Yeah, did some more thinking and am now trying to “just” use docker image tagging for versions so I can use deployments more properly. Working on Laravel PHP FPM image in which I include the demo code now:
FROM php:7.4-fpm
WORKDIR /code
# https://learnk8s.io/blog/kubernetes-deploy-laravel-the-easy-way
# COPY . app to copy all laravel app files to this working directory
# Only use this option when this container is in a private repository
# Composer is added to https://github.com/smart48/smt-workspace
RUN apt-get update && apt-get install -y libmcrypt-dev zip unzip git \
libmagickwand-dev --no-install-recommends \
&& pecl install imagick \
&& docker-php-ext-enable imagick \
&& docker-php-ext-install pdo_mysql pcntl bcmath \
&& docker-php-ext-install opcache
# Configure non-root user.
ARG PUID=1000
ENV PUID ${PUID}
ARG PGID=1000
ENV PGID ${PGID}
RUN groupmod -o -g ${PGID} www-data && \
usermod -o -u ${PUID} -g www-data www-data
COPY ./laravel.ini /usr/local/etc/php/conf.d
COPY ./opcache.ini /usr/local/etc/php/conf.d
COPY ./xlaravel.pool.conf /usr/local/etc/php-fpm.d/
COPY laravel /code
# Install Composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
RUN composer install \
&& php artisan optimize \
&& php artisan route:cache
This builds works well locally (outside of Minikube running Docker for Mac) and when I enter the container I can see the code added. I tagged the image and pushed it to Docker Hub:
docker tag smart48/smt-laravel smart48/smt-laravel:1.2
and it is on Docker Hub here.
and locally I see this on my Mac’s container:
docker run --name smt-laravel -d smart48/smt-laravel:1.2
53e4d1fc52042b6923be79d4590f5babe29b82efcb2cf04cfba7b6e95dd4b062

However when I build Minikube with all the deployments the PHP deployment
