OpenProject advanced configuration

OpenProject can be configured either via the config/configuration.yml file, environment variables or a mix of both. While the latter is probably a bad idea, the environment variable option is often helpful for automatically deploying production systems. Using the configuration file is probably the simplest way of configuration.

You can find a list of options below and an example file in config/configuration.yml.example

Environment variables

Configuring OpenProject through environment variables is detailed in this separate guide.

List of options

• attachments_storage_path
• autologin_cookie_name (default: 'autologin'),
• autologin_cookie_path (default: '/')
• autologin_cookie_secure (default: false)

• scm_subversion_command (default: 'svn')
• scm_local_checkout_path (default: 'repositories')
• force_help_link (default: nil)
• session_store: active_record_store, cache_store, or cookie_store (default: cache_store)
• drop_old_sessions_on_logout (default: true)
• drop_old_sessions_on_login (default: false)
• auth_source_sso (default: nil)
• omniauth_direct_login_provider (default: nil)
• disable_password_login (default: false)
• attachments_storage (default: file)
• direct_uploads (default: true)
• fog_download_url_expires_in (default: 21600)
• hidden_menu_items (default: {})
• disabled_modules (default: [])

Setting session options

Use session_store to define where session information is stored. In order to store sessions in the database and use the following options, set that configuration to :active_record_store.

Delete old sessions for the same user when logging in (Disabled by default)

To enable, set the configuration option drop_old_sessions_on_login to true.

Delete old sessions for the same user when logging out (Enabled by default)

To disable, set the configuration option drop_old_sessions_on_logout to false.

disable password login

default: false

If you enable this option you have to configure at least one omniauth authentication provider to take care of authentication instead of the password login.

All username/password forms will be removed and only a list of omniauth providers presented to the users.

auth source sso

default: nil

Example:

auth_source_sso:
  header: X-Remote-User
  
  # Optional secret to be passed by the header in form
  # of a colon-separted userinfo string
  # e.g., X-Remote-User "username:s3cret"
  secret: s3cr3t
  # Uncomment to make the header optional.
  # optional: true

Can be used to automatically login a user defined through a custom header sent by a load balancer or reverse proxy in front of OpenProject, for instance in a Kerberos Single Sign-On (SSO) setup via apache. The header with the given name has to be passed to OpenProject containing the logged in user and the defined global secret as in $login:$secret.

omniauth direct login provider

default: nil

Example:

omniauth_direct_login_provider: google

Per default the user may choose the usual password login as well as several omniauth providers on the login page and in the login drop down menu. With his configuration option you can set a specific omniauth provider to be used for direct login. Meaning that the login provider selection is skipped and the configured provider is used directly instead.

If this option is active /login will lead directly to the configured omniauth provider and so will a click on 'Sign in' (as opposed to opening the drop down menu).

Note that this does not stop a user from manually navigating to any other omniauth provider if additional ones are configured.

Gravatar images

OpenProject uses gravatar images with a 404 fallback by default to render an internal, initials-based avatar. You can override this behavior by setting gravatar_fallback_image to a different value to always render Gravatars

For supported values, please see https://en.gravatar.com/site/implement/images/

Attachments storage

You can modify the folder that attachments are stored locally. Use the attachments_storage_path configuration variable for that. But ensure that you move the existing paths. To find out the current path on a packaged installation, use openproject config:get ATTACHMENTS_STORAGE_PATH.

To update the path, use openproject config:set ATTACHMENTS_STORAGE_PATH="/path/to/new/folder". Ensure that this is writable by the openproject user.

attachment storage type

default: file

Attachments can be stored using fog as well. You will have to add further configuration through fog, e.g. for Amazon S3:

attachments_storage: fog
fog:
  directory: bucket-name
  credentials:
    provider: 'AWS'
    aws_access_key_id: 'AKIAJ23HC4KNPWHPG3UA'
    aws_secret_access_key: 'PYZO9phvL5IgyjjcI2wJdkiy6UyxPK87wP/yxPxS'
    region: 'eu-west-1'

In order to set these values through ENV variables, use:

<pre>
OPENPROJECT_ATTACHMENTS__STORAGE=fog
OPENPROJECT_FOG_CREDENTIALS_AWS__ACCESS__KEY__ID="AKIAJ23HC4KNPWHPG3UA"
OPENPROJECT_FOG_CREDENTIALS_AWS__SECRET__ACCESS__KEY="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"
OPENPROJECT_FOG_CREDENTIALS_PROVIDER=AWS
OPENPROJECT_FOG_CREDENTIALS_REGION="eu-west-1"
OPENPROJECT_FOG_DIRECTORY=uploads
</pre>

backend migration

You can migrate attachments between the available backends. One example would be that you change the configuration from the file storage to the fog storage. If you want to put all the present file-based attachments into the cloud, you will have to use the following rake task:

rake attachments:copy_to[fog]

It works the other way around too:

rake attachments:copy_to[file]

Note that you have to configure the respective storage (i.e. fog) beforehand as described in the previous section. In the case of fog you only have to configure everything under fog, however. Don't change attachments_storage to fog just yet. Instead leave it as file. This is because the current attachments storage is used as the source for the migration.

direct uploads

default: true

When using fog attachments uploaded in the frontend will be posted directly to the cloud rather than going through the OpenProject servers. This allows large attachments to be uploaded without the need to increase the client_max_body_size for the proxy in front of OpenProject. Also it prevents web processes from being blocked through long uploads.

If, for what ever reason, this is undesirable, you can disable this option. In that case attachments will be posted as usual to the OpenProject server which then uploads the file to the remote storage in an extra step.

Note: This only works for S3 right now. When using fog with another provider this configuration will be false. The same goes for when no fog storage is configured, or when the use_iam_profile option is used in the fog credentials when using S3.

fog download url expires in

default: 21600

Example:

fog_download_url_expires_in: 60

When using remote storage for attachments via fog - usually S3 (see attachments_storage option) - each attachment download will generate a temporary URL. This option determines how long these links will be valid.

The default is 21600 seconds, that is 6 hours, which is the maximum expiry time allowed by S3 when using IAM roles for authentication.

Overriding the help link

You can override the default help menu of OpenProject by specifying a force_help_link option to the configuration. This value is used for the href of the help link, and the default dropdown is removed.

Setting an impressum (legal notice) link

You can set a impressum link for your OpenProject instance by setting impressum_link to an absolute URL.

hidden menu items

default: {}

You can disable specific menu items in the menu sidebar for each main menu (such as Administration and Projects). The following example disables all menu items except 'Users', 'Groups' and 'Custom fields' under 'Administration':

hidden_menu_items:
  admin_menu:
    - roles
    - types
    - statuses
    - workflows
    - enumerations
    - settings
    - ldap_authentication
    - colors
    - project_types
    - export_card_configurations
    - plugins
    - info

The configuration can be overridden through environment variables. You have to define one variable for each menu. For instance 'Roles' and 'Types' under 'Administration' can be disabled by defining the following variable:

OPENPROJECT_HIDDEN__MENU__ITEMS_ADMIN__MENU='roles types'

blacklisted routes

default: []

You can blacklist specific routes The following example forbid all routes for above disabled menu:

blacklisted_routes:
  - 'admin/info'
  - 'admin/plugins'
  - 'export_card_configurations'
  - 'project_types'
  - 'colors'
  - 'settings'
  - 'admin/enumerations'
  - 'workflows/*'
  - 'statuses'
  - 'types'
  - 'admin/roles'

The configuration can be overridden through environment variables.

OPENPROJECT_BLACKLISTED__ROUTES='admin/info admin/plugins'

disabled modules

default: []

Modules may be disabled through the configuration. Just give a list of the module names either as an array or as a string with values separated by spaces.

Array example:

disabled_modules:
  - backlogs
  - meetings

String example:

disabled_modules: backlogs meetings

The option to use a string is mostly relevant for when you want to override the disabled modules via ENV variables:

OPENPROJECT_DISABLED__MODULES='backlogs meetings'

local checkout path

default: "repositories"

Remote git repositories will be checked out here.

APIv3 basic auth control

default: true

You can enable basic auth access to the APIv3 with the following configuration option:

apiv3_enable_basic_auth: true

global basic auth

default: none

You can define a global set of credentials used to authenticate towards API v3. Example section for configuration.yml:

default:
  authentication:
    global_basic_auth:
      user: admin
      password: admin

Security badge

OpenProject now provides a release indicator (security badge) that will inform administrators of an OpenProject installation on whether new releases or security updates are available for your platform.

If enabled, this option will display a badge with your installation status at Administration > Information right next to the release version, and on the home screen. It is only displayed to administrators.

The badge will match your current OpenProject version against the official OpenProject release database to alert you of any updates or known vulnerabilities. To ensure the newest available update can be returned, the check will include your installation type, current version, database type, enterprise status and an anonymous unique ID of the instance. To localize the badge, the user's locale is sent. No personal information of your installation or any user within is transmitted, processed, or stored.

To disable rendering the badge, uncheck the setting at Administration > System settings > General or pass the configuration flag security_badge_displayed: false .

Cache options:

• rails_cache_store: memcache for memcached or memory_store (default: file_store)
• cache_memcache_server: The memcache server host and IP (default: 127.0.0.1:11211)
• cache_expires_in: Expiration time for memcache entries (default: 0, no expiry)
• cache_namespace: Namespace for cache keys, useful when multiple applications use a single memcache server (default: none)

Asset options:

• rails_asset_host: A custom host to use to serve static assets such as javascript, CSS, images, etc. (default: nil)

Onboarding variables:

• onboarding_video_url: An URL for the video displayed on the onboarding modal. This is only shown when the user logs in for the first time.

Enterprise Limits

If using an Enterprise token there are certain limits that apply. You can configure how these limits are enforced.

fail_fast

default: false

If you set fail_fast to true, new users cannot be invited or registered if the user limit has been reached. If it is false then you can still invite and register new users but their activation will fail until the user limit has been increased (or the number of active users decreased).

Configured in the configuration.yml like this:

enterprise:
  fail_fast: true

Or through the environment like this:

OPENPROJECT_ENTERPRISE_FAIL__FAST=true

Backup enabled

default: true

If enabled, admins (or users with the necessary permission) can download backups of the OpenProject installation via OpenProject's web interface or via the API.

There are further configurations you can use to adjust your backups.

backup_enabled: true # enable/disable backups feature
backup_daily_limit: 3 # number of times backups can be requested per day across all users
backup_initial_waiting_period: 24.hours # time after which new backup token is usable
backup_include_attachments: true # include/exclude attachments besides db dump
backup_attachment_size_max_sum_mb: 1024 # if all attachments together are larger than this, they will not be included

Per default the maximum overall size of all attachments must not exceed 1GB for them to be included in the backup. If they are larger only the database dump will be included.

As usual this can be override via the environment, for example like this:

OPENPROJECT_BACKUP__ENABLED=true
OPENPROJECT_BACKUP__INCLUDE__ATTACHMENTS=true
OPENPROJECT_BACKUP__ATTACHMENT__SIZE__MAX__SUM__MB=1024

Show community links

If you would like to hide the homescreen links to the OpenProject community, you can do this with the following configuration:

OPENPROJECT_SHOW__COMMUNITY__LINKS=false

Web

Configuration of the main ruby web server (currently puma). Sensible defaults are provided.

web:
  workers: 2 # number of server processes
  timeout: 60 # seconds before a request times out
  wait_timeout: 10 # seconds before a request waiting to be served times out
  min_threads: 4
  max_threads: 16

Note: Timeouts only are supported when using at least 2 workers.

As usual these values can be overriden via the environment.

OPENPROJECT_WEB_WORKERs=2
OPENPROJECT_WEB_TIMEOUT=60 # overriden by: RACK_TIMEOUT_SERVICE_TIMEOUT
OPENPROJECT_WEB_WAIT__TIMEOUT=10 # overriden by: RACK_TIMEOUT_WAIT_TIMEOUT
OPENPROJECT_WEB_MIN__THREADS=4 # overriden by: RAILS_MIN_THREADS
OPENPROJECT_WEB_MAX__THREADS=16 # overriden by: RAILS_MAX_THREADS

statsd

default: { host: nil, port: 8125 }

OpenProject can push metrics to statsd. Currently these are simply the metrics for the puma server but this may include more in the future.

This is disabled by default unless a host configured.

statsd:
  host: 127.0.0.1
  port: 8125

Or via the environment:

OPENPROJECT_STATSD_HOST=127.0.0.1 # overriden by: STATSD_HOST
OPENPRJOECT_STATSD_PORT=8125 # overriden by: STATSD_PORT
