For at installere images\/docker containers fra hub.docker.com<\/a>. kan du bruge search funktionen i docker. Her s\u00f8ger jeg efter webserver nginx containers. der er mange muligheder her.<\/p>\n

Du kan l\u00e6se om hvor du installere nginx her<\/a><\/p>\n

Du kan se hele listen p\u00e5 docker hub.<\/a><\/p>\n

For at eksempelvis installere nginx webserver fra docker hub skal du skrive.<\/p>\n

$ sudo docker run -itd --name nginxwebserver nginx \/bin\/bash\n$<\/pre>\n
Ingen output dejligt. S\u00e5 k\u00f8re containeren m\u00e5 vi h\u00e5be ?. Der er heldigvis mulig for at checke dette. med ps kommandoen.<\/p>\n
$ sudo docker ps\nCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES\nbab1387d71d7 nginx \"\/bin\/bash\" 6 minutes ago Up 6 minutes 80\/tcp nginxwebserver<\/pre>\n
Den er noget som k\u00f8re. hvordan ser jeg s\u00e5 ip adressen s\u00e5 jeg kan tilg\u00e5r webserveren nginx.<\/p>\n
$ sudo docker attach bab1387d71d7<\/pre>\n
For at f\u00e5 ip adressen p\u00e5 vores nginx container kan vi installere ifconfig.<\/p>\n
root@bab1387d71d7:\/# apt update\nroot@bab1387d71d7:\/# apt install net-tools\nroot@bab1387d71d7:\/# ifconfig\neth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500\ninet 172.17.0.2 netmask 255.255.0.0 broadcast 172.17.255.255\nether 02:42:ac:11:00:02 txqueuelen 0 (Ethernet)\nRX packets 5954 bytes 8975041 (8.5 MiB)\nRX errors 0 dropped 0 overruns 0 frame 0\nTX packets 3004 bytes 201306 (196.5 KiB)\nTX errors 0 dropped 0 overruns 0 carrier 0 collisions 0<\/pre>\n
S\u00e5 vi kan nu \u00e5bne en browser og se p\u00e5 ip adressen 172.17.0.2<\/p>\n
Yes det virker…<\/p>\n
\"\"<\/p>\n
Hvor ligger filerne s\u00e5 p\u00e5 webservren. Lad os se p\u00e5 det.<\/p>\n
root@bab1387d71d7:\/# cat \/etc\/nginx\/conf.d\/default.conf | grep -e root
root \/usr\/share\/nginx\/html;
root \/usr\/share\/nginx\/html;
# root html;
# deny access to .htaccess files, if Apache’s document root<\/p>\n
Vi kan se at root peger p\u00e5 \/usr\/share\/nginx\/html. S\u00e5 for at se filerne der skal vi p\u00e5 webserveren bruge cd kommandoen til det.<\/p>\n
root@bab1387d71d7:\/# cd \/usr\/share\/nginx\/html\nroot@bab1387d71d7:\/usr\/share\/nginx\/html# ls -l\ntotal 8\n-rw-r--r-- 1 root root 494 Jan 21 13:36 50x.html\n-rw-r--r-- 1 root root 612 Jan 21 13:36 index.html\n<\/pre>\n
Her kan du se listen af ubuntu images her.<\/p>\n
