  Demyx looks very interesting, I am going to check it on weekend 😉
  Do you also consider of adding features like only html site container (I’m a fan of Hugo static) or php+mysql containers?

    Hi Arek,

    Yes I’m planning to implement support for html/php containers as soon as the commands for WordPress containers are stable. It might happen very soon! I did plan ahead and put the folder structure as a placeholder:

      So I tested a script and it is great, in my opinion one of the best for automation of docker and wordpress.
      But after a week, when I was trying to add another domain to the server I’m receiving message like this when I type any of demyx command:
      “error during connect: Get http://demyx_socket:2375/v1.40/containers/json: dial tcp: lookup demyx_socket on 127.0.0.11:53: no such host”
      Do you know what can cause this issue?

        Hi, I’ve updated the socket. In the future, you shouldn’t have these issues anymore. Can you run this on the host?

        demyx update –system

        If that doesn’t work, then feel free to ask for help in real time in my IRC channel: https://webchat.freenode.net/?channel=#demyx

  Hi,

  saw your post in the roots.io forum and looked through your code in github.
  Very nice, good work. Really like your design of your commands and the aspect of bundling tasks.
  I’m a big fan of automation scripts and played intensively with ansible for provisioning for quite a while.

  Because I looking for something like demyx, I wonder how you manage your developments and realize your deployment strategy. Are you doing your dev work and customizations via code-server directly on the server or do you make your work locally and push/sync it via git oder sftp?
  Lookin forward to hear from you.

    Hi aarkiin,

    Thank you for the compliments! I try to be as neat as I can when coding and commenting 😊. I do everything in code-server and remotely too! I haven’t dev locally on my laptop for a long time now. As for deployment, I wrote my own bash script that chains commands.

    #!/bin/bash

    cd /demyx/web/app/themes/demyx

    # Disable module.hot.accept()
    sed -i "s|module.hot.accept|//module.hot.accept|g" /demyx/web/app/themes/demyx/resources/assets/scripts/main.js

    if [[ "$1" = push ]]; then
    git push
    else
    yarn build:production

    # Exit if build fails
    if [[ "$?" != 0 ]]; then
    echo '############################'
    echo '# #'
    echo '# BUILD FAILED! #'
    echo '# #'
    echo '############################'
    exit 1
    fi

    composer install --no-dev
    git add .
    git commit -m "$1"
    git push
    composer install
    fi

    # Enable module.hot.accept()
sed -i "s|//module.hot.accept|module.hot.accept|g" /demyx/web/app/themes/demyx/resources/assets/scripts/main.js

    The script is chmoded and then executed via ~/deploy. If I don’t have to compile any css/js then I just commit that single file then ~/deploy push, else, it would compile. Here’s my .gitignore:

      Hi,
      Been learning Docker for the past week and what got me into it in the first place was the “dev/prod parity”, which leads me to my question: how do I setup demyx for local development?
      I’m really new to Docker so might I also ask if there is a philosophy behind why you would do everything remotely instead? Hoping you could clarify these things for me.

        Hi Abe,

        Demyx at the moment doesn’t support non SSL setup but that will have to change. The philosophy behind Demyx being SSL first is because I’ve been working remotely for years now on my dev servers. So it made sense to me that SSL has to be priority when working remotely.

        Demyx is almost a year old, I started this project with zero knowledge of how Docker worked, so I just kept learning and learning. Once you know how things are structured, you can easily modify Demyx by making custom Dockerfile or modifying the docker-compose.yml. If you’re adventurous enough, you can fork my repo and change the bash scripts.

        I hope this clarifies things for you. If not, feel free to reach out to me in the other channels. IRC is probably the effective and fastest way to communicate directly with me.

  Intesting project. Does it mean demyx is only suited for wordpress?
  can’t be used for other PHP app that’s not wordpress?

    Hey thanks for checking my project. At the moment, it’s focused on WordPress for now but there are placeholders I’ve added for HTML and PHP sites. Sorry I’ve missed the opportunity to say hi to you in the #demyx channel; I’m usually online after 7am PST.

  Is it possible to setup other dockers with your script?
  I’m hoping to install Bitwarden using your script. Is it possible? And what would you suggest be the best way to build such a docker setup with demyx?

    Yes of course it’s possible. In one of my servers, I have other Docker images running alongside the demyx stack. Some non-demyx containers running are Rocket Chat, The Lounge, Nextcloud, etc.

    All you would need is to use the same demyx network in your docker-compose.yml and the right Traefik labels. Here’s an example of my The Lounge docker-compose.yml:

    
version: "2.4"
services:
thelounge:
container_name: thelounge
image: demyx/thelounge
cpus: .5
mem_limit: 512m
restart: unless-stopped
volumes:
- thelounge:/var/opt/thelounge
labels:
- "traefik.enable=true"
- "traefik.http.routers.thelounge-http.rule=Host(`domain.tld`)"
- "traefik.http.routers.thelounge-http.entrypoints=http"
- "traefik.http.routers.thelounge-http.middlewares=thelounge-redirect"
- "traefik.http.routers.thelounge-https.rule=Host(`domain.tld`)"
- "traefik.http.routers.thelounge-https.entrypoints=https"
- "traefik.http.routers.thelounge-https.tls.certresolver=demyx"
- "traefik.http.middlewares.thelounge-redirect.redirectscheme.scheme=https"
networks:
- demyx
volumes:
thelounge:
name: thelounge
networks:
demyx:
name: demyx
