When your compose file is set up, you just need one command to execute all of your configured containers. These containers can "communicate" so Docker-compose also enables you to configure containers networks and volumes to store shared data. It is a tool that you will surely use later, to define and execute multiple containers. This is a file grouping a set of commands needed to generate a container from a given Docker image. The container is an (configured) instance of a given image on your Docker machine. Image embed minimum required libraries in order to make you application executable. You will install your containers on this machineĪn image represent an application / service you want to install as a Docker container. This is the host machine for the Docker engine. Here are a few words you will always see going deeper into Docker. Kinematic client to manage your containers Then follow this "Getting started" guide: Then you can create an account on Docker Hub, the entry point for all your Docker's images: For that you can go directly here, every steps are well explained (package size about 500Mb): The first step is to install Docker Engine on your machine. PhpMyAdmin container installed in a few clicks It's really fast and you just have to configure it to target the existing MySQL database.Īnd, in a very few steps, we get access to our MySQL database using a new container: Note how we connect to the 'MySQL container' using "docker exec".īut you can also install a new docker container with PhpMyAdmin ! This simple command enables you to type your SQL Commands from a command prompt. Using MySQL batch docker exec -it expdb_db_1 mysql -u root -p using a batch composing your SQL commands In Docker, you still have several possibilities to do that, like on a real Linux server: Ok that's cool, but I need to manage my Database. Scenario 2: managing your Database with phpMyAdmin Pre requisite is to install Docker engine Containers need less resources than a traditional VM. but it's also faster to backup if needed > Now you can see that you just need one environment: Sometimes, it's not so obvious because of network configuration. then your development environment must have access to this Linux server. there are many (traditional) steps to setup, configure, securize, backup your server and SQL instance. you need to get access to a Linux server (it can be a virtual machine) Using a Linux Server (can be a Virtual Machine) or you can install on your Windows development machine, something like a WAMP server, then configure it. you can do the same with a cloud service like Azure So you have to configure your server, then install MySQL then you need to restore Dumps and configure it to be accessed from the outside. you own a remote Linux server that you can use to install a MySQL instance on. To setup / test your application you have several possibilities: Scenario 1: using a MySQL database Imagine, you are working on a project (a Windows one) that use a database like MySQL. There are already many available images on Docker hub website (see links at bottom). To install wanted applications, you will surely use Docker images. In a container, you can install applications (like MySql) or services (like nodejs). You don't need to install a full OS anymore. So it's much more lightweight / easy to configure. Containers are isolated spaces that contain only libraries used to execute wanted applications or services. Over the 'Docker engine' layer, we will setup containers. Docker engine will (after being installed as we will see just after), comes in place of the traditional Hypervisor. For Docker, we talk about a Docker machine. Perhaps though I am misisng something really important.- Both VMs and containers will be installed on a (dedicated) machine. Using powershell and appropriate commands to achieve the same as the linux style command line intends I have been able to continue. Where do you type that? the syntax is wrong for powershell or command prompt and WSL doesn't know about npm so there must be some other pre-requsite knowledge or something missing in the Setup section. Mkdir test-node-app & cd test-node-app & npm init -y & code. "Next command creates a new folder with name test-node-app, then creates npm package file and opens folder in VS Code. The effort you have gone to here looked promising so I have signed up to this site just to see if you still monitor this old topic and might have a response. I have reviewed a lot of tutorials and I have found ever one of them to be missing vital information (some are outright wrong). For a topic that appeared to be aimed at new docker user and using Windows system with VS Code as I have, I did not expect to be stumped so soon. Some pre-requisite knowledge that you have not explained.
