-===== Docker and OpenSimulator =====
+====== Docker basics ======
+===== Installation =====
+Read the docs
+===== Web interface =====
+use "portainer" [[https://github.com/portainer/portainer|Github repo]]
+===== Remote API =====
+use "sherpa" [[https://github.com/djenriquez/sherpa|Github repo]]
+====== Websites ======
+===== Nginx + php-fpm =====
+[[http://geekyplatypus.com/dockerise-your-php-application-with-nginx-and-php7-fpm/|Source]]
+==== Create files ====
+  - Create a folder that will contain the config files and go inside. (The containers names will take the name of the folder)
+  - Create a folder named "www" (that will be mounted in /srv/www (equivalent of /var/www))
+  - Create a folder ./www/first_website and put your php code inside
+  - Create a folder ./www/second_website and put your php code inside
+  - Create a folder named "conf.d" (that will be mounted in /etc/nginx/conf.d)
+  - Create the following files :
+=== docker-compose.yml ===
+<sxh yml>
+nginx:
+    image: nginx:latest
+    ports:
+        - "8080:80"
+    volumes:
+        - ./www:/srv/www
+        - ./conf.d:/etc/nginx/conf.d
+    links:
+        - php
+php:
+    image: php:7-fpm
+    volumes:
+        - ./www:/srv/www
+</sxh>
+=== ./conf.d/site.conf ===
+<sxh bash>
+server {
+    index index.php index.html;
+    server_name php-docker.local;
+    error_log  /var/log/nginx/error.log;
+    access_log /var/log/nginx/access.log;
+    root /srv/www/first_website;
+    location ~ \.php$ {
+        try_files $uri =404;
+        fastcgi_split_path_info ^(.+\.php)(/.+)$;
+        fastcgi_pass php:9000;
+        fastcgi_index index.php;
+        include fastcgi_params;
+        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
+        fastcgi_param PATH_INFO $fastcgi_path_info;
+    }
+}
+</sxh>
+=== ./conf.d/site2.conf ===
+<sxh bash>
+server {
+    index index.php index.html;
+    server_name php-docker2.local;
+    error_log  /var/log/nginx/error.log;
+    access_log /var/log/nginx/access.log;
+    root /srv/www/second_website;
+    location ~ \.php$ {
+        try_files $uri =404;
+        fastcgi_split_path_info ^(.+\.php)(/.+)$;
+        fastcgi_pass php:9000;
+        fastcgi_index index.php;
+        include fastcgi_params;
+        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
+        fastcgi_param PATH_INFO $fastcgi_path_info;
+    }
+}
+</sxh>
+==== Run the containers ====
+<sxh bash>docker-compose up</sxh>
+===== Mysql =====
+<sxh bash>
+  docker run \
+   --name="mysql-dck" \
+   -v "/path/to/my.cnf":"/etc/my.cnf" \
+   -e MYSQL_ROOT_PASSWORD=mypassword \
+   -e MYSQL_ROOT_HOST=172.17.0.1 \
+   -d \
+    mysql/mysql-server:5.6
+</sxh>
+Note: i was not able to use root credentials as /root/.my.cnf
+==== Script to write to mysql ====
+=== First solution ===
+add this line to the previous command :
+<sxh bash>-v /tmp/mysql-temp:/tmp \</sxh>
+run this command :
+<sxh bash>docker exec mysql-dck /bin/sh -c 'mysql -u root -pmypassword < /tmp/mysql-temp/test-create.sql'</sxh>
+content of the file "test-create.sql" :
+<sxh sql>
+CREATE DATABASE IF NOT EXISTS `mybase` DEFAULT CHARACTER SET utf8;
+GRANT ALL PRIVILEGES ON `mybase`.* TO 'foo'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION;
+FLUSH PRIVILEGES;
+</sxh>
+=== Second solution ===
+run :
+<sxh bash>
+docker exec mysql-dck /bin/sh -c 'mysql -u root -pmypassword -e "CREATE DATABASE IF NOT EXISTS `mybase` DEFAULT CHARACTER SET utf8"'
+docker exec mysql-dck /bin/sh -c 'mysql -u root -pmypassword -e "GRANT ALL PRIVILEGES ON `mybase`.* TO \'foo\'@\'localhost\' IDENTIFIED BY \'password\' WITH GRANT OPTION;"'
+docker exec mysql-dck /bin/sh -c 'mysql -u root -pmypassword -e "FLUSH PRIVILEGES;"'
