I have a problem when I upload my API on the Azure service app, a ping on port 80 does not find it and returns an error.
If I manually launch my docker on the machine via SSH with --network=host, and I ping on port 80 it works.
It may be a bad configuration on my part on the Dockerfile, but I don't know what it is.
How can I fix this problem?
FROM ruby:2.4
RUN curl -sL https://deb.nodesource.com/setup_12.x | bash -
RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list && \
apt-get update && apt-get install -qq -y build-essential libpq-dev nodejs yarn
WORKDIR /api
COPY . .
RUN bundle install
CMD bundle exec thin -p 80 start
EXPOSE 80
In the Azure app service portal, under the settings -> configuration -> Application Settings , please check if you have added a property PORT.
If not, add 80.

I am trying to build a simple Apache/PHP server using the Amazon Linux 2 image. I have the following:
Dockerfile
FROM amazonlinux:2
RUN amazon-linux-extras install epel -y &&\
amazon-linux-extras install php7.4 -y &&\
yum update -y &&\
yum install httpd -y
COPY --chown=root:root docker/script/startup /startup
ENTRYPOINT /startup
startup
#!/usr/bin/env bash
mkdir -p /run/dbus # Added this based on other SO question
dbus-daemon --system # Added this based on other SO question
systemctl enable dbus # Added this based on other SO question
systemctl start dbus # Added this based on other SO question
systemctl status dbus # Added this based on other SO question
systemctl enable httpd
systemctl start httpd
systemctl status httpd
/bin/bash
docker-compose.yml
web:
build: .
container_name: "${APP_NAME}-app"
environment:
VIRTUAL_HOST: "${WEB_HOST}"
env_file:
- ./.env-local
working_dir: "/${APP_NAME}/app"
restart: "no"
privileged: true # Added this based on other SO question
volumes:
- "./app:/${APP_NAME}/app:ro"
- ./docker:/docker
- "./conf:/${APP_NAME}/conf:ro"
- "./vendor:/${APP_NAME}/vendor:ro"
- "./conf:/var/www/conf:ro"
- "./web:/var/www/html/"
depends_on:
- composer
I run this with the following command:
docker run -it web bash
And this is what it gives me:
Failed to get D-Bus connection: Operation not permitted
Failed to get D-Bus connection: Operation not permitted
Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service, pointing to /usr/lib/systemd/system/httpd.service.
Failed to get D-Bus connection: Operation not permitted
Failed to get D-Bus connection: Operation not permitted
I don't understand why I'm getting this or how to resolve?
Suggesting to avoid systemd service units in a docker image.
Instead use cronttab script with #boot directive/selector.
In addition dbus is centrally managed by kernel and not allowed at container level.
If Docker service is up then you probably have dbus active and running.
You can add capabilities to the root user running in the container. Read more here.
As last resort try to disable SELinux in your docker image.
I was running into the same issue trying to run systemctl from within the Amazon Linux 2 docker image
Dockerfile:
FROM amazonlinux:latest
# update and install httpd 2.4.53, php 7.4.28 with php extensions
RUN yum update -y; yum clean all
RUN yum install -y httpd amazon-linux-extras
RUN amazon-linux-extras enable php7.4
RUN yum clean metadata
RUN yum install -y php php-{pear,cli,cgi,common,curl,mbstring,gd,mysqlnd,gettext,bcmath,json,xml,fpm,intl,zip}
# update website files
WORKDIR /var/www/html
COPY phpinfo.php /var/www/html
RUN chown -R apache:apache /var/www
CMD ["/usr/sbin/httpd","-DFOREGROUND"]
EXPOSE 80
EXPOSE 443
$ docker build -t azl1
$ docker run -d -p 8080:80 --name azl1_web azl1
pointing a browser to the IP:8080/phpinfo.php brought up the normal phpinfo page as expected pointing to a successful php 7.4.28 installation.
Im fairly new to docker and so im trying to learn more about it using a laravel project, im following this tutorial:
https://www.digitalocean.com/community/tutorials/how-to-set-up-laravel-nginx-and-mysql-with-docker-compose
Ive adjusted the Dockerfile a bit from what the tutorial has but even the tutorial file causes the same result.
FROM php:7.3-fpm
# Copy composer.lock and composer.json
COPY composer.lock composer.json /var/www/
# Install dependencies
RUN curl -sL https://deb.nodesource.com/setup_10.x | bash - && \
apt-get update && apt-get install -y mysql-client \
RUN npm install -g npm
# Clear cache
RUN apt-get clean && rm -rf /var/lib/apt/lists/*
# Install extensions
RUN docker-php-ext-install pdo pdo_mysql
# Install composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
# Add user for laravel application
RUN groupadd -g 1000 www
RUN useradd -u 1000 -ms /bin/bash -g www www
# Copy existing application directory contents
COPY . /var/www
# Copy existing application directory permissions
COPY --chown=www:www . /var/www
# Change current user to www
USER www
# Set working directory
WORKDIR /var/www
# Expose port 9000 and start php-fpm server
EXPOSE 9000
CMD ["php-fpm"]
But i keep getting the following error when i run docker-compose up -d:
E: Package 'mysql-client' has no installation candidate
ERROR: Service 'app' failed to build: The command '/bin/sh -c curl -sL https://deb.nodesource.com/setup_10.x | bash - && apt-get update && apt-get install -y mysql-client nodejs build-essential vim git curl' returned a non-zero code: 100
Am i missing something?
I expected this to work since i am running apt-get update before installing mysql-client.
Thanks.
php:7.3-fpm now use Debian 10 (Buster) as its base image and Buster ships with MariaDB, so just replace mysql-client with mariadb-client should fix it.
If you still want to use the mysql client, it's called default-mysql-client now.
php:7.2-apache triggers the error as well, but I resolve it using php:7.2.18-apache
it worked for me: sudo apt-get update && apt-get install -y git curl libmcrypt-dev default-mysql-client
or alternatively apt-cache search mysql-server
find out your servers then sudo apt-get install default-mysql-server default-mysql-server-core mariadb-server-10.6 mariadb-server-core-10.6
in my case it was the above codes
I have created a Dockerfile in my file structure, built a docker repository, and tried to run it, but I keep getting the following error:
Error response from daemon: repository not found, does not exist, or no pull access.
I'm pretty new to docker, so what could possibly be wrong here?
Commands I run:
docker build -t repoName .
docker run -d -p 8080:80 repoName
My Dockerfile:
FROM nginx:1.10.3
RUN mkdir /app
WORKDIR /app
# Setup enviromnet
RUN apt-get update
RUN apt-get install -y curl tar
RUN curl -sL https://deb.nodesource.com/setup_6.x | bash -

I created the above Dockerfile to run laravel application.
Then i ran docker build -t raheelwp/laravel-app . command and it created the image without name. Then i ran docker tag imageid raheelwp/laravel-app . After this when i check docker images it shows my image with name.
So far so good. But when i run docker run -t raheelwp/laravel-app and then login into container by docker exec -it containerid bash and do the ls on /var/www directory there is no laravel-app folder present there.
I am new to docker and this is my first ever docker file. I would be very thankful to you to please guide me why i am having this problem and how to fix this.
Thanks
I have the following docker file that I am attempting to use to build a Ubuntu image with mono.
FROM ubuntu:14.04
MAINTAINER John Smith <John.Smith#gmail.com>
RUN sudo apt-get update
RUN sudo /bin/bash -l -c apt-get install wget
RUN sudo /bin/bash -l -c apt-get http://download.mono-project.com/repo/xamarin.gpg
RUN sudo apt-key add xamarin.gpg
RUN sudo echo "deb http://download.mono-project.com/repo/debian wheezy main" > /etc/apt/sources.list.d/mono-xamarin.list
RUN sudo apt-get update
RUN sudo apt-get install mono-complete
When I run the following docker build command...
docker build -t="test/mono" .
It fails building and gives the following errors message:
gpg:can't open 'xamaring.gpg': No such file or directory.
2015/05/27 16:11:01 The command [/bin/bash -c sudo apt-key add xamarin.gpg] returned a non-zero code: 2
Anything obviously wrong sticking out?
It looks like you forgot to use wget instead of apt-get after you installed wget, so 'xamaring.gpg' has not been downloaded and that's why it can't be found.
You need this:
/bin/bash -l -c "wget http://download.mono-project.com/repo/xamarin.gpg"
The is an example of this in docker's website:
