Docker Compose won't build image but tries to pull from Dockerhub - docker

I have a docker-compose.yml file that defines multiple different services. Multiple of those services should be combined into the same image. They do refer to it in their definition. The first one has also the reference to the Dockerfile location, which should allow the build of this image. But since an update of Docker Desktop it seems to no longer be working.
The docker-compose.yml file looks something like this:
version: '3.9'
services:
frontend:
build: .
image: webapp
volumes:
- .:/app
working_dir: /app/src/frontend
command: yarn run serve
ports:
- 8080:8080
backend:
image: webapp
command: ./run_web.sh
env_file:
- .env
ports:
- 8081:80
depends_on:
- db
db:
image: postgres:13
volumes:
- db-data:/var/lib/postgresql/data
environment:
POSTGRES_USER: user
POSTGRES_DB: db
POSTGRES_PASSWORD: XXXXXXXXX
This worked perfectly fine until a few days ago, but now I get an error when trying to built the project.
WARNING: Some service image(s) must be built from source by running:
docker compose build frontend
Error response from daemon: pull access denied for webapp, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
What am I missing?
The Dockerfile is not very spectacular and it builds if I simply call it manually.

Ok, I've seen, that you're using the image name webapp in the frontend service and the backend service.
The frontend service has the build instruction included and will name the builded image webapp. The backend service does not have any build instruction and tries to pull the image webapp from the registry.

It works fine at local machine when I run docker compose up -d only if I have already run composer install otherwise throws following error
It is ok for development purpose I have to run composer install once, but for production, I think it is not right way to manually do composer install every time new version is deployed. Doesn't the command RUN composer install at Dockerfile install the required dependencies? I can see progress bar of dependencies being installed but no vendor folder is generated if I ssh into container. Again it works fine if I ssh into instance and manually install dependencies.
I have deployed a nodejs app also successfully using elastic beanstalk. There the dependencies were installed properly using command RUN npm install at Dockerfile. I don't see any difference in the process. Do I have to include vendor folder also in the zip file?. Please suggest correct way to deploy.

Create database from one docker container in another

I have a program that builds servers automatically whenever we want stakeholders to test a new feature.
Currently I have the following setup:
Container 1 - all (contains nodejs, php and other dependencies)
Container 2 - db (contains the mysql database)
I'm aware that container 1 should be split but this will involve more unnecessary complexity to this stage of development.
Whenever a new feature is completed and ready to be deployed to a stage server we run: yarn run create:server --branchName=new-feature. This will create all of the configuration necessary to bring up our newly created server.
My problem is that whenever I run the command above I need to create a database in db container from all container:
mysql -u root -pxxxx -e "CREATE DATABASE IF NOT EXISTS `xxxx`"
The script main.ts is running in the context of all container, so it is necessary for all to communicate with db.
export const createDatabase = (subdomain: string) => {
const username = process.env.DB_USERNAME;
const password = process.env.DB_PASSWORD;
console.log(`[INFO] Creating database with name \`${subdomain}\``);
// triple back slash is necessary to avoid `command substitution` in some shells
if (isLocalEnviroment()) {
execSync(`docker run -it stage-manager-db mysql -u ${username} -p${password} -e "CREATE DATABASE IF NOT EXISTS \\\`${subdomain}\\\`"`)
} else {
execSync(`mysql -u ${username} -p${password} -e "CREATE DATABASE IF NOT EXISTS \\\`${subdomain}\\\`"`)
}
console.log(`[INFO] Database \`${subdomain}\` created successfully`);
}
On local environment we would like to use docker, while in production everything will sit in the same machine (db, frontendapp and api).
When trying to run the following command docker run -it stage-manager-db mysql -u root -ppassword -e "CREATE DATABASE IF NOT EXISTS master" from all I get
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
I have tried restarting the service with:
service docker restart
which gives
[ ok ] Starting Docker: docker.
but trying to communicate with db from all keeps getting the same error. Upon trying to service docker stop I get:
[....] Stopping Docker: dockerstart-stop-daemon: warning: failed to kill 825: No such process
No process in pidfile '/var/run/docker-ssd.pid' found running; none killed.
failed!
From now on I have tried the several links to fix this issue:
https://github.com/docker/for-linux/issues/52#issuecomment-333563492
https://askubuntu.com/questions/1146634/how-to-remove-docker-from-windows-subsystem
Cannot connect to the Docker daemon at unix:///var/run/docker.sock
Cant uninstall Docker from Ubuntu on WSL
How can I communicate from all container to db container?

I'm fairly new to docker so any approach that I might be doing wrong, please let me know. I have a feeling that this could be done much better so feel free to suggest improvements.
Update
** DO NOT DO THIS **
Instead of deleting this answer I will leave it here so others can see that this is not a secure/valid solution to this problem
By David Maze's comment:
Remember that anyone who can access the Docker socket has unrestricted root-level access over the whole host system. I would not add the Docker socket in casually here.
I was able to make it working by sharing the socket between my host OS and the all container.

build path either does not exist, is not accessible, or is not a valid URL

I tryna figure out docker to run my django rest framework + vue.js project in clouds. I built Dockerfile and docker-compose.yml file to start an ubuntu machine and run the postgresql, vue.js and drf containers. But when I try run docker-compose build I get the following message:

Verify the name of folders because the folder app/adserver-vue needs to exist with the name equal in docker-compose.yml

New code changes exist in live container but are not reflected in the browser

I am using Docker with the open source BI tool Apache Superset. I have added a new file, specifically a .geojson file in the CountryMap directory. Now, when I try to build using docker-compose up --build or make changes in the frontend, Docker is not fully updated, and I get a file not found error when trying to run a query. When I look inside the container via docker exec -it container_id bash, the new file is there.

It is because docker-compose is utilizing cache. If the dockerfile and the docker-compose.yml in not changed it does not recreate the container image. To avoid this you should use the following flag:
--force-recreate
--force-recreate
Recreate containers even if their configuration and image haven't
changed.
For development purposes I like to use the following switch as well:
-V, --renew-anon-volumes
Recreate anonymous volumes instead of retrieving data from the previous containers.

How to define a docker cli service in docker-compose

I have a docker-compose file that runs a few services.
services:
cli:
build:
context: .
dockerfile: docker/cli/Dockerfile
volumes:
- ./drupal8site:/var/www/html/drupal8site
drupal:
container_name: drupal
build:
context: .
dockerfile: docker/DockerFile.drupal
args:
DOC_ROOT: /var/www/html/drupal8site
ports:
- 80:80
volumes:
- ./drupal8site:/var/www/html/drupal8site
restart: always
environment:
APACHE_DOCUMENT_ROOT: /var/www/html/drupal8site/web
mysql:
image: mysql:5.7
ports:
- 3306:3306
volumes:
- ./mysql:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: root
I would like to add another service which will be a container in which I could run CLI commands (composer, drush for drupal, php, etc).
The following Dockerfile was how I initially defined the cli service but it stops right after it is run. How do I define it so it is part of my docker-compose, shares my mounted volume, and I can interactively connect to it and run CLI commands on it ?
FROM php:7.2-cli
#various programs
RUN apt-get update \
&& apt-get install vim --assume-yes \
&& apt-get install git --assume-yes \
&& apt-get install mysql-client --assume-yes
CMD ["bash"]
Thanks,
Yaron
If you want to run automated scripts on docker images this is obviously a job for a ci-pipeline. You can use CloudFoundry or OpenStack to do this.
But there are many other questions in this post:
1.) How can i share my mounted volume:
You can pass a volume with the -v option to a container. e.g.:
docker run -it -d -v $(pwd)/localFolder:/exposedFolderFromDocker mydockerhub/myawesomeimage
2.) Can I interactively connect to it and run CLI commands on it
docker exec -it docker_cli_1 bash
I recommend to implement features of an docker-image to the individual docker-images Dockerfile. For example copying and running a prepared shell-script:
# your Dockerfile
FROM php:7.2-cli
#various programs
RUN apt-get update \
&& apt-get install vim --assume-yes \
&& apt-get install git --assume-yes \
&& apt-get install mysql-client --assume-yes
# individual changes
COPY your_script.sh /
RUN chown root:root /your_script.sh && \
chmod 0755 /your_script.sh
CMD ["/your_script.sh"]
# a folder to expose
VOLUME /exposedFolderFromDocker
CMD ["bash"]
