Can anyone provide a simple, complete node.js lambda function where I can get a secret from secrets manager and use it? I am struggling with the async/await process. I have already tried several suggestions from other posts, but all of them, at the end, can't really use the secret in the main function. For example, I have a main function and call a second function to retrieve the secret:
xxx = retrieve_secret('mysecret');
Then, in the retrieve_secret function I am able to retrieve the secret, I can print it using console.log, but when I try to use it in the main function, it says "Promise ".
Please, help. Thanks in advance!
So, after a few days working on it, I was finally able to solve it:) Here is the code that worked for me:
exports.handler = async (event, context, callback) => {
// Get Secret
var AWS = require('aws-sdk');
var MyPromise = new AWS.SecretsManager();
var Vsecret = await MyPromise.getSecretValue({
SecretId: 'enter-the-secret-id-here'
}).promise();
var MyOpenSecret = JSON.parse(Vsecret.SecretString);
// From here, we can use the secret:
var Vhost = MyOpenSecret.host;
var Vuser = MyOpenSecret.username;
var Vpassword = MyOpenSecret.password;
var Vdatabase = .....
Looking at your question seems you are not able to read response from retrieve_secret('mysecret') method as you have mentioned it return promise, you can read it by using.then() after promise. Try doing this -
xxx.then(res => {
console.log(res)
})
Or here is the code to call get your secret details:
import AWS from "aws-sdk";
getSecretValue(secretName: string): Promise<string> {
const client = new AWS.SecretsManager({
region: '',
accessKeyId: '',
secretAccessKey: '',
});
const secretId = "secretName";
return new Promise((resolve, reject) =>
client.getSecretValue({ SecretId: secretId }, (err, data) => {
if (err) {
reject(err);
} else {
resolve(data.SecretString);
}
})
);
}
