This example is taken from Prologue’s Example: Todolist with changes from sqlite to mongodb as database.
This is provided with docker-compose.yml and its own Dockerfile to make it reproducible build
on any machine that support Docker.
Set the environment variable of TODOLIST_PATH to point where it resides, or manually change the volumes
field in docker-compose.yml.
In case of just running the example to see how it works, simply run
docker-compose up -d
and it will download all necessary dependencies.
This docker-compose is also provided mongo-express in it so head over
http://localhost:8081
to access mongodb web client.
In case of tweaking the apps, there will be a need to re-build the image several times hence
it’s advisable to run nimble build first to populate nimbledeps package to avoid repeated
download each time the image is built.
To rebuild, run command
docker-compose up -d --build
and this will rebuild the image.
There’s often the case where our app failed running, it’s because mongodb needs some several seconds delay first before it can listen the connection. If we’re in this situation, run the command
docker-compose up -d
to restart its running.
Head over http://localhost:8080 to see the todolist app.
