I try i setup a Shopware Docker Container for development. I setup a Dockerfile for the Shopware initialize process but every time i run the build process shopware return this error message:
mysql -u 'root' -p'root' -h 'dbs' --port='3306' -e "DROP DATABASE IF EXISTS `shopware6dev`"
ERROR 2005 (HY000): Unknown MySQL server host 'dbs' (-2)
i think docker setup the default network after all build processes are done but i need to connect before all containers are ready. The depends_on option brings nothing. I hope anyone have a idea to solve this problem.
This is my docker-compose file:
version: '3'
services:
shopwaredev:
build:
context: ./docker/web
dockerfile: Dockerfile
volumes:
- ./log:/var/log/apache2
environment:
- VIRTUAL_HOST=shopware6dev.test,www.shopware6dev.test
- HTTPS_METHOD=noredirect
restart: on-failure:10
depends_on:
- dbs
adminer:
image: adminer
restart: on-failure:10
ports:
- 8080:8080
dbs:
image: "mysql:5.7"
volumes:
- ./mysql57:/var/lib/mysql
environment:
- MYSQL_ROOT_PASSWORD=root

restart: on-failure:10
nginx-proxy:

- "443:443"
volumes:
- /var/run/docker.sock:/tmp/docker.sock:ro
- ./ssl:/etc/nginx/certs
restart: on-failure:10
and this is my dockerfile for web shopwaredev container:

due to hardware problem, I had to replace my small home server with a new one.
Several self-hosted services with Docker were running on the server for which I tried to backup the volumes following the instructions on the official Docker website and those present in this YouTube video and in this cheat-sheet. Now, following the same documentation, I am trying to restore the backups but without success. The first one I'm trying for is a stack for Nginx Proxy Manager built with Docker compose with this docker-compose.yaml file:
version: "3.6"
services:
app:
image: jc21/nginx-proxy-manager:latest
restart: always
ports:
- "80:80"
- "443:443"
- "81:81"
environment:
DB_MYSQL_HOST: "db"
DB_MYSQL_PORT: 3306
DB_MYSQL_NAME: "db_name"
DB_MYSQL_USER: "db_user"
DB_MYSQL_PASSWORD: "db_password"
volumes:
- data:/data
- ./letsencrypt:/etc/letsencrypt
depends_on:
- db
db:
image: jc21/mariadb-aria:latest
restart: always
environment:
MYSQL_DATABASE: "db_name"
MYSQL_ROOT_PASSWORD: "root_password"
MYSQL_USER: "db_user"
MYSQL_PASSWORD: "db_password"
volumes:
- db:/var/lib/mysql
volumes:
db:
data:
After starting the stack with docker compose up -d command I'm trying to restore db and data volumes with:
docker run --rm --volumes-from nginx-proxy-manager-db-1 -v $(pwd):/backup ubuntu bash -c "cd / && tar xvf /backup/nginx-proxy-manager_db_20220717-082200.tar --strip 1"
docker run --rm --volumes-from nginx-proxy-manager-app-1 -v $(pwd):/backup ubuntu bash -c "cd / && tar xvf /backup/nginx-proxy-manager_data_20220717-082200.tar --strip 1"
What's wrong?
I'm really confused why I'm unable to make API requests to any site. for example, I want to run :
HTTParty.get("https://fakerapi.it/api/v1/persons")
It runs well on my machine. (without docker).
But if I run it inside docker, I got :
SocketError (Failed to open TCP connection to fakerapi.it:443 (getaddrinfo: Name does not resolve))
It happens not only for this site. But for all sites.
So I guess there's something wrong with my docker settings. But I'm not sure where to start.
I'm new to docker. So any advice means a lot to me.
Below is my docker-compose.yaml
version: '3.4'
services:
db:

How I try to run:
docker-compose run backend /bin/sh
rails c
HTTParty.get("https://fakerapi.it/api/v1/persons")
Any idea how can I fix this?

I am new to docker. I am trying to containerise my Go application using docker-compose.
Technology used
Golang, Docker 20.10.8 and Air (for live reloading).
My Dockerfile looks like this.
FROM base as dev
WORKDIR /opt/app/api
RUN apk update
RUN apk add git gcc musl-dev
RUN apk add curl
RUN curl -sSfL https://raw.githubusercontent.com/cosmtrek/air/master/install.sh | sh -s -- -b $(go env GOPATH)/bin
# RUN go get
# RUN go mod tidy
CMD ["air"]
My docker-compose.yml is this.

On running command sudo docker-compose up -d I am getting the following error
Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "air": executable file not found in $PATH: unknown
As mentioned in "docker: executable file not found in $PATH":
When you use the exec format for a command (in your case: CMD ["air"], a JSON array with double quotes) it will be executed without a shell.
This means that most environment variables will not be present.
CMD air should work, provided:
air is an executable (chmod 755)
air was cross-compiled to Linux (unless your host running docker is already Linux)
I have the following docker-compose.yml.
version: "3.1"
services:
db:
container_name: ${MYSQL_CONTAINER}
image: mysql:5.7.30

restart: on-failure
backend:

image: ${BACKEND_IMAGE}
depends_on:

command: >
bash -c "command A

restart: unless-stopped
I am scaling backend service so my startup command is sudo docker-compose -p ${COMPOSE_PROJECT_NAME} up -d --scale backend=10.
The problem I am facing is command A, command B in service backend was running for all 10 containers startup(means they were being run 10 times).
But I want command A to run only once for all the backend service-related containers but Command B should run for all containers.
Any suggestions in accomplishing this?
I'm not entirely sure that there would be an out-of-the-box solution for your requirement.
However, I can suggest you a workaround like this. You can duplicate your backend service in docker-compose and run one backend service with both Command A and Command B, while the other backend has only Command B.
Then when you want to scale, you scale the backend which has only Command B.
version: "3.1"
services:
db:
container_name: ${MYSQL_CONTAINER}
image: mysql:5.7.30
volumes:
- ${VOLUMES_DIR}/mysql_data:/var/lib/mysql
- ./slow_log.cnf:/etc/mysql/my.cnf
- ${VOLUMES_DIR}/mysql_logs:/var/log/mysql
environment:
- MYSQL_ROOT_PASSWORD=${MYSQL_PASSWORD}
- MYSQL_USER=${MYSQL_USER}
ports:
- ${MYSQL_PORT}:3306
entrypoint: ""
command: bash -c "chown -R mysql:mysql /var/log/mysql && exec /entrypoint.sh mysqld --default-authentication-plugin=mysql_native_password"
restart: on-failure
backend_default:
container_name: ${BACKEND_CONTAINER}
image: ${BACKEND_IMAGE}
depends_on:
- db
ports:
- ${BACKEND_PORT}
command: >
bash -c "command A
&& command B
&& ... "
restart: unless-stopped
backend:
container_name: ${BACKEND_CONTAINER}
image: ${BACKEND_IMAGE}
depends_on:
- db
ports:
- ${BACKEND_PORT}
command: >
bash -c "command B
&& ... "
restart: unless-stopped
Now you can use the scale option like below:
sudo docker-compose -p ${COMPOSE_PROJECT_NAME} up -d --scale backend=9
Now if there happens to be a scenario, where you need only 1 backend to be run, you can use profiles in docker-compose to only run backend when there is a specific profile is given with docker-compose command. That means only default_backend will run if that profile is not given and hence the scale is 1.
Hope this helps you. Cheers 🍻 !!!
If BACKEND_IMAGE is being built by you, you should do RUN command A in your Dockerfile. The RUN line will be executed only once during build time — so you will also need to make sure that this meshes with your needs — while the ENTRYPOINT and CMD lines will only be run upon execution of the container. The command in the docker-compose file overrides the CMD line.
I am on the Mac with docker install version 2.0.0.3 (31259)

This is happening due to postges running locally on your machine on the same port you have mentioned in your docker-compose.yml for postges service.
Either stop the sevice running on your local machine.(not recommended)
Or use other port to map to 5432 port of docker. To do so replace the
expose
-5432
in postgresa service with the following code
ports:
- "5433:5432"
The whole docker compose file will look like:
