This is my first dockerfile project with docker-compose. In my project I try create a docker-compose file.

This project result in:

In docker-compose you should create some services and you can link them. for example:
docker-compose.yml
version: '3'
services:
my_app:
build: .
image: my_app:1.0.0
container_name: my_app_container
command: ... # you can run a bash file or a command
I created a docker-compose with my_app service which it can create my_app image.
you can rewrite it with your node container.
Reference
I enabled the tty function in my docker-compose.yml file and works like a chaming (See Reference).
This is my final docker-compose.yml file:
docker-compose.yml
version: '3'
services:
node:
build: node
image: docker_node
ports:
- "8082:3000"
container_name: "brau_io_api"
volumes:
- /app/brau_io/api:/app/
command: /bin/bash
tty: true

I can access to the target with ssh password and with the private key from Jenkins bash, I configured SSH sites on jenkins with the same host, User and private key I get the next error:

I try with the IP and I get the same.

When creating a private key, you should create a code with the following command after version ubuntu 20.04.
ssh-keygen -t ecdsa -m PEM -f remote-key

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:
build path either does not exist, is not accessible, or is not a valid URL
Here is my Dockerfile:
RUN apt-get update && upt-get install -y \
gcc \
musl-dev \
node.js \
postgresql-server-dev-10 \
apt-utils \
python3.7 \

restart: always
vue:
build:
context: ./app/adserver-vue
depends_on:
- rest_framework
command: ['npm run watch']
Please tell me what am I doing wrong?
Verify the name of folders because the folder app/adserver-vue needs to exist with the name equal in docker-compose.yml
Can anybody help me? This docker-compose file worked for me a few days ago with docker command available inside the container, but now it throws: docker: not found inside.
The docker daemon on the host is on /usr/local/bin/docker. It's a mac.
Any idea? Could you help me to try this on yours guys? Thks

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,

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"]
I tried to build a container used docker-compose. So I wrote the dockerfile and docker-compose.yml like following:
dockerfile
FROM ubuntu:latest
RUN apt-get update
RUN apt-get install -y expect
RUN apt-get -y install software-properties-common
RUN apt-add-repository ppa:ondrej/php
RUN apt-get -y install php7.1 php7.1-fpm
RUN apt-get install php7.1-mysql
RUN apt-get -y install nginx
RUN apt-get -y install vim
COPY default /etc/nginx/sites-available/default
COPY www.conf /etc/php/7.1/fpm/pool.d/www.conf
COPY test /var/www/html/test
CMD service php7.1-fpm start && nginx -g "daemon off;"
docker-compose.yml
version: '3'
services:
web:
build:
context: .
dockerfile: Dockerfile
ports:
- "3011:80"
When I run following command, the php7.1-fpm is run success.
docker-compose build
docker-compose up --force-recreate -d
But I want to move the CMD from dockerfile to docker-compose, so I changed the file like following:
docker-compose.yml
command: service php7.1-fpm start && nginx -g "daemon off;"
But this time php7.1-fpm is not running.
How to fix this issue, so that I can run php7.1-fpm in docker-compose.yml?
you can not use service php7.1-fpm start in your Dockerfile, because container is just a process, not a real virtual machine, main process down and others will down neither
docker suggest you to divide them in different container, php-fpm, nginx, single image single container
solution:
docker/php-fpm/Dockerfile
FROM php:7.2-fpm
RUN docker-php-ext-install pdo pdo_mysql mbstring

version: '2.1'

nginx:
