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
