This section describes how to get Tethys Platform up and running as a fresh installation for app development. If you are upgrading an existing installation the refer to the Upgrade to 3.0.0 docs. If you are deploying a production instance of Tethys Portal refer to the Production Installation docs. If you want to contribute to the Tethys Platform source code itself then refer to the Developer Installation docs.
Also, be sure that the system you are using meets the minimum System Requirements.
1. Install the
tethysplatform Conda Package¶
To install the
tethysplatform into a new conda environment then run the following commands:
conda create -n tethys -c tethysplatform -c conda-forge tethysplatform conda activate tethys
To install a development build of of
tethysplatform prepend the
tethys/label/dev channel to the list of conda channels:
conda create -n tethys -c tethys/label/dev -c tethysplatform -c conda-forge tethysplatform
Alternatively, to install from source refer to the Developer Installation docs.
2. Create a
Tethys requires a
settings.py file to configure the database and other local settings. To generate a new
settings.py with default values for your local installation run:
tethys gen settings
You can customize your
settings.py file when you generate it by passing in command line options. Refer to the gen <type> docs to see what options are available.
To see where the
settings.py file is saved on disk run the following command:
tethys list -s
If you want to edit the file manually and have a commandline editor, such as
vi installed then you can run:
vi $(tethys list -s)
3. Configure the Tethys Database¶
Tethys Platform requires a PostgreSQL database server. There are several options for setting up a DB server: local, docker, or dedicated. For development environments you can use Tethys to create a local server:
tethys db configure
The tethys db command (db <subcommand> [options]) will create a local database server in the directory specified by the
DIR setting in the
DATABASES section of the
settings.py file. If the value of
DIR is a relative path then the database server will be created relative to directory specified by the
TETHYS_HOME environment variable. By default
TETHYS_HOME is at ~/.tethys.
As an alternative to creating a local database server you can also configure a Docker DB server (see Using Docker). A local database server is only recommended for development environments. For production environments please refer to Production Installation.
4. Start the Development Server¶
Once you have a database successfully configured you can run the Tethys development server:
tethys manage start
This will start up a locally running web server. You can access the Tethys Portal by going to http://localhost:8000 in your browser.
You can customize the port that the server is running on by adding the
tethys manage start -p 8001
See manage <subcommand> [options] for more details.
