DDEV

"DDEV is an open source tool for launching local [PHP, Python, NodeJS, etc] development environments in minutes. These environments can be extended, version controlled, and shared, so you can take advantage of a Docker workflow without Docker experience or bespoke configuration. Projects can be changed, powered down, or removed just as easily as they’re started."
GitHub | Docs

Terminology:

• host os (windows/macosx/linux)
• docker os (linux vm)
• containers (linux)

General flow of ddev tech stack
[ddev, on host os] -> [docker compose -> docker, in linux vm] -> [containers, linux, managed by docker]

Install DDEV and related tools

Follow the install steps for your OS
https://ddev.readthedocs.io/en/stable/
Before running any external shell or powershell scripts, read the install script for your OS.

Prerequisites:

Windows

• Recommended: use wsl2 and docker desktop, docker ce inside wsl (do your work mostly in windows)
• Alternative: use wsl2, docker ce inside wsl (do your work mostly in wsl/linux)
• Alternative: use virtual box, docker ce inside virtual box (do your work mostly in virtual box/linux)

Windows ides can access files in wsl2, but ide operations will be slower due to the different filesystems. Within wsl, for performance, do not reference files by /mnt/c/home/dev, instead use the linux file system, eg /home/dev or ~/

Install, update wsl
https://learn.microsoft.com/en-us/windows/wsl/install
https://learn.microsoft.com/en-us/windows/wsl/basic-commands

The ddev install uses chocolatey, a package manager for windows https://community.chocolatey.org/

Tip: Before installing ddev, you may want to change the default chocolatey tools install directory.
By default chocolatey installs itself to C:\ProgramData\chocolatey and installs tools to C:\tools\ (not great)
In an admin powershell, run:
[System.Environment]::SetEnvironmentVariable('ChocolateyToolsLocation','C:\ProgramData\ChocolateyTools', 'User')

Installing docker desktop may require a logout/reboot.
Ensure docker desktop is using wsl2, launch docker desktop
configure gear icon -> general -> use wsl2 based engine; resources -> wsl integration

You shouldn't need to directly access docker desktop when using ddev.

MacOSX

• Recommended: use colima, docker ce inside colima linux os (do your work mostly in macosx)
• Alternative: use docker desktop, docker ce inside docker desktop linux os (do your work mostly in macosx)
• Alternative: use virtual box, docker ce inside virtual box (do your work mostly in virtual box/linux)

You shouldn't need to directly use colima when using ddev.

Linux

• Recommended: docker ce
• Alternative: use docker desktop

DDEV Configuration

local config
a local config file can be used to merge with the main ddev config in .ddev/config.yaml

examples:

.ddev/config.local.yaml

hooks:

    post-start:

        - exec-host: echo -e "checking bootstrapping via \033[1;34mhttp://${DDEV_HOSTNAME}/ping\033[0m"

        - exec-host: curl http://your-repo.ddev.site/ping

        - exec-host: echo -e ""

ddev generated files
useful to see the docker config created by ddev.
do not edit as they will be re-generated on next start

.[dot folders] 

.ddev-docker-compose-base.yaml 

.ddev-docker-compose-full.yaml

mkcert
mkcert is a simple tool for making locally-trusted development certificates. eg allows local https without browser warnings
https://github.com/FiloSottile/mkcert

firefox
The non chrome browser
https://www.mozilla.org/en-US/firefox/new/
for ssl access to ddev sites, import the mkcert generated ca cert

• list CA location, > mkcert -CAROOT
• in firefox url, about:preferences#privacy
• filter, certificates
• View Certificates -> Authorities -> Import
• Select the rootCA.pem file
• find the imported cert in the list, find mkcert
• click Edit Trust, click enable for websites

ngrok
ngrok is a reverse proxy that creates a secure tunnel from a public endpoint to a locally running web service eg expose a local server behind a NAT or firewall to the internet

chocolatey
a package manager for windows

• opensource https://community.chocolatey.org/
• install https://chocolatey.org/install
• gui https://docs.chocolatey.org/en-us/chocolatey-gui/setup/installation

docker
container management docker ce is opensource, docker desktop is a subscription

mutagen
mutagen provides real-time file synchronization and flexible network forwarding for developers, extending the reach of local development tools to cloud-based containers and infrastructure. initial file sync can take a bit https://mutagen.io/

maxosx and windows:
Accessing lots of files between the host os and linux os can be slow due to the different filesystems. mutagen will perform a two-way sync between your os and the ddev managed docker container.

traefik
dddev routing ddev-router has been based on a forked, poorly-documented nginx reverse proxy. Versions after DDEV v1.21.3 add a new router based on the popular Traefik Proxy.

phpstorm
php, code ide
https://www.jetbrains.com/phpstorm/
a ddev plugin exists for phpstorm and webstorm, which can facilitate setting up xdebug, server, php config, stop/start ddev, etc

using ddev from the command line may be simpler and more consistent

General ddev, docker, and container tips

• manage ddev within the host windows/macosx os, and if needed manage docker ce via the cli within the linux vm (wsl for windows)
• one container per repo
  • changes inside container will not persist, as it is a container
  • any changes need to be made outside of container (code), or to ddev config (container services, config)
  • ddev configuration is stored in the relative directory .ddev/
  • to facilitate ddev updates, try to keep config changes to a minimal
• start project
  > ddev start
  initial file sync can take a bit
• stop project
  > ddev stop
• project details
  > ddev status
  > ddev describe
• list docker images
  inside linux host
  > docker ps
• show all projects
  > ddev list
• stop all containers
  > ddev poweroff
• restart a project
  often used after making .ddev config changes
  > ddev restart
• ddev images are debian based
  ssh into container to test or view config
  reminder, changes inside container will not persist
  > ddev ssh
• control processes, php-fpm, nginx, node
  ddev uses supervisorctl to control processes, as opposed to systemctl; inside linux host
  > supervisorctl restart php-fpm
  > supervisorctl restart nginx
  note, if a process dies or attempts to restart several times due to bad config, the container will stop.
• start npm run start command
  > ddev npm run start
• stop npm run start command
  > ddev npm run stop
• run phpstan
  > ddev composer phpstan
• view logs from host os
  > ddev logs
• view logs inside container
  > ddev ssh
  > vi [log]
  > tail -f [log]
• docker maintenance
  Sometimes, either due to bad ddev, docker, wsl, comila, or normal config/docker changes, you may end up with unused, disconnected images, containers.
  To clean up your system, and recover some storage; inside your linux host
  > docker system prune
• if ddev container won't start after config changes
  Fix or revert config changes, then
  > ddev restart
  "generally removes most things that need to be removed"
  > ddev poweroff
  > ddev rm -a
• if start multiple ddev containers at the same time, there may be port conflicts as they may try to grab the same 'random' or initial default port; either restart failed container, or add a pause between container starts
• check open ports in linux host
  > ss -l
