With Go toolchain

Versioned

$ go get -u -d github.com/golang-migrate/migrate/cmd/migrate
$ cd $GOPATH/src/github.com/golang-migrate/migrate/cmd/migrate
$ git checkout $TAG  # e.g. v4.1.0
$ # Go 1.15 and below
$ go build -tags 'postgres' -ldflags="-X main.Version=$(git describe --tags)" -o $GOPATH/bin/migrate $GOPATH/src/github.com/golang-migrate/migrate/cmd/migrate
$ # Go 1.16+
$ go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/migrate@$TAG

Unversioned

$ # Go 1.15 and below
$ go get -tags 'postgres' -u github.com/golang-migrate/migrate/cmd/migrate
$ # Go 1.16+
$ go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/migrate@latest

Notes

Requires a version of Go that supports modules. e.g. Go 1.11+
These examples build 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.
Similarly to the database build tags, if you need to support other sources, use the appropriate build tag(s).
Support for build constraints will be removed in the future: #60
For versions of Go 1.15 and lower, make sure you're not installing the migrate CLI from a module. e.g. there should not be any go.mod files in your current directory or any directory from your current directory to the root

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] [-seq] [-digits N] [-format] [-tz] NAME
           Create a set of timestamped up/down migrations titled NAME, in directory D with extension E.
           Use -seq option to generate sequential up/down migrations with N digits.
           Use -format option to specify a Go time format string. Note: migrations with the same time cause "duplicate migration version" error.
           Use -tz option to specify the timezone that will be used when generating non-sequential migrations (defaults: UTC).

  goto V       Migrate to version V
  up [N]       Apply all or N up migrations
  down [N] [-all]    Apply all or N down migrations
        Use -all to apply all down migrations
  drop [-f]    Drop everything inside database
        Use -f to bypass confirmation
  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 -source file://path/to/migrations -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 -r '.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"]')"
