Midas (cargo-migrate)

So Midas, king of Lydia, swelled at first with pride when he found he could transform everything he touched to gold; but when he beheld his food grow rigid and his drink harden into golden ice then he understood that this gift was a bane and in his loathing for gold, cursed his prayer.

• from In Rufinem, Claudian

Do painless migrations.

Supported Database

• PostgresSQL
• CockroachDB
• MySQL
• MariaDB
• SQLite3
• MSSQL
• Cassandra
• OracleDB

Usage

Using CLI

Here is a sample command line usage of midas.

# PostgresSQL
midas --database 'postgres://postgres:postgres@localhost:5432/startup' --source migrations up

# MySQL/MariaDB
midas --database 'mysql://root:mysql@localhost:3306/startup' --source migrations up

# SQLite
midas --database './data.db3' --source migrations up

or you could also use the cargo migrate to integrate it on your cargo workflow.

NOTE: For SQLite use correct URI filenames as stated here: https://www.sqlite.org/c3ref/open.html#urifilenameexamples

Using on container

Here is a basic setup:

MIGRATION_DIR=$PWD/migrations
mkdir -p $MIGRATION_DIR
docker run --rm -v $MIGRATION_DIR:/app/migrations ghcr.io/ffimnsr/midas-rs:latest --database 'postgres://postgres:postgres@localhost:5432/startup' --source migrations status

You can omit the --source migrations as the source flag would default to migrations. In case you plan to change the mounted volume migrations path then append the --source <path/to/migrations> argument.

Command arguments
