(provider: TCP Provider, error: 35 - An internal exception was caught) Verify that the instance name is correct and that SQL Server is configured to allow remote connections. The server was not found or was not accessible. (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. Info: Įntity Framework Core 2.2.3-servicing-35854 initialized 'ReceptionistContext' using provider '' with options: None I wanted to perform this action by using dotnet ef database update -context ReceptionistContext I have successfully performed the migration using dotnet ef migrations add Initial -context ReceptionistContextīut I am unable to update the database running inside my Docker container. I have prepared a project, following this tutorial. I wanted to integrate an ORM, so I picked up Entity Framework Core. Then restart it to make sure it takes effect: docker-compose exec mysql mysqldump app | gzip > have started to learn ASP.NET Core MVC and I am trying to build an app which makes use of a database. Let's see how to use mysqldump without having to add the password. SET GLOBAL general_log_file = '/var/log/mysql/query.log' mysqldump # Unfortunately, we need to put the password intoĭocker-compose exec mysql mysqldump -u root -proot app | gzip > Without Password We can make sure our changes took place by running the following SQL within Sequel Pro against the database. Restart the container to suck in the new configuration: # Restart:ĭocker-compose up -d Dynamically, can run commands: We'll get these files on our local system when the container is running. We'll update docker-compose.yml to share both the local logs directory and conf.d directory. General-log-file=/var/log/mysql/query.log Docker-Compose Update cnf files to customize how MySQL behaves (we'll be enabling the general database log). # NOTE: WE GRAB THIS SO IT'S STILL THERE, SINCE WE'LL BE OVER-RIDING ITĭocker-compose exec mysql cat /etc/mysql/conf.d/docker.cnf > docker.cnf # and then mount the directory into mysql # Anything loaded here is used, so lets grab docker.cnf We'll grab the logs from conf.d so we can recreate them, as we'll be recreating and customizing these. Let's see inside the container and see where logs belong. We simply connect to it using 127.0.0.1 and port 3306, since the container is sharing port 3306 to our host file system. We can see how to use Sequel Pro to connect to the database. Let's see the created volume: docker volume ls Sequel Pro While we only spin up one container, this still makes it much easier since we need to pass it a decent number of options. We'll use docker-compose to create the mysql container. We'll cover using a MySQL container in development.
