dockerコンテナ作った（Dockerfileから）

#イメージの作成

＊コンテナ起動時にapacheが自動起動しない・・・なぜだ

追記
CMD /usr/sbin/apachectl -D FOREGROUND
にすれば自動起動した

Dockerfileを準備

mkdir -p /usr/local/etc/docker_files/test/
vi /usr/local/etc/docker_files/test/Dockerfile

FROM ubuntu

RUN apt-get update
RUN apt-get -y upgrade
RUN apt-get install -y sudo
RUN sudo apt-get install -y vim
RUN sudo apt-get install -y curl
RUN sudo apt-get install -y tzdata
RUN sudo apt-get install -y php7.4

ADD ./home /home/
ADD ./php.ini /usr/local/etc/php/
ADD ./apache2 /usr/local/etc/
COPY ./startup.sh /usr/local/etc/
RUN chmod 744 /usr/local/etc/startup.sh

RUN ["sudo", "/bin/bash", "-c", "echo \"ServerName $HOSTNAME\" > /etc/apache2/conf-available/fqdn.conf"]
RUN a2enconf fqdn
#RUN apachectl start

EXPOSE 80
CMD ["/usr/local/etc/startup.sh"]
#ENV APACHE_RUN_USER www-data
#ENV APACHE_RUN_GROUP www-data
#ENV APACHE_PID_FILE /var/run/apache2.pid
#ENV APACHE_RUN_DIR /var/run/apache2
#ENV APACHE_LOG_DIR /var/log/apache2
#ENV APACHE_LOCK_DIR /var/lock/apache2
#CMD ["apachectl", "-D", "FOREGROUND"]
#RUN ["sudo", "/bin/bash", "-c", "/etc/init.d/apache2 start"]
#RUN ["sudo", "/bin/bash", "-c", "/usr/sbin/apachectl -D FOREGROUND"]

Dockerfileからイメージを作成

イメージあるかどうか確認

docker image ls
REPOSITORY   TAG       IMAGE ID       CREATED          SIZE

ビルド（イメージを作成）

docker build -t test /usr/local/etc/docker_files/test/

できたかどうか確認

docker image ls
REPOSITORY   TAG       IMAGE ID       CREATED          SIZE
php74test    latest    b5f7bfd05352   58 seconds ago   297MB
ubuntu       latest    f63181f19b2f   24 hours ago     72.9MB

##コンテナ作成

docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES

docker run --name container01 -it php74test:latest /bin/bash

Ctrl + P + Q でコンテナから出る

docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
a3270221bbd8   php74test:latest   "/bin/bash"   54 seconds ago   Up 53 seconds             container01

docker attach container01
