Docker zainstalować Tomcat

Sposób konstruując Dockerfile

Tworzenie Dockerfile

Najpierw utwórz Tomcat katalogu, używany do przechowywania kopii związanych rzeczy.

w3big@w3big:~$ mkdir -p ~/tomcat/webapps ~/tomcat/logs ~/tomcat/conf

katalog webapps zostaną odwzorowane w katalogu aplikacji konfiguracji kontenera Tomcat

Katalog dzienniki zostaną odwzorowane na katalogu dziennika kontenera Tomcat

profil katalogu conf zostaną odwzorowane na profilu tomcat pojemniku

Wprowadź tomcat utworzonego katalogu, tworzyć Dockerfile

Tworzenie lustro przez Dockerfile, zastąpić go własnym nazwiskiem

w3big@w3big:~/tomcat$ docker build -t tomcat .

Po utworzeniu, możemy znaleźć właśnie utworzony w lokalnej liście odbicie lustrzane

w3big@w3big:~/tomcat$ docker images|grep tomcat
tomcat              latest              70f819d3d2d9        7 days ago          335.8 MB

Tutaj możemy wyciągnąć oficjalnych serwerów

w3big@w3big:~/tomcat$ docker pull tomcat

Poczekaj, aż pobieranie zostanie ukończone, możemy znaleźć repozytorium tomcat odzwierciedlenie w lokalnej listy lustra.

Mirroring użyciu tomcat

uruchom kontenerów

w3big@w3big:~/tomcat$ docker run --name tomcat -p 8080:8080 -v $PWD/test:/usr/local/tomcat/webapps/test -d tomcat  
acb33fcb4beb8d7f1ebace6f50f5fc204b1dbe9d524881267aa715c61cf75320

Polecenie Opis:

-p 8080: 8080: 8080 zostaną odwzorowane do portu kontenerowego portu hosta 8080

-v $ PWD / test: / usr / local / tomcat / webapps / test: host testy w bieżącym katalogu jest zamontowana do pojemnika / test

Sprawdź pojemnik zaczyna okoliczności

w3big@w3big:~/tomcat$ docker ps
