For Mac OSX

TL;DR Make sure your "auths" key matches your credential store key exactly

• Check your docker config:

cat ~/.docker/config.json

Sample Result:

{
    "auths": {
        "https://55511155511.dkr.ecr.us-east-1.amazonaws.com": {}
    },
    "HttpHeaders": {
        "User-Agent": "Docker-Client/19.03.5 (darwin)"
    },
    "credsStore": "osxkeychain"
}

Notice that the "auths" value is an empty object and docker is using a credential store "osxkeychain".

• Open Mac's "Keychain Access" app and find the name "Docker Credentials"

Notice the Where: field

• Make sure the auths key in ~/.docker/config.json matches the Where: field in Keychain Access.

If the auths key in ~/.docker/config.json does NOT match they Where: field in the keychain, you may get a Login Succeeded from docker login... but still get ERROR: Service 'web' failed to build: Get https://55511155511.dkr.ecr.us-east-1.amazonaws.com/v2/path/to/image/latest: no basic auth credentials when you try to pull.

In my case, I needed to add https://

Original

    "auths": {
        "55511155511.dkr.ecr.us-east-1.amazonaws.com": {}
    },

Fixed

    "auths": {
        "https://55511155511.dkr.ecr.us-east-1.amazonaws.com": {}
    },
