docker-compose with multiple databases -


i'm trying figure out how implement docker using docker-compose.yml 2 databases imported sql dumps.

httpd:     container_name: webserver     build: ./webserver/     ports:         - 80:80     links:         - mysql         - mysql2     volumes_from:         - app  mysql:     container_name: sqlserver     image: mysql:latest     ports:         - 3306:3306     volumes:         - ./sqlserver:/docker-entrypoint-initdb.d     environment:         mysql_root_password: root         mysql_database: dbname1         mysql_user: dbuser         mysql_password: dbpass  mysql2:     extends: mysql     container_name: sqlserver2     environment:         mysql_root_password: root         mysql_database: dbname2         mysql_user: dbuser         mysql_password: dbpass  app:     container_name: webdata     image: php:latest     volumes:         - ../php:/var/www/html     command: "true"

the above returns following:

kronos:mybuild avanche$ ./run.sh  creating sqlserver creating webdata creating sqlserver2  error: mysql2  driver failed programming external connectivity on endpoint sqlserver2 (6cae3dfe7997d3787a8d59a95c1b5164f7431041c1394128c14e5ae8efe647a8): bind 0.0.0.0:3306 failed: port allocated traceback (most recent call last):   file "<string>", line 3, in <module>   file "compose/cli/main.py", line 63, in main attributeerror: 'projecterror' object has no attribute 'msg' docker-compose returned -1

basically, i'm trying whole stack setup in single docker compose file, create 2 databases , import respective sql dumps. have suggestions?

you're trying bind both database containers same port - 3306. impossible. need change port-mapping 1 of databases, example mysql keeps 3306:3306, , mysql2 should use 3307:3306.

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
