![]() ![]() Here’s an explanation of the above command: Our command will look like this:ĭocker run -name=tns_mysql -p3306:3306 -v mysql-volume:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=PWORD -d mysql/mysql-server With our volume ready, we’ll now deploy the MySQL container (named tns_mysql) and connect it to the volume. ![]() To create a volume named mysql-volume, issue the command: The first thing we’re going to do is create a volume for MySQL, so our data will remain persistent, in case the container fails. You’re now ready to deploy the containers. Log out and log back in, so the changes take effect. Sudo apt-get install docker-ce docker-ce-cli containerd.io -y Next, add the official Docker GPG key with:Ĭurl -fsSL | sudo gpg -dearmor -o /usr/share/keyrings/docker-archive-keyring.gpgĪdd the stable Docker repository with the command:Įcho "deb $(lsb_release -cs) stable" | sudo tee /etc/apt//docker.list > /dev/null Sudo apt-get install ca-certificates curl gnupg lsb-release -y To do this, log into your Linux server and install the necessary dependencies with: ![]() ![]() I tend to like to start from scratch, so let’s get Docker up and running first. I’ll be demonstrating this on Ubuntu Server 20.04, but the process will be the same on any platform that supports Docker. With this process, you’ll find working with MySQL database container deployments so much easier. I want to walk you through the process of deploying a MySQL container and then connecting a phpMyAdmin container to that database, for easier management. If you’ve never heard of this tool, it’s a web-based GUI that happens to be the de facto standard UI for MySQL and MariaDB database administration. One way of simplifying the management of your containerized MySQL database deployments is with the help of phpMyadmin. But if your database skills aren’t quite up to that task, how do you make all of this work? If you happen to be a database administrator, you’re probably perfectly at home on the command line. How to make it easier to manage a containerized database. Now that we’re on the same page, you see the problem. However, what about populating that database with data? Or what about managing the database? You can’t just pull down a docker image, deploy a container with it, and assume it will magically populate with the necessary data for your containerized application. To that end, you might deploy MySQL via a Docker container and then connect another container to the database for data. Without the ability to access data, you might find those containers to be a bit less-than-capable. Then navigate to localhost:8080 in your browser and login with username "root" and password "mypass" (leave server field blank).Databases are a key component of your docker containers. # PHP MY ADMIN #Īdd the following line to the "/etc/hosts" file: 127.0.0.1 localhostĪssuming you're also using nginx, and that config is elsewhere in your "docker-compose.yml", you can build and start these services with: docker-compose up -d mysql nginx db phpmyadmin MYSQL_ENTRYPOINT_INITDB=./mysql/docker-entrypoint-initdb.d MYSQL_ROOT_PASSWORD=$Įdit the ".env" file as follows: # MYSQL # Inside "docker-compose.yml" file, under "services": # db # For anyone else having this issue, here is a config that works for mysql and phpmyadmin. The error was not present using docker run.įor docker-compose.yml (version 3), one cause is services running on different networks by default. Out of the box, default config throws this error when you attempt to log into phpMyAdmin (using current images as of Oct 2018). I've had the same error installing docker using laradock, then running docker-compose up. Hint: if docker-compose is not installed on your machine, install it using this official docs (out of scope) That's much simpler - docker run overcomplicates things and is not practical for those things - never. All the links are setup for you automatically. Then start it using docker-compose up in the same folder your docker-compose.yml file is located.Īccess PHPmyadmin using the browser and use 'db' as the hostname of your database, since that is the name of the service in the docker-compose.yml file and therefore can be resolved using dockers internal DNS service to the actual ip of the docker-container. # just if you also want to access it directly from you host Instead of starting them one by one, use docker-compose.Ĭreate a docker-compose.yml file version: '2' ![]()
