Try [this][1]

So, you need to put:

    user: &quot;${UID}:${GID}&quot;

in your docker compose and provide UID and GID as docker-compose parameter

    UID=${UID} GID=${GID} docker-compose up

(or define UID and GID as environment variables).

This can be done as well

**In your docker-composer.yml**

    user: $DOCKER_USER

**In the command line**

    echo &#39;export DOCKER_USER=&quot;$(id -u):$(id -g)&quot;&#39; &gt;&gt; ~/.bash_profile

    source ~/.bash_profile

    docker-compose up

Created a DOCKER_USER variable and added it in the bash_profile for persistency.  The source will  help the shell to recognize changes of .bash_profile on demand

In JavaScript, it&#39;s commonly seen as best practice to use `===` instead of `==`, for obvious and well-known reasons.

In TypeScript, which is one to be preferred? Is there even one which is preferable to the other one?

IMHO, using `===` in TypeScript doesn&#39;t make sense, since comparison already only works on equal types, hence you won&#39;t have the (more or less funny) coercion game as in plain JavaScript. If you take aside compatibility to JavaScript for a minute, TypeScript could even get rid of `===`, couldn&#39;t it?

Why use triple-equal (===) in TypeScript?

I have collectionview inside tableview cell and I use nib for my collection view cell (in which I use autolayout for my imageview and labels and it is on Freeform mode).  I&#39;m setting cell size in tableviewcell class which is handling the delegate for collectionview inside it by this method:

     func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -&gt; CGSize {
            return CGSize(width: 200, height :150)        
        }

It always works but after Xcode 11 it doesn&#39;t.

Why on Xcode 11, UICollectionViewCell changes size as soon as you scroll (I already set size in sizeForItem AtIndexPath:)?

I can execute a `docker run` command as such ... 

    docker run --rm  --user $(id -u):$(id -g) -e MYDATA=/some/path/to/data -e USER=$USER -p 8883-8887:8883-8887 ...

However, in Docker Compose, when I write out the following ... 

    version: &#39;3.7&#39;
    services:
      container_name: some-server
      image: some:img
      user: $(id -u):$(id -g) 
      ... 

... it does not work. 

I understand I am asking `docker-compose up` to perform sub shell command substitution, and it cannot. 

Is there any way to do this?

I thought there&#39;s a problem with my shell, so I followed the instructions to change the default Mac OS shell back to bash, using the GUI and also using the command line: 

```
chsh -s /bin/bash
```

I also restarted the computer. However, I still see the same message, even though `echo &quot;$SHELL&quot;` outputs `/bin/bash`.

I am attempting to utilize the AWS CLI along with a `for` loop in bash to iteratively purge multiple SQS message queues.  The bash script works almost as intended, the problem I am having is with the return value each time the AWS CLI sends a request.  When the request is successful, it returns an empty value and opens up an interactive pager in the command line.  I then have to manually type `q` to exit the interactive screen and allow the `for` loop to continue to the next iteration.  This becomes very tedious and time consuming when attempting to purge a large number of queues.

Is there a way to configure AWS CLI to disable this interactive pager from popping up for every return value?  Or a way to pipe the return values into a separate file instead of being displayed?

I have played around with configuring different return value types (text, yaml, JSON) but haven&#39;t had any luck.  Also the `--no-pagination` parameter doesn&#39;t change the behavior.

Here&#39;s an example of the bash script I&#39;m trying to run:
```
for x in 1 2 3; do 
  aws sqs purge-queue --queue-url https://sqs.&lt;aws-region&gt;.amazonaws.com/&lt;id&gt;/&lt;env&gt;-$x-&lt;queueName&gt;.fifo; 
done
```

How to turn off the pager for AWS CLI return value?

## What I tried

1. I read from [here](https://www.reddit.com/r/debian/comments/ca3se6/for_people_who_gets_this_error_inrelease_changed/) and [here](https://superuser.com/questions/1456989/how-to-configure-apt-in-debian-buster-after-release) that adding `sudo apt-get --allow-releaseinfo-change update` or `sudo apt-get dist-upgrade` could resolve the problem, but even adding those to my workflow didn&#39;t resolve it.

2. I tried using this action [setup-chromedriver](https://github.com/marketplace/actions/setup-chromedriver) but it returned the same error when following the documentation:

    ```yaml
    steps:
    - uses: actions/checkout@v2
    - uses: nanasess/setup-chromedriver@master
      with:
        # Optional: do not specify to match Chrome&#39;s version
        chromedriver-version: &#39;88.0.4324.96&#39;
    - run: |
        export DISPLAY=:99
        chromedriver --url-base=/wd/hub &amp;
        sudo Xvfb -ac :99 -screen 0 1280x1024x24 &gt; /dev/null 2&gt;&amp;1 &amp; # optional
    ```

3. As it seems to be related to _[Debian 10][1] (Buster)_ (?) I also tried to use another Ubuntu runner version as a runner (`ubuntu-18.04` instead of `ubuntu-latest`), but nothing changed, same error.

### How can I resolve this issue?

* * *

&lt;hr/&gt;

### Answer

*I observed afterwards that the problem was happening at the first command : `sudo apt-get update` (and I was adding the other command after...).*

*Substituting it for `sudo apt-get --allow-releaseinfo-change update` resolved my problem.*

*Therefore the answer was not to add the `sudo apt-get --allow-releaseinfo-change update` to the step executed commands, but **substituting** the `sudo apt-get update` command for it.*

I inherited a Kubernetes/Docker setup, and I accidentally crashed the pod by changing something relating to the DB password.

I am trying to troubleshoot this.

I don&#39;t have much Kubernetes or Docker experience, so I&#39;m still learning how to do things.

The value is contained inside the db-user-pass credential I believe, which is an Opaque type secret.

I&#39;m describing it:

    kubectl describe secrets/db-user-pass
    Name:         db-user-pass
    Namespace:    default
    Labels:       &lt;none&gt;
    Annotations:  &lt;none&gt;
    
    Type:  Opaque
    
    Data
    ====
    password:  16 bytes
    username:  13 bytes

but I have no clue how to get any data from this secret. The example on the Kubernetes site seems to assume I&#39;ll have a base64 encoded string, but I can&#39;t even seem to get that. How do I get the value for this?

I have a docker container based on Postgres&#39;s official docker image. I want to see the incoming queries when I look at the logs of the docker container using `docker logs -f`. This is my Dockerfile:
```
FROM postgres:11.1-alpine

COPY mock_data.sql /docker-entrypoint-initdb.d/mock_data.sql

ENV PGDATA=/data
``` 
and this is the part of my docker-compose.yml file related to this service:
```
version: &#39;3&#39;
services:
  mock_data:
    image: mock_data
    container_name: mock_data
    ports:
         - 5434:5432/tcp
```
What is the eaasiest way to include the incoming queries in docker logs?

Im fairly new to docker and so im trying to learn more about it using a laravel project, im following this tutorial:

https://www.digitalocean.com/community/tutorials/how-to-set-up-laravel-nginx-and-mysql-with-docker-compose


Ive adjusted the Dockerfile a bit from what the tutorial has but even the tutorial file causes the same result.

```
FROM php:7.3-fpm

# Copy composer.lock and composer.json
COPY composer.lock composer.json /var/www/
# Install dependencies
RUN curl -sL https://deb.nodesource.com/setup_10.x | bash - &amp;&amp; \
    apt-get update &amp;&amp; apt-get install -y mysql-client \
    

RUN npm install -g npm

# Clear cache
RUN apt-get clean &amp;&amp; rm -rf /var/lib/apt/lists/*


# Install extensions
RUN docker-php-ext-install pdo pdo_mysql

# Install composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

# Add user for laravel application
RUN groupadd -g 1000 www
RUN useradd -u 1000 -ms /bin/bash -g www www

# Copy existing application directory contents
COPY . /var/www

# Copy existing application directory permissions
COPY --chown=www:www . /var/www

# Change current user to www
USER www
# Set working directory
WORKDIR /var/www
# Expose port 9000 and start php-fpm server
EXPOSE 9000

CMD [&quot;php-fpm&quot;]

```

But i keep getting the following error when i run `docker-compose up -d`:

```
E: Package &#39;mysql-client&#39; has no installation candidate
ERROR: Service &#39;app&#39; failed to build: The command &#39;/bin/sh -c curl -sL https://deb.nodesource.com/setup_10.x | bash - &amp;&amp;     apt-get update &amp;&amp; apt-get install -y mysql-client     nodejs     build-essential     vim     git     curl&#39; returned a non-zero code: 100
```

Am i missing something?

I expected this to work since i am running `apt-get update` before installing `mysql-client`.

Thanks.

I have created one node.js project called simpleWeb. The project contains package.json and index.js.

index.js
```js
    const express = require(&#39;express&#39;);
    
    const app = express();
    
    app.get(&#39;/&#39;, (req, res) =&gt; {
      res.send(&#39;How are you doing&#39;);
    });
    
    app.listen(8080, () =&gt; {
      console.log(&#39;Listening on port 8080&#39;);
    });
```
package.json
```json

    {
        &quot;dependencies&quot;: {

        &quot;scripts&quot;: {
          &quot;start&quot;: &quot;node index.js&quot;
        }
      }
```
I have also created one Dockerfile to create the docker image for my node.js project.

Dockerfile

    # Specify a base image
    FROM node:alpine
    
    # Install some dependencies 
    COPY ./ ./
    RUN npm install
    
    # Default command
    CMD [&quot;npm&quot;, &quot;start&quot;]

When I create a GitHub Actions workflow file, the example YAML file contains `runs-on: ubuntu-latest`. [According to the docs](https://help.github.com/en/articles/virtual-environments-for-github-actions#supported-virtual-environments), I only have the options between a couple versions of Ubuntu, Windows Server and macOS X.

I thought GitHub Actions runs inside Docker. How do I choose my Docker image?

This above is supposed to redirect http://whoami.mysite.com to http**s**://whoami.mysite.com.

- The http**s** is working nicely.
- The http don&#39;t redirect to https and raise an error 404.

There is no other file. All is in this Docker-compose.yml for the moment since it is a test to prepare further deployement.

I tried `export DOCKER_BUILDKIT=1` before a `docker-compose build` command and I did not see the expected BuildKit output. What did I miss?

How do you enable BuildKit with docker-compose?

I cannot start keycloak container using ansible and docker-compose. I&#39;am getting error: User with username &#39;admin&#39; already added to &#39;/opt/jboss/keycloak/standalone/configuration/keycloak-add-user.json&#39;

I have 3 ansible jobs:

Create netwrok:

Create keycloak container:

          environment:

Does anyone have any idea why I get this error?

**EDIT**

If I downgrade keycloak to version 7 it starts normally!

Keycloak 8: User with username &#39;admin&#39; already added

I have a docker-compose file and a Dockerfile. MySQL is installed properly. I have set **MYSQL_ROOT_PASSWORD**. But when trying to access mysql db, getting the error - Access denied. I have read the other threads of this site, but couldn&#39;t get that much help. :( 

Here is my docker-compose file:

    version: &#39;3&#39;
    
    volumes:
            db_data: {}
    
    services:
        db:

                dockerfile: ./db/Dockerfile
                args:
                    - database=iTel
                    - password=123
            image: db_image
            volumes:
                - db_data:/var/lib/mysql
            ports:
                - &quot;3306:3306&quot;

and Dockerfile:

Now entered in the container:

    docker exec -it 49419cb9980a bash
    
    root@49419cb9980a:/#

I have checked if MYSQL_ROOT_PASSWORD is set correctly(in the container):

    root@49419cb9980a:/# echo $MYSQL_ROOT_PASSWORD
    123

Then tried to log into mysql:

    root@49419cb9980a:/# mysql -u root -p
    Enter password:
    ERROR 1045 (28000): Access denied for user &#39;root&#39;@&#39;localhost&#39; (using password: YES)

My question is, how to solve this problem? Why can&#39;t I access mysql? I tried with no password option too. 
That gave me this error:

    mysql -u root
    ERROR 1045 (28000): Access denied for user &#39;root&#39;@&#39;localhost&#39; (using password: NO)

This is my project structure:
