Docker + Composer is not using external providers-url error Composer repositories that have providers can not load the complete list of packages, use getPackageNames instead

[martijn-bigbridge]

Describe the bug
You will get the error below when you use a composer repository inside satis.json that contains a provider-url.

Example file after running the Docker command .composer/cache/repo/https---repo.magento.com/packages.json

{"packages":[],"providers-url":"\/p\/%package%$%hash%.json","provider-includes":{"p\/provider-ce$%hash%.json":{"sha256":"58241c175cc120030c9ca901174fa02981e5bc58e79114c40b0cb7052dd4f4b5"},"p\/provider-ee$%hash%.json":{"sha256":"886f47fee3d8235884a5bc81d87a3d76a41ead199772880cea791b6081ef14a9"},"p\/provider-b2b$%hash%.json":{"sha256":"6e8b73c78b66e76d531c7e2f5acb1c5b4e23bf63502af898192916d295289869"},"p\/provider-marketplace-extensions$%hash%.json":{"sha256":"07ca7c7ba7030a0d710e523dc3cde9d4bf6b71e509ea73a45ac07b28b9d66380"}}}

To Reproduce
satis.json

{
    "name": "x/repo-x",
    "homepage": "https://x.y.z/b",
    "minimum-stability": "dev",
    "providers": true,
    "pretty-print": true,
    "require-all": false,
    "require-dependencies": true,
    "require-dev-dependencies": true,
    "require-dependency-filter": true,
    "archive": {
        "directory": "dist",
        "format": "zip",
        "skip-dev": false
    },
    "repositories": [
        {
            "type": "composer",
            "url": "https://repo.magento.com",
            "name": "magento"
        }
    ],
    "require": {
        "magento/product-community-edition": ">=2.2.6"
    },
}

docker run --rm --init -it \
  --user $(id -u):$(id -g) \
  --volume $(pwd):/build \
  --volume "/Users/martijn/repotest/composer:/composer" \
  composer/satis build /build/satis.json /Users/martijn/repotest/public

Create a free Adobe Magento account for the repo username and password.

Or find another composer repository for satis, that is using (multiple) providers-url's like Magento.

Outcome

In ComposerRepository.php line 351:

build [--repository-url REPOSITORY-URL] [--repository-strict] [--no-html-output] [--skip-errors] [--stats] [--minify] [--] [<file> [<output-dir> [<packages>...]]]

Expected behavior
Accept and follow the providers-url , so you don't get this error.

Additional context
I don't know if this only with Docker.
