mindwendel can be run just about anywhere. So checkout our Installation Guides for detailed instructions for various deployments. The easiest way to deploy and run mindwendel is using our own docker-compose-prod.yml
file. For instructions, see Setup for Production.
If you want to contribute, jump ahead to Development!
To get started with a development installation of mindwendel, follow the instructions below.
mindwendel is built on top of:
- Fork it (https://github.com/mindwendel/mindwendel/fork)
- Create your feature branch (
git checkout -b fooBar
) - Commit your changes (
git commit -am 'Add some fooBar'
) - Push to the branch (
git push origin fooBar
) - Create a new Pull Request
-
Startup docker compose setup
docker compose up --build -d
-
Setup the database
docker compose exec app mix ecto.setup
-
Start the server
docker compose exec app mix phx.server
-
Go to http://localhost:4000/
-
Open you favorite editor and start developing
-
Open a shell in the docker container to execute tests, etc.
docker compose exec app bash
-
Go to http://localhost:4000/
You can extract new strings to translate by running:
mix gettext.extract --merge
-
Startup docker compose setup
docker compose up --build -d
-
Run the test
docker compose exec app mix test
-
Generate self-signed ssl sertificate for the postgres server on the host machine; the generated files are mounted into the docker container
mkdir -p ./ca openssl req -new -text -passout pass:abcd -subj /CN=localhost -out ./ca/server.req -keyout ./ca/privkey.pem openssl rsa -in ./ca/privkey.pem -passin pass:abcd -out ./ca/server.key openssl req -x509 -in ./ca/server.req -text -key ./ca/server.key -out ./ca/server.crt chmod 600 ./ca/server.key test $(uname -s) = Linux && chown 70 ./ca/server.key
-
Duplicate and rename
.env.prod.default
cp .env.prod.default .env.prod
-
Adjust all configs in
.env.prod
, e.g. database settings, ports, disable ssl env vars if necessary -
Start everything at once (including a forced build):
docker compose --file docker-compose-prod.yml --env-file .env.prod up -d --build --force-recreate
-
Open the browser and go to
http://${URL_HOST}
- The url has to match the env var
URL_HOST
; so http://localhost will not work when yourURL_HOST=0.0.0.0
- The mindwendel production configuration is setup to enforce ssl, see Mindwendel.Endpoint configuration in
config/prod.exs
- The mindwendel production configuration supports deployment behind a reverse porxy (load balancer) by parsing the proper protocol from the x-forwarded-* header of incoming requests, see
config/prod.exs
- If you are having troubles during setup, please raise an issue.
- Build the docker image based on our Dockerfile
docker build -t mindwendel_prod .
We are using Elixir's built-in formatter.
- Check if the code is properly formatted
mix format --check-formatted
- Automatically format the code
mix format
Mindwendel includes a job runner that deletes old brainstormings after a defined number of days. This can be controlled with the setting MW_FEATURE_BRAINSTORMING_REMOVAL_AFTER_DAYS
, which can be set to for instance to 30
.
File storage is available through an s3 compatible object storage backend. An encryption key (VAULT_ENCRYPTION_KEY_BASE64
) needs to be generated before, e.g.:
iex
32 |> :crypto.strong_rand_bytes() |> Base.encode64()
or
openssl rand -base64 32
Then, object storage and the vault key need to be set:
OBJECT_STORAGE_BUCKET: mindwendel
OBJECT_STORAGE_SCHEME: "http://"
OBJECT_STORAGE_HOST: minio
OBJECT_STORAGE_PORT: 9000
OBJECT_STORAGE_REGION: local
OBJECT_STORAGE_USER: ...
OBJECT_STORAGE_PASSWORD: ...
VAULT_ENCRYPTION_KEY_BASE64: ...
There is an example given inside the docker-compose.yml
with a docker compose minio setup.
To deactivate file storage, use MW_FEATURE_IDEA_FILE_UPLOAD
(defaults to true
) and set it to false
.
If you want to display some teasers and help for your brainstorming, use MW_FEATURE_BRAINSTORMING_TEASER
and set it to true
.
Currently, there are two language files available, german (de
) and english (en
). To set the default_locale, you can set MW_DEFAULT_LOCALE
. The default is english.
kits is a project platform hosted by a public institution for quality development in schools (Lower Saxony, Germany) and focusses on digital tools and media in language teaching. mindwendel is used in workshops to activate prior knowledge, and collect and structure ideas. In addition, mindwendel can be found on https://kits.blog/tools and can be used by schools for free.
