Install `ip` command package for Ubuntu.

    apt update
    apt install iproute2

I have tried `hostname -I`. Working fine for me.No need to install a new package.

Unfortunately, your link has been broken (or it might be inaccessible from Iran). Although there is not enough evidence of which Linux OS you are trying to use, a solution is provided as follow work under **.deb** (e.g. Ubuntu) and **.rpm** (e.g. Fedora) package managers.

At first, update the container&#39;s repository:
Ubuntu:

    apt-get update

CentOS:

    yum update

Fedora:

    dnf update

Secondly, install net-tools package.
Ubuntu:

    apt-get install net-tools

CentOS:

    yum install net-tools

Fedora:

    dnf install net-tools

Lately, **ifconfig** has been replaced with **ip** command. So make sure to check both commands, some Linux distributions have not changed the command yet.

for command `ip` not found in centos 7, you can use `yum install iproute -y ` to fix.

for command `ifconfig` not found in centos 7, you can use `yum install net-tools -y` to fix.


Although OP was on Windows 10. I landed on this question searching for a fix for macOS and didn&#39;t find [this answer](https://superuser.com/a/898971/290915) for a while. So I&#39;m linking it here as well just in case

You can install `ip` tool on OS X via brew:

```
brew install iproute2mac
```

Your link doesn&#39;t work. 

Do `docker ps` or `docker images` in GitBash to see if the docker containers and images are running. 

I recommend installing Docker Community Edition if you are running Win 10. Make sure u have Hyper-V enabled. 

I&#39;ve recently been playing with the Javascript Fetch API. As far as I understand, by default all redirects are handled transparently and in the end I get a response from the last call in the redirect chain.

However, I could invoke fetch with {redirect: &#39;manual&#39;}, in which case it would return an opaqueredirect response with no usable information. From https://fetch.spec.whatwg.org/#concept-filtered-response-opaque-redirect

&gt; An opaque-redirect filtered response
is a filtered response whose type is &quot;opaqueredirect&quot;, status is 0, status message is the empty byte sequence, header list is empty, body is null, and trailer is empty.

https://fetch.spec.whatwg.org/#http-fetch says that a response gets to be opaqueredirect if redirect is set to &#39;manual&#39;:

&gt; Switch on request’s redirect mode:&lt;br/&gt;
&gt; ...&lt;br/&gt;
&gt; - manual&lt;br/&gt;
&gt; &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Set response to an opaque-redirect filtered response whose internal response is actualResponse. 

The specification also says:
&gt; In other words, an opaque filtered response and an opaque-redirect filtered response are nearly indistinguishable from a network error.

Given all this, why would one set redirect to manual when using the Fetch API? To me it seems pretty useless. Are there use cases where this would be useful?

Fetch API - What&#39;s the use of redirect: manual

I need to write a program using the (experimental) `C++17` filesystem library but `clang` on my **Mac (macOS 10.12.03)** doesn&#39;t seem to have the filesystem header included.

Since I&#39;m required to use the `C++17`, I cannot use alternatives like the `Boost` library. 

When I try to compile a sample program that just includes filesystem and `iostream` (and writes to `cout`)

    #include &lt;filesystem&gt;
    #include &lt;iostream&gt;
    using namespace std;

    int main(){
    	cout &lt;&lt; &quot;test&quot; &lt;&lt; endl;
    }

I get the following error message:

    &gt;clang test.cpp -std=c++1z

    test.cpp:2:10: fatal error: &#39;filesystem&#39; file not found
    #include &lt;filesystem&gt;
             ^
    1 error generated.

When I try the same using GCC 6.3 (installed via homebrew) I get:

    &gt;gcc-6 test.cpp  -std=c++17 
    test.cpp:2:22: fatal error: filesystem: No such file or directory
     #include &lt;filesystem&gt;
                          ^
    compilation terminated.

I also tried using experimental/filesystem instead which compiles using `gcc` but seems to try to compile for iOS leading to another error which seems to be related to `iostream`

I&#39;m grateful for any helpful input since I couldn&#39;t find anything that solved my problem so far (although I might have been searching for the wrong terms).

If you need more information I&#39;ll gladly provide it but I hope to have included everything.

I&#39;m currently trying to set up a hyperledger fabric network using docker toolbox, based on the guide [HERE][1]

When it comes to &quot;Starting up validating peers&quot; step, I followed and entered `ip add` into the terminal, but it returns `bash: ip: command not found`. Any solution? I&#39;ve tried `ifconfig` as well and it&#39;s the same issue, command not found.

I am running docker-nginx on ECS server. My nginx service is suddenly stopped because the `proxy_pass` of one of the servers got unreachable. The error is as follows:

I have many servers in the config file, even if one server was down, I need to have running nginx. Is there any way to fix it?

Any suggestion to fix this issue would be appreciated.

Docker Nginx stopped: [emerg] 1#1: host not found in upstream

Is it possible to create `Dockerfile` that executes a command on host when image is being build?

**Now I&#39;m doing:**

    ./script_that_creates_magic_file.sh
    docker build .

with Dockerfile:

    FROM alpine
    COPY magic_file

**I want to be able to do:**

    docker build .

with Dockerfile:

    FROM alpine
    # invoke script_that_creates_magic_file.sh on the host
    COPY magic_file

Of course, this script is in the same directory as Dockerfile.

Inside my `docker-compose.yml`, I have the following `service` `healthcheck` section. I want to know if MariaDB is actually ready to handle queries. A `service` named `cmd` is configured to depend on `condition: service_healthy`.

      db:
        image: mariadb:10
        environment:
          MYSQL_RANDOM_ROOT_PASSWORD: 1
          MYSQL_USER: user
          MYSQL_PASSWORD: password
          MYSQL_DATABASE: database
        healthcheck:
          test: [&quot;CMD&quot;, &quot;mysql&quot;, &quot;--user=user&quot;, &quot;--password=password&quot;, &quot;--execute=&#39;SELECT 1&#39;&quot;, &quot;--host=127.0.0.1&quot;, &quot;--port=3306&quot;]
          interval: 1s
          retries: 30

This healthcheck does not work, shows that the service is unhealthy.

How do I check the output of the `test` CMD?

How to view docker-compose healthcheck logs?

I&#39;m following a tutorial about Jenkins pipeline and I can get a &quot;hello world&quot; working under at node 6.10 docker container.

But, when I added a default EmberJS app (using `ember init`) to the repo and attempt to build that in the pipeline, it fails when running npm install (because of directory access issues). The Jenkinsfile can be seen here: https://github.com/CloudTrap/pipeline-tutorial/blob/fix-build/Jenkinsfile

The error message printed by the build is (which is installed locally and run using `java -jar jenkins.war` on a Macbook, not relevant but included just in case) is:

    npm ERR! Linux 4.9.12-moby
    npm ERR! argv &quot;/usr/local/bin/node&quot; &quot;/usr/local/bin/npm&quot; &quot;install&quot;
    npm ERR! node v6.10.0
    npm ERR! npm  v3.10.10

    npm ERR! Please try running this command again as root/Administrator.

Note: I would like to *not* run `npm install` as root / sudo.

UPDATE: I have been able to make some progress as follows:

I found the command that Jenkins uses to build using the container from the logs:

    [Pipeline] withDockerContainer
    $ docker run -t -d -u 501:20 -w /long-workspace-directory -v /long-workspace-directory:/long-workspace-directory:rw -v /long-workspace-directory@tmp:/long-workspace-directory@tmp:rw -e

So when the docker image runs, it&#39;s work directory is a `/long-workspace-directory` (it&#39;s really a cryptic looking jenkins workspace path) and the user id is 501 (group id 20), etc. The user doesn&#39;t have a name (which is apparently breaking other things not related to this question).

1. Changed agent to use a Dockefile:

    &lt;!-- language: lang-groovy --&gt;

        agent {
          dockerfile {
            filename &#39;Dockerfile&#39;
            args &#39;-v /.cache/ -v /.bower/  -v /.config/configstore/&#39;
          }
        }

2. Specify `args &#39;-v ...&#39;` for creating volumes for the directories npm install / bower needs.

npm install fails in jenkins pipeline in docker

I needed space and executed: `docker rmi $(docker images -f &quot;dangling=true&quot; -q)`

Since then I can&#39;t with docker-compose: `docker-compose build`, I get the error: `ERROR: Error processing tar file(exit status 1): unexpected EOF`.

I tried to remove all images, reinstall docker, but nothing will do: always the same error, after quite some time.

I built on another system and it worked, which *suggests* that this is a wrong-state issue.

Any idea what I should clean?

I installed Git on my **Windows 10** a couple of months ago. It worked well for some time. But now, it&#39;s running very slow.

The `git status` command takes **7 seconds** to execute, and `git stash` takes **many minutes** for stashing (even if there is nothing to stash). Also, I would like to point out that `git status` prints the result instantaneously, but I can not enter a new command for a few seconds, as shown in the image below.

[![The screen is stuck like this for 7 seconds][1]][1]

I have tried solutions to similar problems like [link1][2], [link2][3], etc., but none of these have worked.

**P.S.:** I use Windows Defender antivirus, and it is **NOT** making my Bash slow. Also, **cmd** takes more time to execute `git` commands while **git bash** takes longer to run any command.

----

**Update:** I have switched to Ubuntu, and therefore, I don&#39;t use Windows presently. So, there is no way I can check if any of the solutions work for me. I have accepted the answer provided by [@pschild][4] since it has the most upvotes and seems to have worked for many people.

I just installed Windows 10 Creators Update (version 10.0.15063).

I have multiple versions of Visual Studio installed (2012, 2013, 2015 and 2017). I installed VS 2017 only a couple weeks ago.

### Problem

CMake (version 3.8.1) no longer finds the C/C++ compiler when run inside a &quot;VS2015 x64 Native Command Prompt&quot; (it _does_ work properly when run inside a VS 2017 command prompt).

### Reproduction

Content of `CMakeLists.txt`:

&lt;!-- language: lang-none --&gt;

    project (test)
    add_executable (test test.cpp)

(Content of `test.cpp` is irrelevant.)

CMake invocation, in a VS2015 x64 Native Command Prompt:

&lt;!-- language: lang-none --&gt;

    &gt; mkdir build
    &gt; cd build
    &gt; cmake -G &quot;Visual Studio 14 2015 Win64&quot; ..

CMake output:

&lt;!-- language: lang-none --&gt;

    -- The C compiler identification is unknown
    -- The CXX compiler identification is unknown
    CMake Error at CMakeLists.txt:1 (project):

    See also &quot;D:/dev/cmaketest/build/CMakeFiles/CMakeError.log&quot;.

### Analysis

The reason of the failure is clear when looking at `CMakeFiles/CMakeError.log`:

&lt;!-- language: lang-none --&gt;

`rc.exe` (Resource Compiler) is not found. Indeed, in the same VS 2015 command prompt:

&lt;!-- language: lang-none --&gt;

    &gt; where rc.exe
    INFO: Could not find files for the given pattern(s).

While it _is_ found in a VS 2013 command prompt:

&lt;!-- language: lang-none --&gt;

    &gt; where rc.exe
    C:\Program Files (x86)\Windows Kits\8.1\bin\x64\rc.exe
    C:\Program Files (x86)\Windows Kits\8.1\bin\x86\rc.exe

and a VS 2017 command prompt:

&lt;!-- language: lang-none --&gt;

    &gt; where rc.exe
    C:\Program Files (x86)\Windows Kits\10\bin\10.0.15063.0\x64\rc.exe

Checking the content of the `PATH` environment variables in various VS command prompts:

- Inside a VS 2013 command prompt, `PATH` contains

    &lt;!-- language: lang-none --&gt;

        C:\Program Files (x86)\Windows Kits\8.1\bin\x64

- Inside a VS 2017 command prompt, `PATH` contains

    &lt;!-- language: lang-none --&gt;

        C:\Program Files (x86)\Windows Kits\10\bin\x64
        C:\Program Files (x86)\Windows Kits\10\bin\10.0.15063.0\x64

- But inside a VS 2015 command prompt, `PATH` only contains

    &lt;!-- language: lang-none --&gt;

        C:\Program Files (x86)\Windows Kits\10\bin\x64

  which does not contain `rc.exe`.

### Questions

1. Is this a known issue or is it specific to my system?

2. What could Windows 10 Creators Update possibly install, uninstall or alter in the system (perhaps something related to Windows SDKs) that would trigger this problem?

3. What is a clean way to resolve this?

I am using windows 10 task scheduler to run tasks that require me using my personal user account (its necessary to use my user and not system user because of permission issues - I am part of an organization).
In windows 7 computers everything worked fine but as we upgraded to win 10 I cant run the tasks without using the System user (as mentioned before it doesn&#39;t work because of permissions).
I get the following error 

**Additional Data: Error Value: 2147943726**

all I found online was an advice to use the system user other then that nothing :-(

please save my day.

here is a picture of the settings that I want to change.

I installed Anaconda 4.4.0 (Python 3.6 version) on Windows 10 by following the instructions here: [https://www.continuum.io/downloads][1]. However, when I open the Command prompt window and try to write 

    conda list

I get the 

&gt; &#39;conda&#39; command is not recognized...

error. 

I tried to run

    set PATH=%PATH%;C:\Users\Alex\Anaconda3

but it didn&#39;t help. I also read that I might need to edit my `.bashrc` file, but I don&#39;t know how to access this file, and how I should edit it.
