I have used Docker-compose a lot recently, but this time I found a container I really want to use but the docker hub’s image is not compatible with my arm/v6 raspberry pi.
Using it anyway results in
standard_init_linux.go:219: exec user process caused: exec format error
Strangely, copying the Dockerfile and building it with
build:
context: ./ttrss-docker/src/app
results in the app working well. But for some reason, I can’t use the dockerhub’s image.
In case it matters, the Dockerfile is this, and the Docker Hub image is this.
FROM alpine:3.12
EXPOSE 9000/tcp
RUN apk add --no-cache dcron php7 php7-fpm
php7-pdo php7-gd php7-pgsql php7-pdo_pgsql php7-mbstring
php7-intl php7-xml php7-curl php7-session
php7-dom php7-fileinfo php7-json
php7-pcntl php7-posix php7-zip php7-openssl
git postgresql-client sudo
ADD startup.sh /
ADD updater.sh /
ADD index.php /
ADD dcron.sh /
ADD backup.sh /etc/periodic/weekly/backup
RUN sed -i.bak 's/^listen = 127.0.0.1:9000/listen = 9000/' /etc/php7/php-fpm.d/www.conf
RUN sed -i.bak 's/(memory_limit =) 128M/1 256M/' /etc/php7/php.ini
RUN mkdir -p /var/www
CMD /startup.sh
Question: if I don’t use the Docker hubs image, can Watchtower update my container ?
If not, does anyone know what’s happening and how I can achieve a container that updates via Watchtower ?
Many thanks :)
