I’m doing a graduation project, and I’m about to put my project up to the server, but I’m having trouble with docker-compose.yml
and Dockerfile
files, could you please advise me where I should fix it?
How to fix this error?
nginx: [error] init_by_lua error: /usr/local/share/lua/5.1/kong/cmd/utils/migrations.lua:16: Database needs bootstrapping or is older than Kong 1.0.
To start a new installation from scratch, run ‘kong migrations bootstrap’.
To migrate from a version older than 1.0, migrated to Kong 1.5.0 first.
If you still have ‘apis’ entities, you can convert them to Routes and Services
using the ‘kong migrations migrate-apis’ command in Kong 1.5.0.

Consider running required migration process before launching pythong? E.g.
The error comes from Kong not being able to use the database provided. when you bringing up kong there need to be an additional step of
migrations/bootstrap
to prepare the database to be used by Kong.Since you are using Docker Compose to bring the whole environment up, adding an additional container to do the migration first should be sufficient:
Since you are mounting data volume from/to Kong database, the first run might not work since Kong might start before the migrations finish. If that’s the case, simply wait for Kong to restart automatically and it should work.
