" on starting swarmpit_app container

[chrismueller]

Unfortunatelly the "swarmpit_app" container is not starting . Log message: "library initialization failed - unable to get max # of allocated fds"

I'm running docker swarm on 2 Raspberry PI 4 (8GB) on Ubuntu 20.04 server 64bit For creating the swarmpit stack I used the arm docker compose file out of the repository.

Server Version: 19.03.8 Kernel Version: 5.4.0-1011-raspi Operating System: Ubuntu 20.04 LTS OSType: linux Architecture: aarch64 CPUs: 4 Total Memory: 7.628GiB

I get the same problem on Raspberry PI 4 (4GB) with Ubuntu 20.04 server 64bit

@lumir-mrkva can you check pls ?

[chrismueller]

Within the ARM compose file the treehouses/couchdb image can be replaced with the official couchdb image. (This is meanwhile available for arm64/v8)

Seeing this also on ubuntu 20.04, using the official couchdb image.

in the logs I'm seeing this from couchdb: db_1 | [error] 2020-06-21T18:29:17.543685Z nonode@nohost emulator -------- Error in process <0.1287.0> with exit value: db_1 | {database_does_not_exist,[{mem3_shards,load_shards_from_db,"_users",[{file,"src/mem3_shards.erl"},{line,395}]},{mem3_shards,load_shards_from_disk,1,[{file,"src/mem3_shards.erl"},{line,370}]},{mem3_shards,load_shards_from_disk,2,[{file,"src/mem3_shards.erl"},{line,399}]},{mem3_shards,for_docid,3,[{file,"src/mem3_shards.erl"},{line,86}]},{fabric_doc_open,go,3,[{file,"src/fabric_doc_open.erl"},{line,39}]},{chttpd_auth_cache,ensure_auth_ddoc_exists,2,[{file,"src/chttpd_auth_cache.erl"},{line,195}]},{chttpd_auth_cache,listen_for_changes,1,[{file,"src/chttpd_auth_cache.erl"},{line,142}]}]}

and swarmpit is reporting: library initialization failed - unable to get max # of allocated fds

Possibly related to this? https://github.com/seccomp/libseccomp/commit/7780b0853eff8521bbf79611656c68fadc1dab3d

[ruby-dev]

I was able to get this running on Ubuntu 20.04 arm64 on a raspberry pi 4 by doing the following.

1. sudo apt-get install libseccomp-dev
2. Adding the environment variables to the couchdb container in docker-compose COUCHDB_USER=admin COUCHDB_PASSWORD=password
3. Changing the connection string to include the user and password to the swarmpit container in docker-compose

[chrismueller]

I can confirm. With these changes swarmpit is running fine on Ubuntu 20.04 on the PI 4. Thanks Dustin.

[nohaapav]

Can you submit PR for the fix please ?

[ruby-dev]

Can you submit PR for the fix please ?

I can. I will get it done sometime tommorrow.
