You can comment lines by using the `#` character, e.g.

    [default]
    aws_access_key_id = XXXXXXXXX
    aws_secret_access_key = YYYYYYYY

    #[qa]
    #aws_access_key_id = AAAAAAAAA
    #aws_secret_access_key = BBBBBB


I want to call parent method (deletePhone) in child component in Angular 4. 
How can I do that properly?

my parent component looks like:

&lt;!-- language: lang-typescript --&gt;

    export class ContactInfo implements OnInit {
        phoneForm: FormGroup;
        phones: Phone[];
 

        constructor(private fb: FormBuilder,
                private userService: UserService) {
        }

        ngOnInit() {
            this.userService.getDataPhones().subscribe(
                phones =&gt; {
                    this.phones = phones;
                });

            this.phoneForm = this.fb.group({
                phone: [&#39;&#39;, [Validators.pattern(PHONE_PATTERN)]]
            });
        }

        deletePhone(phone: Phone) {
            this.userService.deleteUserPhone(phone)
                .subscribe(res =&gt; {
                    let index = this.phones.indexOf(phone);
                    if (index &gt; -1) {
                        this.phones.splice(index, 1);
                    }
            });
        }
    }

For AWS CLI configuration and credentials files how do you comment out lines in these files - I checked the documentation here http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html#cli-config-files but found nothing.

e.g.

~/.aws/credentials

    [default]
    aws_access_key_id = XXXXXXXXX
    aws_secret_access_key = YYYYYYYY
    
    [qa]
    aws_access_key_id = AAAAAAAAA
    aws_secret_access_key = BBBBBB


~/.aws/config

    [default]
    region = us-east-1
    
    [profile qa]
    region = us-west-2
    
    [profile staging]

I tried to follow this [tutorial][1]. 

This is what I did in the console:

    pip3 install --user --upgrade awscli

after that, when I write: 

    pip3 --version

I&#39;m getting:

    pip 9.0.1 from /Users/user/Library/Python/3.4/lib/python/site-packages (python 3.4)

then I wrote:

    pip3 install --user --upgrade awscli

this command downloaded `awscli` and automatically added this:

    # Setting PATH for Python 3.4
    # The orginal version is saved in .profile.pysave
    PATH=&quot;/Library/Frameworks/Python.framework/Versions/3.4/bin:${PATH}&quot;
    export PATH

to my `.profile`

Later on, just to be sure, I wrote:

    source ~/.profile

and then when I type:

    user$ aws
    -bash: aws: command not found

I restarted the terminal with no luck also. 

What&#39;s the problem here?

A query operation as specified in DynamoDb documentation:

&gt; A query operation searches only primary key attribute values and supports a subset of comparison operators on key attribute values to refine the search process.

and the scan operation:

&gt; A scan operation scans the entire table. You can specify filters to apply to the results to refine the values returned to you, after the complete scan.


Which is best based on Performance and Cost Considerations.

What is the difference between scan and query in dynamodb? When use scan / query?

I&#39;m running a Kubernetes cluster on AWS using kops. I&#39;ve mounted an EBS volume onto a container and it is visible from my application but it&#39;s read only because my application does not run as root. How can I mount a `PersistentVolumeClaim` as a user other than root? The `VolumeMount` does not seem to have any options to control the user, group or file permissions of the mounted path.

Here is my Deployment yaml file:

    apiVersion: extensions/v1beta1
    kind: Deployment

      name: notebook-1
    spec:
      replicas: 1

          - name: notebook-1
            persistentVolumeClaim:

          containers:

We have been asked for my school project to write a Java code that runs in AWS Lambda. It is supposed to get the source code of the specific URLs and then upload it to an S3 bucket. The Java code should be running on AWS Lambda. 

I get the source code to the String variable in Java. Then I have while loop that tries to write the String into a file in /tmp directory. Then the file is uploaded to S3. 

Everything works but I get stuck with one specific URL. I have tracked the problem to this point:

    try {
        BufferedWriter out = new BufferedWriter(new FileWriter(&quot;/tmp/url.txt&quot;));
        out.write(source_code);  //Replace with the string 
        //you are trying to write  
        out.close();
    }
    catch (IOException e) {
        System.out.println(&quot;Exception &quot;);
    }

The weirdest thing is, when I test the code locally, everything works. File is created in /tmp directory on my computer and then it is uploaded to an S3 bucket. However, when I run the code in Lambda, I get the following error:

    Task timed out after 15.00 seconds

Any idea why Lambda fails to write the file into its temp directory in this specific case and it works with others?

AWS Lambda: Task timed out

Based on DynamoDb documentation why would anyone use `updateItem` instead of `putItem`? 

----

* `PutItem` - Writes a single item to a table. If an item with the same primary key exists in the table, the operation replaces the item. For calculating provisioned throughput consumption, the item size that matters is the larger of the two.
* `UpdateItem` - Modifies a single item in the table. DynamoDB considers the size of the item as it appears before and after the update. The provisioned throughput consumed reflects the larger of these item sizes. Even if you update just a subset of the item&#39;s attributes, `UpdateItem` will still consume the full amount of provisioned throughput (_the larger of the &quot;before&quot; and &quot;after&quot; item sizes_).

Difference between DynamoDb PutItem vs UpdateItem?

I am trying to install awscli using pip3 on Linux Mint 17.2 Rafaela.

I am getting the error:

    Traceback (most recent call last):
      File &quot;/home/jonathan/.local/bin/aws&quot;, line 19, in &lt;module&gt;
        import awscli.clidriver
    ImportError: No module named &#39;awscli&#39;

These are the steps I am taking, following the aws installation guide:

    sudo pip install awscli --upgrade --user

everything seems to install fine.

adding to my .bashrc

    export PATH=~/.local/bin:$PATH

then

    source ~/.bashrc

then i try the command

    aws --version

and i get

    Traceback (most recent call last):
      File &quot;/home/jonathan/.local/bin/aws&quot;, line 19, in &lt;module&gt;
        import awscli.clidriver
    ImportError: No module named &#39;awscli&#39;


Can anyone help with this?

EDIT: For anyone visiting this question. There is no way I can test any of these answers because I have since removed this OS and installed Ubuntu. Also I have no need for awscli anymore.

awscli fails to work: No module named &#39;awscli&#39;

Most of the time it happens that we load files in a common S3 bucket due to which it becomes hard to figure out data in it.

How can I view objects uploaded on a particular date?

I have deleted the [AWS credentials](https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html) in `sudo nano ~/.aws/config`. But, the credentials are still in [`aws configure`](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html). Is there a way to reset `aws configure` with clear state?

How Do I Clear The Credentials In AWS Configure?

Updated answer (7/10/2021): For AWS CLI v1, do this:

```bash
export AWS_DEFAULT_PROFILE=user2
```

For AWS CLI v2, the following will work:

```bash
export AWS_PROFILE=user2
```

The full question is below for context:

----------

(1.) After successfully configuring a second profile for the AWS CLI, I unsuccessfully tried to set the profile to user2 in my bash session with the following command:

    export AWS_PROFILE=user2

... per the advice here: https://docs.aws.amazon.com/cli/latest/userguide/cli-multiple-profiles.html

(2.) The following command works: 

```bash
aws s3 ls --profile user2
```

So I know that the AWS CLI and the user2 profile are both working on my computer.

(3.) However, when I subsequently (that is, after entering &quot;export AWS_PROFILE=user2&quot;) try something like:

```bash
aws s3 ls
```

... AWS&#39;s response assumes that I want to query it as the default user (NOT user2)

(4.) So the only way I can use the user2 profile from the command line is by continuing to append &quot;--profile user2&quot; to every single command, which is tedious.


(5.)

```bash
echo $AWS_PROFILE
```

yields:

```bash
&gt;&gt; user2
```

, as expected.


Any idea what&#39;s going on here? I&#39;m sure I&#39;m making some dumb mistake somewhere.
