Nuxt ENV not working in docker container

Apparently, by default, Nuxt only reads system envs that start with "NUXT_", example: "NUXT_DBHOST". So there are 2 solutions: - Change the env names in the docker compose, and add the NUXT prefix to all of them. - Configure nuxt to remove/change the prefix (https://github.com/unjs/nitro/issues/1836#issuecomment-1770116095). This can be done by adding the following to nuxt config:

runtimeConfig: {
        nitro: {
            // Remove mandatory NUXT_ from system runtime variables
            envPrefix: '',
        },
}

runtimeConfig: {
        nitro: {
            // Remove mandatory NUXT_ from system runtime variables
            envPrefix: '',
        },
}

Nuxt ENV not working in docker container

Envs in nuxt are read at build time and injected into the compiled solution. Thanks to the runtime config, it also has the capability of reading runtime system envs

Nuxt ENV not working in docker container

Nuxt runtime config:

runtimeConfig: {
        JWT_SECRET: process.env.JWT_SECRET as string,
        JWT_EXPIRATION: process.env.JWT_EXPIRATION || '900',
        PASSWORD_SALT_ROUNDS: process.env.PASSWORD_SALT_ROUNDS || '10',

        DB_NAME: process.env.DB_NAME,
        DB_HOST: process.env.DB_HOST,
        DB_USER: process.env.DB_USER,
        DB_PASSWORD: process.env.DB_PASSWORD,
        DB_PORT: process.env.DB_PORT || '5432',

        MAX_TRANSACTION_FILE_SIZE: Number(
            process.env.MAX_TRANSACTION_FILE_SIZE || 1024 * 1024 * 10
        ) //10 MB
    },

runtimeConfig: {
        JWT_SECRET: process.env.JWT_SECRET as string,
        JWT_EXPIRATION: process.env.JWT_EXPIRATION || '900',
        PASSWORD_SALT_ROUNDS: process.env.PASSWORD_SALT_ROUNDS || '10',

        DB_NAME: process.env.DB_NAME,
        DB_HOST: process.env.DB_HOST,
        DB_USER: process.env.DB_USER,
        DB_PASSWORD: process.env.DB_PASSWORD,
        DB_PORT: process.env.DB_PORT || '5432',

        MAX_TRANSACTION_FILE_SIZE: Number(
            process.env.MAX_TRANSACTION_FILE_SIZE || 1024 * 1024 * 10
        ) //10 MB
    },

Use of ENV in the code:

const { DB_NAME, DB_HOST, DB_USER, DB_PASSWORD, DB_PORT } = useRuntimeConfig()
console.log(DB_NAME, DB_HOST, DB_USER, DB_PASSWORD, DB_PORT)

const { DB_NAME, DB_HOST, DB_USER, DB_PASSWORD, DB_PORT } = useRuntimeConfig()
console.log(DB_NAME, DB_HOST, DB_USER, DB_PASSWORD, DB_PORT)
