10 Rebuilding pecan API

If you ever make changes to any of the pecan API functions, rebuilding pecan and bringing docker down and up won’t be enough for those changes to show.

You need to rebuild the pecan API docker.

Steps:

After logging in to gruffalo and retina,

go to the docker directory

cd /mnt/shared/projects/joint/202012_RETINA/pecan/docker/

always check to make sure that you’re in the right docker folder with something like docker compose ps which will list all the running containers. If they don’t look familiar, you’re in the wrong place and you’re about to shut down the wrong docker. Turn back!

When you’re ready, bring docker down

docker compose down

Then MOVE TO A NEW DOCKER DIRECTORY: the pecan api docker directory

this is where you will rebuild the API docker

cd apps/api

docker build -t pecan/api:develop .

When this has completed MOVE DIRECTORIES AGAIN back to the pecan docker directory

either with cd ../.. or write out the full path again cd /mnt/shared/projects/joint/202012_RETINA/pecan/docker/

Bring docker up

docker compose up -d

Give it a minute for everything to start. But you might need bring docker up twice because API has some trouble starting.

List all the running containers

docker compose ps

and check to see that pecan/api:develop is up and running and that it has just been updated!
