Using Redash `preview`
These are (at least initially) some rough notes on how to use the Redash preview image, including workarounds for any issues found.
Note that this is being written with the Redash 24.04.0-dev docker image in mind
Doing a fresh installation of Redash using the preview image is fairly simple.
Use the setup.sh script from here, and run it with the --preview option:
$ sudo ./setup.sh --preview
When that finishes, you need to add a few items to the environment file in /opt/redash/env to complete the configuration.
Without this, emails sent by Redash will be missing the server name in embedded links.
eg /something/ instead of https://your.server/something
Make sure to include the http:// or https:// text fragment at the start, otherwise that will be missing from the emails too
REDASH_HOST=http://your.server
For Redash to send email, it needs to know how to send email.
@justinclift uses an external service called SMTP2Go which has proven to be reliable, and not expensive. They have a free tier as well which is probably all most people would need.
You don't have to use SMTP2Go though, you just need to pick a place that supports standard SMTP protocol, preferably with TLS (for security purposes).
REDASH_MAIL_SERVER=mail.smtp2go.com
[email protected]
REDASH_MAIL_PORT=2525
REDASH_MAIL_USE_TLS=yes
REDASH_MAIL_USERNAME=an_smtp2go_username
REDASH_MAIL_PASSWORD=the_matching_smtp2go_password
Then apply those changes:
$ cd /opt/redash
$ docker compose up -d
