I'm trying to install drupal console in docker (under Linux Antergos). I've the following error :
Warning: mkdir(): Permission denied in phar:///usr/local/bin/drupal/vendor/drupal/console-core/src/Utils/ConfigurationManager.php on line 49
Here is my PHP dockerfile :

To solve the problem I had to install Drupal Console by composer. There is certainly another solution, but it's work with it.

I'm using Docker in a developement environment. I have two pc, both with same OS (kubuntu 20.04) and same docker version.
In one the dockerfile build without errors, in the other fails with
$ docker build -t letsjump/mydockername -f docker-data/webserver73/Dockerfile .
#...lot of compile output...

In both hosts I have the same OS (kubuntu 20.04 desktop) and almost the same Docker version.
In this host the dockerfile build succesfully:

In this other not:

Yes, the dockerfile is probably a mess, with a lot of adds on the fly. But why it compiles in one host and in the other not?
UPDATE
After reading the reasonable answer of aankhen, I emptied the docker-data/webserver73 folder which in any case did not contain any relevant code except one apache virtualhost and one xdebug.ini configuration file in their relative folders.
The build failed again with the same error as above.
I also want to point out that the wevserver73 folder contains the exact same files as the one on the other host with the same owner and rights.
I would expect failures to happen sporadically and periodically with this dockerfile. Why? Because you haven't pinned the versions of the majority of tools you're installing. You implicitly install the latest version of a bunch of GNU/Linux libraries and then explicitly install the latest version of npm and you follow this up by using npm to install the latest version of a bunch of javascript modules. I can see that you pin the versions of some libs, but to guarantee repeatability you have to pin everything.
Also, as #Aankhen said in the comments, you also have a copy command that is copying files from the local filesystem, which could contain anything and again is unlikely to result in a portable repeatable image.
The solution to this is a) pin everything, or b) use a registry to share an image that has been built once and rely on a pinned version of that. Generally, banks and large corporations require the pinning solution, and less regulated industries often go with the registry solution.
I answer to my question:
As Software-engineer said in his answer, pin, pin, pin.
In this case it was the PHP's mantainers (questionable) choice to change the Debian release within a minor version of the docker image (php:7.3-apache). Here they switched from stretch to buster.
So the new pulled php:7.3-apache image had a completely different OS and different dependent library and behaviors.
So, as Software-engineer said, the right and the fastest solution to this problem is to pin the PHP image to a tag related to the distribution: php:7.3-apache-stretch.
The slower and unstable solution, in case you want to use the unpinned version, is to adapt the GD configure options to the new release:
...
docker-php-ext-configure gd --with-gd --with-webp-dir --with-jpeg-dir \
--with-png-dir --with-zlib-dir --with-freetype-dir && \
...
taking care to include the necessary libraries first: libfreetype6-dev, libjpeg-dev and libjpeg62-turbo-dev
But this will require a manual pull from the server for any host that has a non recent build of the same image.
I have a docker Image with the following Entrypoint.
ENTRYPOINT [ "sh", "-c", "/var/www/html/app/Console/cake schema update -y && /var/www/html/app/Console/cake migration && apache2-foreground"]
Now I want to use portainer.io to manage docker swarm. I created a new service to where I want to set the entrypoint (instead of in the Image). So I deleted the entrypoint In the dockerfile, and added it into "Image" > "Entrypoint". I added:
sh -c /var/www/html/app/Console/cake schema update -y && /var/www/html/app/Console/cake migration && apache2-foreground
However, the containers of the service are failing to start. Without the entrypoint, the containers are starting. Here is an example of the Dockerfile, where the Entrypoint is set.

How do I have to set the Entrypoint? When I set it a portainer, it is later shown under the section CDM.
On a debian machine, I suddenly cannot install ssmtp via the following
apt-get update && apt-get install ssmtp
Before it was all working seamlessly up until now.
Also just an FYI.
I am doing this on a dockerFile on a debian container.
Just for your perusal this is the docker file I am running

RUN curl -sSL https://phar.phpunit.de/phpunit.phar -o /usr/bin/phpunit && chmod +x /usr/bin/phpunit
I ran into the same issue, but it has to do with the fact that the package sSMTP package is currently unmaintained.
This package has been orphaned since 2019-03-19. msmtp can be used as an alternative.
So the fix would be replacing your sSMTP package with the suggested msmtp package.
I use docker-compose to build my containers and on a state I checkout private repository and I build the project inside container with composer.
I have the following structure
- docker-project
-- docker //here I keep the containers
--- apache
---- Dockerfile // the content what I posted
-- docker-compose.yml
-- src //this is the mounted folder where I can work on project
After build I would expect that the build project would show up in the mounted folder but instead I get empty folders here is my compose yml

container_name: apache2
build:

What I'm missing in this case?
You are mounting a volume on /var/www when starting the container.
/var/www will be the same as ./src/www on the host machine, replacing anything that was added to /var/www during the build of the image.
Consider using the composer docker image or make sure to install the dependencies to another directory. Check out the vendor_dir key in composer.json
Example:
composer.json
{
"require": {
},
"config": {
"vendor-dir": "/var/www/vendor/"
}
}
Docker image build:
...
RUN mkdir -p /var/www/vendor/
COPY composer.json /var/www/vendor/
RUN cd /var/www/vendor/ && composer install
RUN mkidr -p /var/www/app
...
docker-compose.yml
volumes:
- ./src:/var/www/app
I could give a way of currently we are working. Rather cloning the repo like this what we do, we clone the repo in the local machine.
You have standard docker image that you have created from
php:7.1-apache with required softwares that you need to run the project.
Then you clone your project to you host machine.(think into src folder)
You run the composer install locally.
Then as you have defined the docker-compose.yml mount your src folder into /var/www/
FROM some-build:latest as build
COPY / /var/www/html
WORKDIR /var/www/html
RUN cd /var/www/html && composer install
FROM some-build2:latest as run
COPY --from=build /var/www/html /var/www/html
ENV PATH ${HOME}/local/bin:${PATH}:/home/site/wwwroot
RUN cd /var/www/html && \
npm install && \
npm run production
ENTRYPOINT ["/bin/init_container.sh"]
The image run contains an installed npm. Despite this fact, the npm install return the error: /bin/sh: 1: npm: not found
How is this possible? What am I doing wrong?
Edit:
As answer to #BMitch 's comment, when I run the RUN image, in the container the node is on the PATH and I can use it. The path is /root/local/bin. I've attached all the Dockerfiles.
I have 3 docker files:

Edit 2:
It is important that if I remove the RUN npm... commands, then the whole build is a success and the result image contains the npm and I can use it (I've verified by using a container in interactive mode).
Edit 3:
Here's a lot lot simpler solution that can be tried out instantly:
FROM alpine as img1
RUN echo "$HOME" > $HOME/test.txt
FROM alpine as img2
RUN cat $HOME/test.txt
The result is: cat: can't open '/root/test.txt': No such file or directory
Two issues going on here. The "php:7.2.5-apache" image won't have /root/local/bin in the path, and you did not add it to the path during your build. The npm commands will work when you login interactively likely because of some changes to the shell login scripts that setup the environment. You'll need to run these environment setup scripts before running any npm commands, and that must be done within the same RUN command. To verify for yourself, you can check your .bashrc for variables or commands run to setup the npm environment. And you can verify the environment is different by comparing the PATH value with an env command in the interactive shell and in your build, you should see two different outputs if this is your issue. When I ran part of your run image, I saw the following in the .bashrc:
export PATH=$HOME/local/bin:$PATH
So you'll want to update the line in your Dockerfile for the run image:
ENV PATH /root/local/bin:${PATH}:/home/site/wwwroot
Per your edit 3, that's an entirely different issue. You created a file in one new image, and then went back to the base image where the file doesn't exist. If you wanted to see the file in a multi-stage build, then you either need to copy it between the stages, or use the previous image as your "from".
FROM alpine as img1
RUN echo "$HOME" > $HOME/test.txt
FROM alpine as img2
COPY --from=img1 /root/test.txt /root/test.txt
RUN cat $HOME/test.txt
or
FROM alpine as img1
RUN echo "$HOME" > $HOME/test.txt
FROM img1 as img2
RUN cat $HOME/test.txt
