My docker version is

Docker version 18.06.1-ce, build e68fc7a

My docker compose version is

docker-compose version 1.23.1, build b02f1306

Running CoreOS version 1911.3.0

I ended up resolving this issue by modifying the nginx and letsencrypt portions of my docker-compose.yml file to be as follows.

 nginx: 
    image: jwilder/nginx-proxy
    container_name: nginx
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro
      - /apps/docker-articles/nginx/vhost.d:/etc/nginx/vhost.d
      - /apps/docker-articles/nginx/certs:/etc/nginx/certs:ro
      - /apps/docker-articles/nginx/html:/usr/share/nginx/html
    restart: always
    ports:
      - "80:80"
      - "443:443"
    labels:
      - "NGINX_PROXY_CONTAINER=true"
    networks:
      - pleroma

  letsencrypt:
    image: jrcs/letsencrypt-nginx-proxy-companion:v1.5
    container_name: letsencrypt
    environment:
      - NGINX_PROXY_CONTAINER=true
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /apps/docker-articles/nginx/vhost.d:/etc/nginx/vhost.d
      - /apps/docker/articles/nginx/certs:/etc/nginx/certs:rw
      - /apps/docker-articles/nginx/html:/usr/share/nginx/html

It seems "volumes_from" is deprecated in docker-compose v3. As well as I had forgotted quotes around my label and needed to set my environment within letsencrypt.
