migrate CLI

Installation

With Go toolchain

$ go get -u -d github.com/mattes/migrate/cli github.com/lib/pq
$ go build -tags 'postgres' -o /usr/local/bin/migrate github.com/mattes/migrate/cli

Note: This example builds the cli which will only work with postgres. In order to build the cli for use with other databases, replace the postgres build tag with the appropriate database tag(s) for the databases desired. The tags correspond to the names of the sub-packages underneath the database package.

MacOS

(todo #156)

$ brew install migrate --with-postgres

Linux (*.deb package)

$ curl -L https://packagecloud.io/mattes/migrate/gpgkey | apt-key add -
$ echo "deb https://packagecloud.io/mattes/migrate/ubuntu/ xenial main" > /etc/apt/sources.list.d/migrate.list
$ apt-get update
$ apt-get install -y migrate

Download pre-build binary (Windows, MacOS, or Linux)

Release Downloads

$ curl -L https://github.com/mattes/migrate/releases/download/$version/migrate.$platform-amd64.tar.gz | tar xvz

Usage

$ migrate -help
Usage: migrate OPTIONS COMMAND [arg...]
       migrate [ -version | -help ]

Options:
  -source          Location of the migrations (driver://url)
  -path            Shorthand for -source=file://path
  -database        Run migrations against this database (driver://url)
  -prefetch N      Number of migrations to load in advance before executing (default 10)
  -lock-timeout N  Allow N seconds to acquire database lock (default 15)
  -verbose         Print verbose logging
  -version         Print version
  -help            Print usage

Commands:
  create [-ext E] [-dir D] NAME
               Create a set of timestamped up/down migrations titled NAME, in directory D with extension E
  goto V       Migrate to version V
  up [N]       Apply all or N up migrations
  down [N]     Apply all or N down migrations
  drop         Drop everyting inside database
  force V      Set version V but don't run migration (ignores dirty state)
  version      Print current migration version

So let's say you want to run the first two migrations

$ migrate -database postgres://localhost:5432/database up 2

If your migrations are hosted on github

$ migrate -source github://mattes:personal-access-token@mattes/migrate_test \
    -database postgres://localhost:5432/database down 2

The CLI will gracefully stop at a safe point when SIGINT (ctrl+c) is received. Send SIGKILL for immediate halt.

Reading CLI arguments from somewhere else

ENV variables
$ migrate -database "$MY_MIGRATE_DATABASE"
JSON files

Check out https://stedolan.github.io/jq/

$ migrate -database "$(cat config.json | jq '.database')"
YAML files
$ migrate -database "$(cat config/database.yml | ruby -ryaml -e "print YAML.load(STDIN.read)['database']")"
$ migrate -database "$(cat config/database.yml | python -c 'import yaml,sys;print yaml.safe_load(sys.stdin)["database"]')"
```
