Confluence configuration ¶

Application configuration ¶

Helm chart version ¶

confluence_helm_chart_version sets the Helm chart version of Confluence instance.

confluence_helm_chart_version = "1.2.0"

Confluence version tag ¶

Confluence will be installed with the default version defined in its Helm chart. If you want to install a specific version of Bamboo, you can set the confluence_version_tag to the version you want to install.

For more information, see Confluence Version Tags.

confluence_version_tag = "<CONFLUENCE_VERSION_TAG>"

Number of Confluence application nodes ¶

The initial Confluence installation needs to be started with a single application node. After all the setup steps are finished, it is possible to update the confluence_replica_count with a number higher than 1 and run install.sh to update the application node count.

# Number of Confluence application nodes
# Note: For initial installation this value needs to be set to 1 and it can be changed only after Confluence is fully
# installed and configured.
confluence_replica_count = 1

Installation timeout ¶

confluence_installation_timeout defines the timeout (in minutes) for product helm chart installation. Different variables can influence how long it takes the application from installation to ready state. These can be dataset restoration, resource requirements, number of replicas and others.

confluence_installation_timeout = 10

License ¶

confluence_license takes the license key of Confluence product. Make sure that there is no new lines or spaces in license key.

confluence_license = "<LICENSE_KEY>"

Confluence instance resource configuration ¶

The following variables set number of CPU, amount of memory, maximum heap size and minimum heap size of Confluence instance. (Used default values as example.)

confluence_cpu                 = "2"
confluence_mem                 = "1Gi"
confluence_min_heap            = "256m"
confluence_max_heap            = "512m"

Synchrony instance resource configuration ¶

The following variables set number of CPU, amount of memory, maximum heap size, minimum heap size, and stack size of Synchrony instance. (Used default values as example.)

synchrony_cpu                 = "2"
synchrony_mem                 = "2.5Gi"
synchrony_min_heap            = "1g"
synchrony_max_heap            = "2g"
synchrony_stack_size          = "2048k"

Collaborative editing ¶

confluence_collaborative_editing_enabled enables Collaborative editing. (default: true)

confluence_collaborative_editing_enabled = true

RDS Configuration ¶

Database engine version ¶

confluence_db_major_engine_version sets the PostgeSQL engine version that will be used.

confluence_db_major_engine_version = "14" 

Database Instance Class ¶

confluence_db_instance_class sets the DB instance type that allocates the computational, network, and memory capacity required by the planned workload of the DB instance. For more information about available instance classes, see DB instance classes — Amazon Relational Database Service.

confluence_db_instance_class = "<INSTANCE_CLASS>"  # e.g. "db.t3.micro"

Database Allocated Storage ¶

confluence_db_allocated_storage sets the allocated storage for the database instance in GiB.

confluence_db_allocated_storage = 100 

You may want to adjust these values according to your needs. For more information, see Amazon RDS DB instance storage — Amazon Relational Database Service.

Database IOPS ¶

confluence_db_iops sets the requested number of I/O operations per second that the DB instance can support.

confluence_db_iops = 1000

You may want to adjust these values according to your needs. For more information, see Amazon RDS DB instance storage — Amazon Relational Database Service.

Database name ¶

confluence_db_name defines the name of database to be used for the Confluence in RDS instance.

If you restore the database, you need to provide the db name from the snapshot. If the snapshot does not have default db, then name set this variable to null.

confluence_db_name = "confluence"

Shared home configuration ¶

Shared home size ¶

confluence_shared_home_size sets the size of shared home storage in Gi. Default is 10Gi.

confluence_shared_home_size = "10Gi"

NFS server resource configuration ¶

NFS is used as shared home storage for Confluence. The deployment will create an NFS server within the cluster. The following variables set the initial cpu/memory request sizes including their limits for the NFS instance. (Default values used as example.)

# Confluence NFS instance resource configuration
confluence_nfs_requests_cpu    = "1"
confluence_nfs_requests_memory = "1Gi"
confluence_nfs_limits_cpu      = "2"
confluence_nfs_limits_memory   = "2Gi"

S3 for attachment storage ¶

Since Confluence 8.1 AWS S3 can be used for storing and managing attachment data.

confluence_s3_attachments_storage enables AWS S3 attachment storage, where Terraform will automatically create an S3 bucket, IAM role and policy. By default, this property is commented out.

confluence_s3_attachments_storage = true

Dataset restore configuration ¶

To restore the dataset into the newly created instance, configure all the parameters in this section.

Database Snapshot Identifier ¶

confluence_db_snapshot_id sets the identifier of the DB snapshot to restore from. If you do not specify a value, no AWS RDS snapshot will be used.

confluence_db_snapshot_id = "<SNAPSHOT_IDENTIFIER>"   # e.g. "my-snapshot"

Database Master Username ¶

confluence_db_master_username sets the username for the RDS master user. If you do not specify a value, username is "postgres".

confluence_db_master_username = "<DB_MASTER_USERNAME>"   # e.g. "postgres"

Database Master Password ¶

confluence_db_master_password sets the password for the RDS master user. If you do not specify a value, a random password will be generated.

confluence_db_master_password = "<DB_MASTER_PASSWORD>"   # default value is null

Build Number ¶

confluence_db_snapshot_build_number configures Confluence instance with the correct build number that stores in the snapshot. Without a matching build number, Confluence will not be able to start. List of build numbers.

confluence_db_snapshot_build_number = "<BUILD_NUMBER>" # e.g. "8703"

Shared home snapshot id ¶

To restore a shared home dataset, you can provide an EBS snapshot id that contains content of the shared home volume. This volume will then be mounted to the NFS server and used when the product is started.

confluence_shared_home_snapshot_id sets the id of shared home EBS snapshot. Make sure the snapshot is available in the region you are deploying to and follows all product requirements.

confluence_shared_home_snapshot_id = "<SHARED_HOME_EBS_SNAPSHOT_IDENTIFIER>"
