Nessie Docker Image

This is the official Docker image for Nessie - a modular database migration tool for Deno.

https://github.com/halvardssm/deno-nessie/

To use the Nessie Docker image, you can either extend it as you normally would and place the config file and migration files in /nessie. The default work directory is /nessie and cmd is set to the nessie cli.

Always use a fixed version for production software to reduce unexpected bugs, and always backup your database before upgrading the nessie version.

Tags

In adition to the versioned tags, which are in sync with the Nessie version, we have latest and next which are always up to date. latest will give you the latest stable release, while next will either be the latest release candidate (unstable version), or equivalent to latest if there are no release candidates. Release candidates mostly occurs only for major releases. As a rule of thumb, you should only use a versioned image for production.

General Usage

Extend dockerfile

FROM halvardm/nessie:latest

# Uncomment this line if your migrations and config file is dependend on a deps.ts file and copy in other dependencies
# COPY deps.ts .

COPY db .
COPY nessie.config.ts .

Build the dockerfile and run it as such:

docker build -t migrations .
docker run -it migrations

Local development

docker run -v `pwd`:/nessie halvardm/nessie init --dialect sqlite
docker run -v `pwd`:/nessie halvardm/nessie make new_migration
docker run -v `pwd`:/nessie halvardm/nessie migrate
docker run -v `pwd`:/nessie halvardm/nessie rollback

If you have a database running in docker, you will have to set up a docker network and connect it to the database container.

docker run -v `pwd`:/nessie --network db halvardm/nessie migrate
