I use docker-compose to run the ESPHome container which I use to flash ESPHome onto my ESP32 devices. To see how I do that, check the configs in this post.

Note: This guide does not get into detail how to install docker-compose though, but I’m sure you’ll find information about that.

[zsiti@docker ~]$ cat /home/zsiti/docker/docker-compose.yml
---
version: '3.1'
services:
  # https://hub.docker.com/r/esphome/esphome/tags
  # command for flashing: docker exec -it <container name: esphome> <command to run within the container: esphome> <configfile to load: esphome433.yaml> <specify esphome task: run/build/...>
  # command for flashing: docker exec -it esphome esphome esphome-esp32-ble.yaml run
  esphome:
    container_name: esphome
    image: esphome/esphome:1.14.3 # I use version locking to prevent unsuspected issues. I update the version tag before I wish to use the container for flashing
    volumes:
      - /home/zsiti/docker/esphome/:/config:rw
    #devices: # most of the time we'll be flashing over OTA (that's why we have port 6052), so the devices setting is not needed, only if it's the first flash of a new device
    #  - /dev/ttyUSB0:/dev/ttyUSB0 # the ESP device has to be mapped to the docker host (in my case it's a VM in ESXi), if it's not mapped, the /dev/ttyUSB0 device will not exist and the container will fail. If the ESP32 is not connected at the time, we need to comment out the devices section.
    environment:
      - ESPHOME_DASHBOARD_USE_PING=true
    ports:
      - 6052:6052
    restart: unless-stopped

As you can see, the ESPHome configs are stored in a persistent volume /home/zsiti/docker/esphome/

Running the command for flashing

docker exec -it esphome esphome esphome-esp32-ble.yaml run

Important note: The ESP32 devices I use have a “FLASH” or “BOOT” button close to the USB connector. You need to push that button for a few seconds just before the flashing process starts. If you don’t do that, the flashing will fail.
