What we think of MariaDB -Without going into too much detail, MariaDB is a lightweight and versatile database that originated as a fork of MySQL. It’s popular for its efficient performance and flexible storage options, making it a strong alternative to both MySQL and PostgreSQL. Many of our websites run on MySQL, and several of our VulpeLab Docker stacks also make use of MariaDB. About MariaDB -MariaDB Server is one of the most popular database servers in the world. It’s made by the original developers of MySQL and guaranteed to stay open source. MariaDB Server turns data into structured information in a wide array of applications, ranging from banking to websites. Originally designed as enhanced, drop-in replacement for MySQL, MariaDB Server is used because it is fast, scalable and robust, with a rich ecosystem of storage engines, plugins and many other tools make it very versatile for a wide variety of use cases. Feature highlightsMySQL compatible – Can easily replace MySQL with minimal or no changes. Multiple storage engines – Choose the best for your workload (InnoDB, Aria, MyRocks, ColumnStore, Spider, etc.). Advanced SQL features – JSON support, window functions, CTEs, dynamic/virtual columns, GIS data. Flexible schema changes – Add or change columns online with minimal downtime. Strong security – Role-based access, encryption (at rest & in transit), audit logging, data masking. Scalable & high availability – Replication, Galera Cluster, sharding, parallel queries, MaxScale for load balancing and failover. Backup & recovery – Full/incremental backups, point-in-time recovery, Flashback to undo transactions. Open source & community-driven – Transparent development, frequent updates, large active community.

Stacks: Subscribers Workshop: PostgreSQL Stacks: Subscribers Workshop: pgAdminThe subscriber workshop comes with a different stack version of PostgreSQL and PGAdmin compared to the open workshop counterpart. What we think of PostgreSQL -Without going into too much detail, PostgreSQL is a highly versatile and secure database that's used in many of the Docker stacks we've submitted on the VulpeLab website. It competes effectively with other popular systems like MySQL and MariaDB, offering top-tier performance and robust security. Many of our stacks will reference this thread for further information. About Journal -PostgreSQL is a powerful, open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads. The origins of PostgreSQL date back to 1986 as part of the POSTGRES project at the University of California at Berkeley and has more than 35 years of active development on the core platform.

To resolve this, you’ll need to update the container settings and make the necessary adjustments. Our subscribers have access to a detailed step-by-step guide with the exact configuration changes required. This includes: How to access and edit the container environment variables What SMTP settings need to be updated Common issues and fixes for e-mail delivery from within Docker Testing your configuration to confirm e-mails are working By following the guide, you’ll be able to restore password recovery functionality quickly and ensure your users receive e-mail notifications as expected.

Guides: Subscribers Workshop: Install/Upgrade/Uninstall Docker If you have tried installing docker to your system but failed to follow the docker.com docs then please do the following. Now before starting, a rule of thumb, make sure your system is up to date. Basic Set-up for installing docker.Step 1. Update the host. $ apt update Step 2. Upgrade the host. $ apt upgrade -y Step 3. Install curl. $ apt install curlStep 3. Install Docker. $ curl -sSL https://get.docker.com | shStep 5 Check if Docker is functioning. $ systemctl status docker Upgrade Docker EngineTo upgrade Docker Engine, download the newer package files and repeat the installation procedure, pointing to the new files. Tip Preview script steps before running. You can run the script with the --dry-run option to learn what steps the script will run when invoked: $ curl -fsSL https://get.docker.com -o get-docker.sh $ sudo sh ./get-docker.sh --dry-run This example downloads the script from https://get.docker.com/ and runs it to install the latest stable release of Docker on Linux: $ curl -fsSL https://get.docker.com -o get-docker.sh $ sudo sh get-docker.sh Executing docker install script, commit: 7cae5f8b0decc17d6571f9f52eb840fbc13b2737 <...> You have now successfully installed and started Docker Engine. The docker service starts automatically on Debian based distributions. On RPM based distributions, such as CentOS, Fedora, RHEL or SLES, you need to start it manually using the appropriate systemctl or service command. As the message indicates, non-root users can't run Docker commands by default. Uninstall Docker EngineUninstall the Docker Engine, CLI, containerd, and Docker Compose packages: $ sudo apt-get purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extrasImages, containers, volumes, or custom configuration files on your host aren't automatically removed. To delete all images, containers, and volumes: $ sudo rm -rf /var/lib/docker $ sudo rm -rf /var/lib/containerdRemove source list and keyrings $ sudo rm /etc/apt/sources.list.d/docker.list $ sudo rm /etc/apt/keyrings/docker.asc You have to delete any edited configuration files manually.
