ProfileCredentialsProvider：java.lang.IllegalArgumentException：配置文件不能为空

Question

我正在尝试通过以下方式创建AWSCredentials对象：

AWSCredentials cred =  new ProfileCredentialsProvider("Rafael_Nascimento").getCredentials();

凭证文件位于~/.aws文件夹 (Linux)，如下所示：

# Move this credentials file to (~/.aws/credentials)
# after you fill in your access and secret keys in the default profile
# WARNING: To avoid accidental leakage of your credentials,
#          DO NOT keep this file in your source directory.
[default]
aws_access_key_id =  <default_key>
aws_secret_access_key = <default_secret_key>
[Rafael_Nascimento]
aws_secret_access_key = <secret_key_Rafael_Nascimento>
aws_access_key_id = <key_Rafael_Nascimento>

当我运行代码时，我就在那一行：

Exception in thread "main" java.lang.IllegalArgumentException: profile file cannot be null
    at com.amazonaws.util.ValidationUtils.assertNotNull(ValidationUtils.java:37)
    at com.amazonaws.auth.profile.ProfilesConfigFile.<init>(ProfilesConfigFile.java:142)
    at com.amazonaws.auth.profile.ProfilesConfigFile.<init>(ProfilesConfigFile.java:133)
    at com.amazonaws.auth.profile.ProfilesConfigFile.<init>(ProfilesConfigFile.java:100)
    at com.amazonaws.auth.profile.ProfileCredentialsProvider.getCredentials(ProfileCredentialsProvider.java:135)

有什么问题？ 谢谢！

Answer 1

我的应用程序无法找到凭据文件。 我通过创建全局环境变量（在/etc/environment文件中）解决了这个问题： AWS_CREDENTIAL_PROFILES_FILE="/home/rafael/.aws/credentials"

确保您的应用程序可以看到该变量：

 System.out.println(System.getenv("AWS_CREDENTIAL_PROFILES_FILE"));
    //output: /home/rafael/.aws/credentials

只是为了最终帮助那些失去太多时间使用 docker 面对这个问题的人。

只需使用-v ~/.aws:/root/.aws标志启动 docker docker run命令即可
