Initialize database using Docker
The purpose of this tutorial is to show how to initialize a database MariaDB required for Soffid IAM installation using Docker.
1. Install docker ( https://docs.docker.com/install/ )
2. Create a docker network, that network allows you to connect containers to the same bridge network to communicate:
sudo docker network create -d bridge NETWORKNAME
For the correct installation of Soffid it is recommended not to use the underline character _ in the network name.
sudo docker exec -i -t ID_CONTAINER /bin/bashMySQL/MariaDB
First step will be initialize MariaDB with Docker, in this case we attach the container to an exist network:
sudo docker run -d --name mariadb-service --network=NETWORKNAME -e "MYSQL_ROOT_PASSWORD=ADMIN_PASSWORD" mariadb
Second, you can check the deployed containers:
sudo docker ps
Then, you must connect to the created container:
sudo docker exec -i -t mariadb-service /bin/bash
In order to configure MySQL database you need access to the database administration tool (mysql) with superuser permissions using a TCP/IP connection. If needed, please create a user for the Soffid installation. If you don't have such a user, or don't know its password, please access MySQL as root, execute the mysql tool and create the user with grant command (where ADMIN_USER is the user to be used during the installation process to create the soffid repository database and ADMIN_PASSWORD is the required password).
Coonect to MySQL:
mysql -u root -p
Create database and grant permissions:
create database soffid; use soffid; grant all privileges on *.* to ADMIN_USER@'%' identified by 'ADMIN_PASSWORD' with grant option;
In addition, in order to be able to manage big files, like process definition or software addons, we have to modify max_allowed_packet parameter on MySQL. This parameter is commonly allocated on the /etc/mysql/my.cnf file.
If the version of MariaDB is 10.1.38, or newer, the recommended value for max_allowed_packet is 512M
Note: in the case we will obtain the next 'The size of BLOB/TEXT data inserted in one transaction is greater than 10% of redo log size. Increase the redo log size using innodb_log_file_size.' error trying to upload an addon, we may update the default value of this mysql/mariadb parameter. This parameter is commonly allocated on the /etc/mysql/my.cnf file.
If you are installing on a Ubuntu 18.04 server, default character set is set to utf8mb4. Using this character set can cause problems, as many index sizes will exceed maximum key size of 767 bytes. To prevent this problem, change following settings:
Alternatively, if UTF character set is required, write the following settings:
