JDK/JRE

The Atlassian Confluence Linux installer will automatically configure a bundled JRE.

If you prefer Confluence standalone installation, then you have to manage JDK/JRE 8 (Supported Platforms) on this node. It can be done with java cookbook and appropricate attributes:

node.default['java']['jdk_version'] = "8"
include_recipe 'java'

Attributes

These attributes are under the node['confluence'] namespace.

Attribute	Description	Type	Default
checksum	SHA256 checksum for Confluence install	String	auto-detected by library method
home_path	home directory for Confluence user	String	/var/atlassian/application-data/confluence
install_path	location to install Confluence	String	/opt/atlassian/confluence
install_type	Confluence install type - "installer", "standalone"	String	installer
url	URL for Confluence install	String	auto-detected by library method
user	user running Confluence	String	confluence
version	Confluence version to install	String	6.1.2

Notice: If ['confluence']['install_type'] is set to installer, then the installer will try to upgrade your Confluence instance located in ['confluence']['install_path'] (if it exists) to the ['confluence']['version'].

If you want to avoid an unexpected upgrade, just set or override ['confluence']['version'] attribute value to that of your current confluence version.

Confluence Database Attributes

These attributes are under the node['confluence']['database'] namespace.

Attribute	Description	Type	Default
host	FQDN or IP of database server ("127.0.0.1" automatically installs ['database']['type'] server)	String	"127.0.0.1"
name	Confluence database name	String	confluence
password	Confluence database user password	String	changeit
port	Confluence database port	Fixnum	3306 for MySQL, 5432 for PostgreSQL
type	Confluence database type - "mysql", "postgresql", or "hsqldb"	String	mysql
user	Confluence database user	String	confluence

Confluence JVM Attributes

These attributes are under the node['confluence']['jvm'] namespace.

Attribute	Description	Type	Default
minimum_memory	JVM minimum memory	String	512m
maximum_memory	JVM maximum memory	String	768m
maximum_permgen	JVM maximum PermGen memory	String	256m
java_opts	additional JAVA_OPTS to be passed to Confluence JVM during startup	String	""
bundled_jre	prefer JRE bundled with linux installer	Boolean	true

Confluence Autotune Attributes

These attributes are under the node['confluence']['autotune'] namespace. Autotune automatically determines appropriate settings for certain attributes. This feature is inspired by the autotune recipe in the https://github.com/afklm/jira cookbook. This initial version only supports JVM min and max memory size tuning.

There are several tuning types that can be set:

• 'mixed' - Confluence and DB run on the same system
• 'dedicated' - Confluence has the system all to itself
• 'shared' - Confluence shares the system with the DB and other applications

Total available memory is auto discovered using Ohai but can be overridden by setting your own value in kB.

Attribute	Description	Type	Default
enabled	Whether or not to autotune settings.	Boolean	false
type	Type of tuning to apply. One of 'mixed', 'dedicated' and 'shared'.	String	mixed
total_memory	Total system memory to use for autotune calculations.	String	Ohai value

Confluence Tomcat Attributes

These attributes are under the node['confluence']['tomcat'] namespace.

Attribute	Description	Type	Default
port	Tomcat HTTP port	Fixnum	8090

Usage

Confluence Data Bag

For security purposes it is recommended to use data bag for storing secrets like passwords and database credentials.

You can override any attributes from the ['confluence'] namespace using the confluence/confluence data bag. It could be either encrypted or not encrypted by your choice.

Example:

{
  "id": "confluence",
  "confluence": {
    "database": {
      "type": "postgresql",
      "name": "confluence_db",
      "user": "confluence_user",
      "password": "confluence_db_password"
    }
  }
}

(Note - "confluence" nesting level is required!)

These credentials will be used for your Confluence installation instead of appropriate attribute values.

Data bag's and item's names are optional and can be changed by overriding attributes ['confluence']['data_bag_name'] and ['confluence']['data_bag_item']

Confluence Server Installation

The simplest method is via the default recipe, which uses node['confluence']['install_type'] to determine best method.

• Optionally (un)encrypted data bag or set attributes
  • knife data bag create confluence
  • knife data bag edit confluence confluence --secret-file=path/to/secret
• Add recipe[confluence] to your node's run list.

Custom Confluence Configurations

Using individual recipes, you can use this cookbook to configure Confluence to fit your environment.

• Optionally (un)encrypted data bag or set attributes
  • knife data bag create confluence
  • knife data bag edit confluence confluence --secret-file=path/to/secret
• Add individual recipes to your node's run list.
