Having trouble sending a request in next.js with Docker during the build process?

Question

Having trouble sending a request in next.js with Docker during the build process?

When utilizing the getStaticProps function to send a request to my backend API from another Docker container, I am encountering an issue. Despite ensuring that the API URL is accurate, the static page fails to be created. This is due to the requirement for the backend to be operational before the static page can be built. Since this process occurs at build-time, the other container is not yet up and running, causing a deadlock scenario.

Given this challenge, what would be the most effective solution? Although I attempted setting the depends_on value for my other container, unfortunately it did not resolve the issue. Can you suggest an alternative approach to address this problem?

javascript docker docker-compose dockerfile next.js

Answer №1

Two potential solutions come to mind.

It seems that the Next.js build is failing because the service it needs is not running. One solution would be to manually build and start the necessary service before building the rest of the project like this:

docker-compose build some_services
docker-compose up -d some_services
docker-compose build the_rest

By doing this, the Next.js app should be able to make the required request. Just remember to configure the ports and networks correctly for everything to work smoothly.

A more advanced option could involve using build-time networks which are available in versions 3.4+. Here's an example snippet from a docker-compose file:

docker-compose.yml

build:
    context: ./service_directory
    network: some_network

For further information, check out Docker-compose network documentation.

Managing a new service's dependency on another service's availability in Docker orchestration can be quite challenging. It's important to note that even with the use of Healthcheck, there is no guarantee that your database will be fully operational before proceeding to the next stage. The depends_on attribute may not provide much assistance as it primarily dictates the order in which services are launched. According to the Docker documentation:

depends_on only ensures that web starts after db and redis have been initiated, not necessarily when they are "ready". The recommended approach by Docker documentation is to utilize a wait-for-it script or the [wait-for][2] command alongside or following the depends-on attribute.

build: next_service
command: sh -c './wait-for db:5432 -- npm start'
depends_on:
  - db

Another alternative is to manually execute separate docker-compose commands, although this method defeats the purpose of Docker orchestration.
