Scripting mass app installation with occ or a compose file

Hey, wondering what the best way would be to export my installed app list so I can script installation as opposed to locating, installing and enabling the same 40 apps from the webui appstore.

I see the /apps directory for www-data and was curious how others are handling this.


Am I correct in assuming that you want a list of the installed apps that you can then use in a script on a fresh installation to batch install them there?

If yes, read ahead, if not, please ignore.

As you know, the output of

occ app:list

is a nice source of information but not an output ready for further use in a script.

In addition, you probably want to have the pre-installed apps excluded from the output.

To get a script useable output with the occ query, we need the command-line JSON processor jq
If not yet installed:

apt install jq

And this is the jq-string to get only the activated aps, without the preinstalled apps:

## preinstalled apps, maintain this list by hand:
exclude_list='["admin_audit", "cloud_federation_api", "comments", "contactsinteraction",
    "dashboard", "dav", "encryption", "federatedfilesharing", "federation", "files",
    "files_external", "files_sharing", "files_trashbin", "files_versions",
    "lookup_server_connector", "oauth2", "provisioning_api", "settings", "sharebymail",
    "systemtags", "testing", "theming", "twofactor_backupcodes", "updatenotification",
    "user_ldap", "user_status", "weather_status", "workflowengine"]' 

## how do we call occ:
# change the webserver-user accordingly
# change path accordingly:
occ_call="sudo -u $ht_user php -f /var/www/nextcloud/occ"

# your enabled apps
my_enabled_apps="$($occ_call app:list --output=json |
                  jq --argjson exclude_list "$exclude_list" '.enabled |
                  keys[] | select(. as $app |
                  ($exclude_list |
                  index($app) | not)) |
                  @text' | jq -s 'join(" ")')"

# your disabled apps
my_disabled_apps="$($occ_call app:list --output=json |
                  jq --argjson exclude_list "$exclude_list" '.disabled |
                  keys[] | select(. as $app |
                  ($exclude_list |
                  index($app) | not)) |
                  @text' | jq -s 'join(" ")')"

# all your apps
my_apps="$my_enabled_apps $my_disabled_apps"

# now you can write it in a file for further use:

echo "$my_apps" > (path/to/)my_apps.txt

You now will have a list of installed apps in one row, separated by spaces, which you can use in a script on your new nextcloud like this:

# in your newly created virtual machine with your fresh installed nextcloud:
# add/change path accordingly:
my_apps="$(cat $my_apps_file)"

# pic the options you want, -n looks like a good idea to me:
#      --keep-disabled   don't enable the app afterwards
#  -f, --force           install the app regardless of the Nextcloud version requirement
#      --allow-unstable  allow installing an unstable releases
#  -q, --quiet           Do not output any message
#  -V, --version         Display this application version
#  -n, --no-interaction  Do not ask any interactive question

# now let occ do the work, without you getting RSI-Syndrom ;)

for app_id in $my_apps; do
    $occ_call app:install $occ_opts -- $app_id;

As you may have noticed, you can work solely with the enabled apps list as well if you want that. It is all to you and your requirements.

I hope I could help
