Service for RapidPro/TextIt which does the heavy lifting of running flow starts, campaigns etc. It interacts directly with the database and sends and receives messages with Courier for handling via Redis.
As a Go application, it compiles to a binary and that binary along with the config file is all you need to run it on your server. You can find bundles for each platform in the releases directory. We recommend running it behind a reverse proxy such as nginx or Elastic Load Balancer that provides HTTPs encryption.
The service uses a tiered configuration system, each option takes precendence over the ones above it:
- The configuration file
- Environment variables starting with
MAILROOM_ - Command line parameters
We recommend running it with no changes to the configuration and no parameters, using only
environment variables to configure it. You can use % mailroom --help to see a list of the
environment variables and parameters and for more details on each option.
For use with RapidPro/TextIt, you will need to configure these settings:
MAILROOM_ADDRESS: the address to bind our web server to (default "localhost")MAILROOM_DOMAIN: the domain that mailroom is listening onMAILROOM_AUTH_TOKEN: the token clients will need to authenticate web requests (should match setting in RapidPro)MAILROOM_ATTACHMENT_DOMAIN: the domain that will be used for relative attachments in flowsMAILROOM_DB: URL describing how to connect to the RapidPro database (default "postgres://temba:temba@localhost/temba?sslmode=disable")MAILROOM_READONLY_DB: URL for an additional database connection for read-only operations (optional)MAILROOM_REDIS: URL describing how to connect to Redis (default "redis://localhost:6379/15")MAILROOM_SMTP_SERVER: the smtp configuration for sending emails ex: smtp://user%40password@server:port/?from=foo%40gmail.comMAILROOM_FCM_KEY: the key for Firebase Cloud Messaging used to sync Android channelsMAILROOM_ELASTIC: URL describing how to connect to ElasticSearch (default "http://localhost:9200")MAILROOM_ELASTIC_USERNAME: ElasticSearch username for Basic AuthMAILROOM_ELASTIC_PASSWORD: ElasticSearch password for Basic Auth
For writing of message attachments, you need an S3 compatible service which you configure with:
MAILROOM_AWS_ACCESS_KEY_ID: the AWS access key id used to authenticate to AWSMAILROOM_AWS_SECRET_ACCESS_KEYthe AWS secret access key used to authenticate to AWSMAILROOM_S3_REGION: the region for your S3 bucket (ex:eu-west-1)MAILROOM_S3_ATTACHMENTS_BUCKET: the name of your S3 bucket (ex:mailroom-attachments)MAILROOM_S3_ATTACHMENTS_PREFIX: the prefix to use for filenames of attachments added to your bucket (ex:attachments)
You can use S3 storage for sessions and logs as well with:
MAILROOM_SESSION_STORAGE: where session output is stored which must bedb(default) ors3MAILROOM_S3_SESSIONS_BUCKET: The name of your S3 bucket (ex:mailroom-sessions)MAILROOM_S3_LOGS_BUCKET: The name of your S3 bucket (ex:mailroom-logs)
Flow engine configuration:
MAILROOM_MAX_STEPS_PER_SPRINT: the maximum number of steps allowed in a single engine sprintMAILROOM_MAX_RESUMES_PER_SESSION: the maximum number of resumes allowed in an engine sessionMAILROOM_MAX_VALUE_LENGTH: the maximum length in characters of contact field and run result values
Recommended settings for error and performance monitoring:
MAILROOM_LIBRATO_USERNAME: The username to use for logging of events to LibratoMAILROOM_LIBRATO_TOKEN: The token to use for logging of events to LibratoMAILROOM_SENTRY_DSN: The DSN to use when logging errors to SentryMAILROOM_LOG_LEVEL: the logging level mailroom should use (default "error", use "debug" for more)
Once you've checked out the code, you can build the service with:
go build github.com/rapidpro/mailroom/cmd/mailroom
This will create a new executable in $GOPATH/bin called mailroom.
To run the tests you need to create the test database:
$ createdb mailroom_test
$ createuser -P -E -s mailroom_test (set no password)
To run all of the tests:
go test -p=1 ./...
