`docker ps` shows (running) containers. `docker images` shows images.

A successfully build docker image should appear in the list which `docker images` generates. But only a running container (which is an instance of an image) will appear in the list from `docker ps` (use `docker ps -a` to also see stopped containers). To start a container from your image, use `docker run`.

For me, `docker ps -a` and `docker images` both returned an empty list even tho I had many docker containers running. I tried rebooting system with no luck. A quick `sudo systemctl restart docker` fixed this &quot;bug&quot;.

You can run the command without the `-d` option.
So you have the output displayed. 

It may be that the application failed to start.

For me, the only thing resolving the issue is to reinstall docker. Also, one must be sure that the disk is not full.

This is the command that I use, but it may vary depending on the version of docker already installed:

    apt-get install --reinstall docker.io

If prompted, choose &quot;yes&quot; to automatically restart docker daemon

for Linux,

at first, see all the running container
```
sudo docker ps
```
try restarting
```
sudo systemctl restart docker
```

remove previous docker image with the same name if there is any
```
sudo docker rm docker_container_id
```
once again run 
```
sudo docker run -d --name container_name image_name
```
This should work

or uninstall docker and install it again

I tried to follow [this post][1] but got confused rather than getting my problem solved. 

Here is the scenario. 

I have created a branch like `git checkout -b &lt;branch_name&gt;`. I then worked on some changes and did

1. `git add .`
2. `git commit -m &quot;comment&quot;`

Now all those changes are in my uncommitted local `&lt;branch_name&gt;` branch. What i want to do is to push these changes upstream but i want to push it to a branch which doesn&#39;t exist e.g., `&lt;branch_name&gt;_test`

I don&#39;t want to push it to my `&lt;branch_name&gt;`. How can i do so.

How to listen state change in Angular 2 router?

In Angular 1.x I used this event:

    $rootScope.$on(&#39;$stateChangeStart&#39;,
        function(event,toState,toParams,fromState,fromParams, options){ ... })

So, if I use this eventlistener in Angular 2:

    window.addEventListener(&quot;hashchange&quot;, () =&gt; {return console.log(&#39;ok&#39;)}, false);

it isn&#39;t return &#39;ok&#39;, then change state from JS, only then browser history.back() function run.


Use router.subscribe() function as the service:

    import {Injectable} from &#39;angular2/core&#39;;
    import {Router} from &#39;angular2/router&#39;;

    @Injectable()
    export class SubscribeService {
        constructor (private _router: Router) {
            this._router.subscribe(val =&gt; {
                console.info(val, &#39;&lt;-- subscribe func&#39;);
            })
        }
    }

Inject service in component which init in routing:

    import {Component} from &#39;angular2/core&#39;;
    import {Router} from &#39;angular2/router&#39;;

    @Component({
        selector: &#39;main&#39;,
        templateUrl: &#39;../templates/main.html&#39;,
        providers: [SubscribeService]
    })
    export class MainComponent {
        constructor (private subscribeService: SubscribeService) {}
    }


I inject this service in other components such as in this example. Then I change state, console.info() in service not working.

What I do wrong?

Angular 2 router event listener

I built a docker image from a docker file. Build said it succeeded. But when I try to show docker containers through `docker ps` (also tried `docker ps -a`), it shows an empty list. What is weird is that I&#39;m still able to somehow push my docker image to dockerhub by calling `docker push &quot;container name&quot;`.

I wonder what&#39;s going on? I&#39;m on Windows 7, and just installed the newest version of dockertoolbox.

<p>I built a docker image from a docker file. Build said it succeeded. But when I try to show docker containers through <code>docker ps</code> (also tried <code>docker ps -a</code>), it shows an empty list. What is weird is that I'm still able to somehow push my docker image to dockerhub by calling <code>docker push "container name"</code>.</p>

I&#39;m not sure if I have already logged in to a docker registry in cmd line by using cmd: docker login. How can you test or see whether you are logged in or not, without trying to push?

How to know if docker is already logged in to a docker registry server

I finally figured out how to get docker up and running. 

    docker run --name my-forum-nodebb --link my-forum-redis:redis -p 80:80 -p 443:443 -p 4567:4567 -P -t -i nodebb/docker:ubuntu

I linked it to a redis instance, cool. 

This is from scratch and I assume that when I created the redis instance 

    docker run --name my-forum-redis -d -p 6379:6379 nodebb/docker:ubuntu-redis

it pulls the image from a remote repo?

NodeBB offers a `Dockerfile` https://github.com/NodeBB/NodeBB/blob/master/Dockerfile I am not really quite sure how to use it. I am assuming that I can somehow create a local environment by calling this Dockerfile on my remote.

Is this correct? If so how can I create the local instance pointing to the remote?



How do I run a docker instance from a DockerFile?

Beginner Docker question here,

So I have a development environment in which I&#39;m running a modular app, it is working using Docker Compose to run 3 containers: server, client, database.

The `docker-compose.yml` looks like this:


    #############################
    # Server
    #############################
    server:
      container_name: server
      domainname: server.dev
      hostname: server
      build: ./server
      working_dir: /app
      ports:
        - &quot;3000:3000&quot;
      volumes:
        - ./server:/app
      links:
        - database

    #############################
    # Client
    #############################
    client:
      container_name: client
      domainname: client.dev
      hostname: client
      image: php:5.6-apache
      ports:
         - &quot;80:80&quot;
      volumes:
       - ./client:/var/www/html

    #############################
    # Database
    #############################
    database:
      container_name: database
      domainname: database.dev
      hostname: database
      image: postgres:9.4
      restart: always
      environment:
        - POSTGRES_USER=postgres
        - POSTGRES_PASSWORD=root
        - POSTGRES_DB=dbdev
        - PG_TRUST_LOCALNET=true
      ports:
        - &quot;5432:5432&quot;
      volumes:
        - ./database/scripts:/docker-entrypoint-initdb.d # init scripts

You can see I&#39;m assigning a .dev domainname to each one, this works fine to see one machine from another one (Docker internal network), for example here I&#39;m pinging `server.dev` from `client.dev`&#39;s CLI:

        root@client:/var/www/html# ping server.dev
        PING server.dev (127.0.53.53): 56 data bytes
        64 bytes from 127.0.53.53: icmp_seq=0 ttl=64 time=0.036 ms

**This works great internally, but not on my host OS network.**

For convenience, I would like to assigns domains in MY local network, not the Docker containers network so that I can for example type: client.dev on my browsers URL and load the Docker container.

Right now, I can only access if I use the Docker IP, which is dynamic:

    client: 192.168.99.100:80
    server: 192.168.99.100:3000
    database: 192.168.99.100:5432

Is there an automated/convenient way to do this that doesn&#39;t involve me manually adding the IP to my /etc/hosts file ?

BTW I&#39;m on OSX if that has any relevance.

Thanks!

**Edit:** I found this Github issue which seems to be related: https://github.com/docker/docker/issues/2335

As far as I understood, they seem to say that it is something that is not available outside of the box and they suggest external tools like: 

 - https://github.com/jpetazzo/pipework
 - https://github.com/bnfinet/docker-dns
 - https://github.com/gliderlabs/resolvable

Is that correct? And if so, which one should I go for in my particular scenario?

Local hostnames for Docker containers

I&#39;ve cloned a docker setup which uses docker-compose. One remote developer confirms it works so my problem seems to be with my setup. 

I ran `docker-compose up`, but that currently gives me this:

    $ docker-compose up

    Creating volume &quot;mycompanydocker_redis-data&quot; with local driver
    Creating volume &quot;mycompanydocker_app-data&quot; with local driver
    Creating volume &quot;mycompanydocker_mongo-data&quot; with local driver
    mycompanydocker_redis_1 is up-to-date
    mycompanydocker_mongo_1 is up-to-date
    mycompanydocker_mysql_1 is up-to-date

The thing I don&#39;t understand is that `docker-compose` seems to find all `Dockerfile`s, except for the one in the `app` folder. I&#39;ve got the following installed on OSX 10.11.2:

 - `Docker version 1.10.3, build 20f81dd`
 - `docker-compose version 1.6.2, build 4d72027`

I&#39;m just starting out with Docker and I&#39;m kinda stuck here. Does anybody know what could possibly be wrong or how I can debug this? All tips are welcome!

**[EDIT]**&lt;br/&gt;
I forgot to mention that there is no hidden `.dockerignore` file:

    $ ls -la
    total 56
    drwx------@   11 kramer  staff    374 25 mrt 14:13 .
    drwx------+ 1134 kramer  staff  38556 26 mrt 17:27 ..

    drwxr-xr-x@    7 kramer  staff    238 25 mrt 14:26 app
    -rw-r--r--@    1 kramer  staff    868 25 mrt 17:50 docker-compose.yml

    drwxr-xr-x@    3 kramer  staff    102 24 mrt 15:29 redis

and the `.gitignore` file doesn&#39;t contain anything special either (don&#39;t know if it matters):

    $ cat .gitignore
    .project
    .pydevproject

docker-compose gives ERROR: Cannot locate specified Dockerfile: Dockerfile

Is there any way to start an interactive shell in a container using Docker Compose only? I&#39;ve tried something like this, in my docker-compose.yml:

    myapp:
      image: alpine:latest
      entrypoint: /bin/sh

When I start this container using docker-compose up it&#39;s exited immediately. Are there any flags I can add to the `entrypoint` command, or as an additional option to `myapp`, to start an interactive shell?

I know there are native docker command options to achieve this, just curious if it&#39;s possible using only Docker Compose, too.

Interactive shell using Docker Compose

I would like to remove the Docker toolbox completely from my Mac. I tried to remove Docker from the `/Applications` folder, but it didn&#39;t work out.


How to uninstall Docker completely from a Mac?

So I&#39;m using Docker Toolbox because I don&#39;t have Hyper-V on my machine since it&#39;s not Windows 10 pro. Everything seems to work fine, but when I try to go on my browser `0.0.0.0:80` it always returns me: This site can’t be reached

But when I run the command: `docker container ps` I get the following: ` 0.0.0.0:80-&gt;80/tcp` meaning that this address should work. I searched across stackoverflow and github issues. Now I&#39;m stuck. 

Am I missing something? 

Thanks,
Mark

EDIT:

Using `docker-machine ip default` returns me `192.168.99.100`. I run that on port 80. I still get the same result except that the address becomes the container id: `https://fd677edg12`

I run that command on cmd to find my ipv4: `cmd /k ipconfig /all`. Put the result with the port and it returns the same thing: `https://fd677edg12`



Docker Toolbox - Localhost not working

I use Docker toolbox for windows and i`m trying run private docker registry from this documentation https://docs.docker.com/registry/deploying/

But it`s not work for me.

    $ docker pull 192.168.99.100:5000/image
    Using default tag: latest
