Hey,

How did you mount/expose your database to the docker image?

Have you followed the instructions here https://github.com/techouse/sqlite3-to-mysql?tab=readme-ov-file#docker ?

[Akhil]

Mysql is running on host machine, i have exposed it using --mysql-host host.docker.internal as mentioned in your docs. Here is the docker command i have used

I am running it in the location where my sqlite db file is present.

docker run -it \
    --workdir $(pwd) \
    --volume $(pwd):$(pwd) \
    --rm ghcr.io/techouse/sqlite3-to-mysql:latest \
    --sqlite-file <my sqlite file> \
    --mysql-user <mysql_username>\
    --mysql-password <mysql pwd> \
    --mysql-database <db name> \
    --mysql-host host.docker.internal

[Klemen Tusar]

Hmm, looks like this is a known issue and has to do with the fact that the hostname has the port in it. Could you try passing the port separately?

[Akhil]

I am running mysql on its default port 3306. can you share instructions or parameter that I can use for passing port to the image

[Klemen Tusar]

Try using this switch
-P, --mysql-port INTEGER MySQL port. Defaults to 3306.

Also, what's the host OS you're running this on? I've only ever tested this Docker command on macOS.

[Akhil]

Hey @techouse , I have tried adding port. its still the same

docker run -it \
    --workdir $(pwd) \
    --volume $(pwd):$(pwd) \
    --rm ghcr.io/techouse/sqlite3-to-mysql:latest \
    --sqlite-file ***** \
    --mysql-user ****** \
    --mysql-password ***** \
    --mysql-database ***** \
    --mysql-host host.docker.internal \
    --mysql-port 3306

2003: Can't connect to MySQL server on '%-.100s:%u' (%s) (Warning: %u format: a real number is required, not str)

[Akhil]

Even I tried with -P its still same

 docker run -it     --workdir $(pwd)     --volume $(pwd):$(pwd)     --rm ghcr.io/techouse/sqlite3-to-mysql:latest     --sqlite-file ****     --mysql-user ******     --mysql-password ******     --mysql-database ******     --mysql-host host.docker.internal     -P 3306

python tool worked. I have did migration using python. but docker version didn't work

[Klemen Tusar]

Hey @surapuramakhil

I just tried it on macOS 14.3.1 running Docker v25.0.3 and MySQL v8.2.0 running locally on port 3306 and it worked just fine porting this example database using the exact command as in the readme

docker run -it \
    --workdir $(pwd) \
    --volume $(pwd):$(pwd) \
    --rm ghcr.io/techouse/sqlite3-to-mysql:latest \
    --sqlite-file sakila.db \
    --mysql-user foo \
    --mysql-password bar \
    --mysql-database sakila \
    --mysql-host host.docker.internal

[Klemen Tusar]

but docker version didn't work

So I gather your Docker setup is misconfigured?

[Akhil]

I am running it on Linux - Ubuntu 22. Even I have close docker version - 25.0.1

you can also check the commands i have ran along with its output.

Let me know if you need any additional information for debugging

[Klemen Tusar]

Hey,

I simply can'r reproduce it with any demo SQLite db.

Could you maybe send me a snippet of your SQLite database? Maybe it holds some clues.

[Akhil]

Yeah Sure. its an open source project. Apache Answer https://github.com/apache/incubator-answer

I have initially started with project using sqlite. Now migrating it to mysql

[Klemen Tusar]

I'm sorry, maybe I wasn't clear enough. I need a sample of your database that is problematic, otherwise I can not help you.
