mbon-dashboard-server

Docker software stack for MBON server serving early-alert dashboards.

For more detailed documentation please see ./documentation/.

Examples

Below is a list of "product" instances that are built with this framework. Each "product" instance is built on a git branch in this repository, based off of the master branch.

Name	git branch	status	URL	Description
SEUS Monitoring Dash	client-seus	✔️ up	http://seus-dashboard.marine.usf.edu:3000	Cram in tons of data from MBON, NERRS, & GR NMS.
FGB NMS Sentinel Sites Dash	client-fgb	✔️ up	http://fgbnms-dashboard.marine.usf.edu:3000	Monitoring a ring of sites around the Flower Garden Banks National Marine Sanctuary where anomalously high values of chlorophyll-a concentration, for example, can be detected from satellite imagery before reaching the reefs.
FK NMS	client-fk	✔️ up	http://fknms-dashboard.marine.usf.edu:3000	Monitoring of satellite, bouy, & river discharge data around the Florida Keys National Marine Sanctuary.
FWRI SCTLD Dashboard	client-fwc	❌ project ended	http://fwc-dashboard.marine.usf.edu:3000	Monitoring the spread of stony coral tissue loss disease in the Florida Keys.

Repository "framework" & "product" organization

Herein we use the terms dashboard "framework" for something that people can use to build their own "products". An example product: "A dashboard so show fish population correlated with nutrient data and satellite imagery". Versus the framework: "The stack that someone could install, configure, and populate the DB to build the aforementioned product."

The "master" branch of the repository is the framework used to build products. This framework contains the common core of software configuration and setup for any product build.

The client-* branches (eg client-fgbnms, client-fk_water_quality, client-fknms, client-fwc) are products ready to be cloned built with minimal configuration.

For details on how to work within this organizational setup see the basic-workflow section below.

Directory Structure Overview

docker-compose.yml handles most configuration. The subdirectories (eg erddap, nginx, etc) contain container-specific files.

Setup

General Setup Notes

In general you will configure your stack by:

1. Modifying docker-compose.yml and container-specific configuration files inside of ./erddap/, ./grafana/, etc. Directions for this is included within a README.md file inside of each directory. Changes made to these files should be version controlled using git.
2. Setting up docker volumes so that data can persist when containers are recreated. Volumes are generally too large for git, so you should manage backups of these directories. A strategy for this is not included.
3. Setting passwords & configuration in .env. This file should not be added to git for security reasons. A backup strategy for this file is not included.

It is suggested that you configure each container one-at-a-time. To do this simply comment out the relevant sections of docker-compose.yml.

Setup Checklist

1. install docker & docker & the docker compose plugin
2. add permissions to run docker for current user
   1. sudo usermod -aG docker ${USER}
3. copy code from github to your machine
   1. git clone https://github.com/marinebon/mbon-dashboard-server.git -b client-fknms
      • NOTE: be sure to choose the right branch name (client-fknms, client-fgbns, etc)
   2. cd mbon-dashboard-server
   3. git submodule update --init --recursive --remote
4. Adjust settings. Products built on the mbon-dashboard-server base framework (like the FKNMS dashboard on the client-fknms branch) will already have configuration for these set up. Please take the REQUIRED steps below and use the OPTIONAL configuration options to further customize your usage as needed.
   1. REQUIRED set passwords in the environment .env file.
      • see the documentation/example_env_file for an example.
   2. REQUIRED: create data dir for PostgreSQL - see ./postgres/README.md
   3. OPTIONAL: connect ERDDAP to your data - see ./erddap/README.md
5. run initialization containers: docker compose up airflow-init
   • you will get a permissions error, so now you can chmod all the files that were created and run it again:
     • chmod -R 777 airflow/ influxdb/ grafana/ postgres/ && docker compose up airflow-init
     • that should run without error and exit
6. start everything up: docker compose up --build -d
7. REQUIRED: toggle "on" airflow processing DAGs - see issue #12
8. test it out (assuming your hostname is "localhost")
   1. http://localhost/ should show "welcome to nginx"
   2. http://localhost:8080/ should show a 404 from tomcat
   3. http://localhost:8080/erddap should show ERDDAP's page
   4. http://localhost:8086/health should show status report from InfluxDB
   5. http://localhost:3000/login should show grafana login
   6. http://localhost:5000 should show a data submission form from mbon_data_uploader
   7. http://localhost:8888 should show airflow login & admin dashboard after logging in
9. steps for after things are running 4. OPTIONAL: load data into InfluxDB - see ./influxdb/README.md 5. OPTIONAL: modify grafana dashboards - see ./grafana/README.md

debugging on the grafana interface

• 502: bad gateway error: this means that grafana can't connect to the timeseries database (influxDB).
  • check {URL}:8086/health to ensure InfluxDB okay
  • check connection urls in the config, firewalls, etc
  • check airflow jobs to ensure ingest is working.

Basic Workflow

The workflow here is to do any non-site-specific work on the master branch. Each client installation then has a client-* branch coming off of the master branch. To update a client branch to use the latest master git rebase is used.

Editing master

1. modify docker-compose.yml or files within container folders
2. docker-compose up --build -d to update what's running
3. git pull then git commit your changes
   • do not commit your .env or hostname changes to erddap/setup.xml

Update client branch with changes from master

3. git branch to be see if you are on the right branch
4. git branch client-*-backup-1 to create new backup branch
5. git fetch so git knows about remote repo changes
6. git rebase origin/master to prepend changes from master
7. resolve any merge issues
8. git push --force-with-lease origin client-*
   • !!! be careful with force pushing; it deletes history

requirements

• docker-compose ~> 1.28.5. Not sure exactly the min version but 1.21.2 was tested and does not work.
• ERDDAP generally requires > 8GB memory and more is better.
