Okteto error building image "failed to solve: content digest sha256: not found

Question

currently, I am trying to create an Okteto development environment with a NodeJS project + Mongo database. I already created an Okteto account and authenticated Okteto with my CLI.

I am using Okteto CLI version 2.3.3 and would like to use the Docker compose file configured for my application. My docker-compose.yml file is as following:

version: '3'

services: 
  app:
    container_name: docker-node-mongo
    restart: always
    build: .
    ports:
      - 3000:3000
    environment:
      DB_HOST: mongo
      DB_PORT: 27017
      DB_USER: kevin
      DB_PASS: Ab12345!
      DB_NAME: devops_week1
    volumes:
     - .:/user/src/app

  mongo:
    container_name: mongo
    image: mongo
    restart: always
    ports:
      - 27017:27017
    environment:
      MONGO_INITDB_ROOT_USERNAME: kevin
      MONGO_INITDB_ROOT_PASSWORD: Ab12345!
    volumes:
      - ./mongo-data:/data/db

Steps I took to create Okteto development environment (inside local repo folder):

1. okteto context use https://cloud.okteto.com
2. okteto up

Unfortunately, I get the following error during okteto up command:

It looks like Okteto is looking for an old volume. I already tried the steps above in a new Okteto namespace and tried the okteto up --reset command hoping that it would clear some cache. What could be the solution to this error?

Answer 1

I figured out a solution to my problem. The problem was about cache as I suspected. What I did to solve the problem:

1. Removed old container, image and volumes
2. docker builder prune --all
3. docker build with --no-cache flag

After that, okteto up was succesful.
