Docker EDEX

Project home: https://github.com/Unidata/edex-docker

---

EDEX can be run inside a docker container, which allows you to process data into an AWIPS system without requiring accessing and altering the machine's native CentOS installation and configuration.

The EDEX Docker Image is built on CentOS 7 and contains the latest Unidata AWIPS release (18.1.1).

This container is an ingest-only install, meaning there is no database or request server. This example requires a Database/Request server be configured for you to access remotely. See the Distributed EDEX document for more.

---

Download and Install Docker

Download and install Docker and Docker Compose:

• Docker for CentOS 7 Linux
• Docker for Mac
• Docker for Windows
• docker-compose (it should be bundled with Docker by default on Mac and Windows)

---

Run the EDEX Ingest Container

Clone the source repository:

git clone https://github.com/Unidata/edex-docker.git
cd edex-docker

Run the container with docker-compose:

docker-compose up -d edex-ingest

Confirm the container is running:

docker ps -a 

Enter the container:

docker exec -it edex-ingest bash    

Stop the container:

docker-compose stop

Delete the container (keep the image):

docker-compose rm -f

Run commands inside the container, such as:

docker exec edex-ingest edex

which should return something like:

[edex status]
 qpid        :: running :: pid 22474
 EDEXingest  :: running :: pid 21860 31513
 EDEXgrib    :: not running
 ldmadmin    :: running :: pid 22483

 edex (status|start|stop|setup|log|purge|qpid|users)

To update to the latest version and restart:

docker pull unidata/edex-ingest:latest
docker-compose stop
docker-compose up -d edex-ingest

---

Configuration and Customization

The file docker-compose.yml defines files to mount to the container and which ports to open:

edex-ingest:
  image: unidata/edex-ingest:latest
  container_name: edex-ingest
  volumes:
    - ./etc/ldmd.conf:/awips2/ldm/etc/ldmd.conf
    - ./etc/pqact.conf:/awips2/ldm/etc/pqact.conf
    - ./bin/setup.env:/awips2/edex/bin/setup.env
    - ./bin/runedex.sh:/awips2/edex/bin/runedex.sh
  ports:
    - "388:388"
  ulimits:
    nofile:
      soft: 1024
      hard: 1024

---

Mounted Files

etc/ldmd.conf

Defines which data feeds to receive. By default there is only one active request line (REQUEST IDS|DDPLUS ".*" idd.unidata.ucar.edu) to not overwhelm small EDEX containers ingesting large volumes of radar and gridded data files. Any updates to the file etc/ldmd.conf will be read the next time you restart the container.

etc/pqact.conf

Defines how products are processed and where they are written to on the filesystem. This is the full set of pattern actions used in Unidata AWIPS, and generally you do not need to edit this file. Instead control which data feeds are requested in ldmd.conf (above).

bin/setup.env

Defines the remote EDEX Database/Request server:

### EDEX localization related variables ###
export AW_SITE_IDENTIFIER=OAX
export EXT_ADDR=js-157-198.jetstream-cloud.org

Note

: EXT_ADDR must be set to an allowed EDEX Database/Request Server. In this example we are using a JetStream Cloud instance, which controls our edex-ingest access with IPtables, SSL certificates, and PostgreSQL pg_hba.conf rules. This server will not allow outside connections, you must change this to point to an appropriate server.

bin/runedex.sh

The default script run when the container is started, acts as a sort-of service manager for EDEX and the LDM (see ENTRYPOINT ["/awips2/edex/bin/runedex.sh"] in Dockerfile.edex), essentially:

/awips2/qpid/bin/qpid-wrapper &
/awips2/edex/bin/start.sh -noConsole ingest &
ldmadmin mkqueue
ldmadmin start
