- bound la carte limite pour ne pas voir la zone grise
- quelles infos on mets dans les infowindow
	- adresse en haut (surtout pour les markers avec plusieurs evenements)
- filtres: au dessus de la carte
- zoom : on reste avec le fonctionnement par defaut
	- est-ce qu'on peut changer la phrase "ctrl + scroll" pour un truc en francais ?

## questions

- ? will healthcheck continue after success, every 1 secondes ?
- ? why http to https redirection doesn't works ?

	###### Docker basics
	- the container posess its own filesystem
	- we need to copy the files it uses inside this filesystem
	- we can do that with COPY

	###### build and run a docker image
	- `sudo docker build --tag <name> .`
	- `sudo docker run <name>`
	- `sudo docker images` to list docker images
	- `sudo docker image rm <number>`
	- `sudo docker ps` to list docker processes
	- `sudo docker ps rm <name>`

	###### execute a docker-compose file
	- `sudo docker-compose up`
	- or `sudo docker-compose -f ./path up` to specify a path

	###### docker pid 1
	- nginx by default will create some child process (a master and some workers), then it quits (doc ?)
	- when the first process of a docker container exit, the container exit (doc ?)
	- so we must tell nginx to not go background : "-g 'daemon off'"
	- [pid1 docker problem](https://blog.phusion.nl/2015/01/20/docker-and-the-pid-1-zombie-reaping-problem/)
	- [official nginx docker image](https://hub.docker.com/_/nginx/)
	- "If you add a custom CMD in the Dockerfile, be sure to include -g daemon off; in the CMD in order for nginx to stay in the foreground, so that Docker can track the process properly (otherwise your container will stop immediately after starting)!"
	- [SO discussion on "-g 'daemon off'"](https://stackoverflow.com/questions/18861300/how-to-run-nginx-within-a-docker-container-without-halting)
	- "When PID 1 exits, the container will exit" (where is says in the doc ?)
	- ["By design, containers started in detached mode exit when the root process used to run the container exits"](https://docs.docker.com/engine/reference/run/#detached--d)

	###### install and use docker and compose
	- [how to install docker engine](https://docs.docker.com/engine/install/ubuntu/)
	- [github releases](https://github.com/docker/compose/releases)
	- [install last version of compose manually](https://docs.docker.com/compose/install/compose-plugin/#install-the-plugin-manually)
	- [install manually SO discussion](https://stackoverflow.com/questions/57456212/error-version-in-docker-compose-yml-is-unsupported)
	- [correct release version name for download with a 'v'](https://stackoverflow.com/questions/58747879/docker-compose-usr-local-bin-docker-compose-line-1-not-command-not-found)
	- the version installed with apt is 1.17.1, way out of date

		###### remove old versions
		- `sudo apt remove docker docker-engine docker.io containerd runc`

		###### preparing directory
		- `sudo apt update`
		- `sudo apt install ca-certificates curl gnupg lsb-release`
		- `sudo mkdir -p /etc/apt/keyrings`
		- `curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg`
		- `echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null`

		###### installing docker engine
		- `sudo apt update`
		- `sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-plugin`

		###### check if installation worked
		- `sudo docker run hello-world`

		###### installing docker compose (checked version on github release, see above)
		- notice the 'v' below, before the version name (docker doc has it wong)
		- `sudo curl -L "https://github.com/docker/compose/releases/download/v2.10.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose`
		- `sudo chmod +x /usr/local/bin/docker-compose`

		###### run docker without sudo on linux (https://docs.docker.com/engine/install/linux-postinstall/)
		- `sudo groupadd docker`
		- `sudo usermod -aG docker $USER`
		- `newgrp docker`

	###### volumes vs bind mounts :
	- [docker doc: use volumes](https://docs.docker.com/storage/volumes/)
	- [docker doc: use bind mounts](https://docs.docker.com/storage/bind-mounts/)
	- [comparison volume vs bind mounts](https://devopscook.com/docker-volumes-vs-bind-mounts/)
	- [fundamentals use of volumes and bind mounts](https://medium.com/dlt-labs-publication/bind-mounts-volumes-in-docker-81523303cbb4)
	- [how volumes and bind mounts are really differents](https://serverfault.com/questions/996785/docker-volumes-vs-mount-binds-what-are-the-use-cases)
	- bind mounts are normal files anywhere on the computer, that docker container can access with absolut path and modify. They can also be modified without docker, since they are juste files
	- volumes are only modifiable by docker, they don't need an absolut path, and they are not dependent of host architecture

	###### use password in container :
	- [with env variables in compose](https://docs.docker.com/compose/environment-variables/)
	- [it's not safe to use arg to pass secret, since they are available through "docker history"](https://docs.docker.com/engine/reference/builder/#arg)
	- [better use docker build --secret tag](https://docs.docker.com/develop/develop-images/build_enhancements/#new-docker-build-secret-information)
	- [so discussion](https://stackoverflow.com/questions/22651647/docker-and-securing-passwords)
	- [engine ref secret](https://docs.docker.com/engine/reference/commandline/secret/)
	- [compose secret](https://docs.docker.com/compose/compose-file/compose-file-v3/#secrets)
	- [use secret with docker](https://www.rockyourcode.com/using-docker-secrets-with-docker-compose/)
	- [use secret with docker SO](https://stackoverflow.com/questions/42139605/how-do-you-manage-secret-values-with-docker-compose-v3-1)
	- [four ways to use secrets](https://blog.mikesir87.io/2017/05/using-docker-secrets-during-development/)
	- it seems that using "secrets" only improve security for a swarm, when you must share your secrets with others, but if not the case, .env is as much secure ?
	- to use secret in docker-compose, we need to use swarm, but it doesn't allow to use build, or up, so everything is different then and I don't have time to understand it fully

	- or : `ps -ax | grep nginx`
	- `sudo nginx -s quit` to stop it
	- `sudo docker system prune -af --volumes` -> `-a` also unused images, `-f` without prompt for confirmation
		- remove stopped containers
		- remove unused networks
		- remove unused images

	- `sudo docker stop $(sudo docker ps -q)` stop all runnings containers
