How to test …

This page should explain how to test given features in Nextcloud.

Email sending

docker run -d -p 1025:1025 -p 8025:8025 mailhog/mailhog
occ config:system:set mail_smtpmode --value=smtp
occ config:system:set mail_smtphost --value=
occ config:system:set mail_smtpport --value=1025 --type=integer

Then after having Nextcloud send some emails, open to view them.


First you need to install the phpredis extension . There is a install document available inside the repo and many linux distribtutions ship it in their repositories as well.

pecl install redis

Redis Cluster

For a local Redis cluster setup there are some docker script collected in this repository. It boils down to clone the repo and run make up. Then the redis cluster is available at localhost:7000.

Following config.php can be used:

'memcache.distributed' => '\OC\Memcache\Redis',
'redis.cluster' => [
   'seeds' => [ // provide some/all of the cluster servers to bootstrap discovery, port required
   'timeout' => 0.0,
   'read_timeout' => 0.0,
   'failover_mode' => \RedisCluster::FAILOVER_ERROR,

Primary object store with S3

docker run -p 9000:9000 minio/minio server /data

The edit config.php and add the following section:

'objectstore' =>
    array (
        'class' => 'OC\\Files\\ObjectStore\\S3',
        'arguments' =>
        array (
            'bucket' => 'nextcloud-dev',
            'key' => 'minioadmin',
            'secret' => 'minioadmin',
            'hostname' => 'localhost',
            'port' => '9000',
            'use_ssl' => false,
            'use_path_style' => true,

S3 external storage

occ app:enable files_external

docker run -p 9000:9000 minio/minio server /data

Then add an external storage in the web UI using the following configuration:

  • Authentication type: Access key

  • Access key: minioadmin

  • Secret key: minioadmin

  • Bucket: nextcloud-dev

  • Hostname: localhost

  • Port: 9000

  • Region: leave empty

  • Enable path style: yes

SMB external storage

occ app:enable files_external

mkdir /tmp/samba
docker run -it -p 139:139 -p 445:445 \
    -v /tmp/samba:/smbmount dperson/samba \
    -u "user;password" -s "public;/smbmount;yes;no;yes"

Make sure that smbclient is installed on your Nextcloud server and has the following configuration:

# /etc/samba/smb.conf
client min protocol = SMB2
client max protocol = SMB3
hide dot files = no

The setup can be verified with

smbclient // -u user

SAML setup with onelogin

Collabora without SSL

1) Start Collabora in a docker container

docker run -p -e 'domain=' \
    -e 'username=admin' -e 'password=487903ffcf4' \
    -e extra_params='--o:ssl.enable=false' \
    --restart always --cap-add MKNOD collabora/code
  • is localhost, which is default by Docker

  • get IP of Collabora container: docker inspect –format=’{{ .NetworkSettings.IPAddress }}’ $containerName

2) Configure Nextcloud
  • go to your local cloud (e.g. -> Settings -> Collabora
    • set URL to IP you found out above, e.g:

    • check “Disable certificate verification (insecure)

3) Use
  • please note that you cannot use it with localhost, but you have to enter a valid IP address of localhost

  • with this approach you can also use it with mobile clients

4) Troubleshoot
{"convert-to":{"available":false},"hasMobileSupport":true,"hasTemplateSaveAs":true,"productName":"Collabora Online Development Edition"}


  1. Create self signed cert, should be on a permanent path:

    mkdir -p /tmp/oo/certs
    cd /tmp/oo/certs
    openssl genrsa -out onlyoffice.key 4096
    openssl req -new -key onlyoffice.key -out onlyoffice.csr
    openssl x509 -req -days 3650 -in onlyoffice.csr -signkey onlyoffice.key -out onlyoffice.crt
    openssl dhparam -out dhparam.pem 4096
    chmod 400 onlyoffice.key
    chmod 400 onlyoffice.crt
    chmod 400 onlyoffice.csr
    chmod 400 dhparam.pem
  2. Start docker, important: do not use certs folder, but parent folder:

    docker run --name=ONLYOFFICEDOCKER -i -t -d -p 4433:443 \
    -e JWT_ENABLED='true' -e JWT_SECRET='secret' --restart=always \
    -v /tmp/oo/:/var/www/onlyoffice/Data onlyoffice/documentserver
  3. Go into docker container:

    • docker exec -it ONLYOFFICEDOCKER /bin/bash

    • apt-get update

    • apt-get install vim -y

    • vim /etc/onlyoffice/documentserver/default.json
      • change rejectUnauthorized to false

    • vim /etc/onlyoffice/documentserver/local.json
      • change token -> inbox -> header to “AuthorizationJWT”

      • change token -> outbox -> header to “AuthorizationJWT”

    • Add the following to your config.php

    'onlyoffice' => array (
        'verify_peer_off' => true,
        'jwt_secret' => 'secret',
        'jwt_header' => 'AuthorizationJWT'
Test with local ip: https://localhost:4433
  • accept cert warning

  • verify that “Document Server is running” is shown

Test with Nextcloud
  • download & enable OnlyOffice app

  • configure:

WebAuthn without SSL

Chrome has the option to test WebAuthn with a fake device. Browsers support WebAuthn on HTTPS protected sites and localhost domains. Unfortunately this is not supported by the used PHP library where the check for HTTPS needs to be commented for testing on non-HTTPS localhost development environments.
