Try removing the `table` part from your `--format` argument, such as:

    docker ps --format &#39;{{.Names}}&#39;

It should give you a simple list of container names with no table heading

Here is how we query the other columns with `docker ps`.

Names: 

    docker ps --format &#39;{{.Names}}&#39;

ID:

    docker ps --format &#39;{{.ID}}&#39;

Image:

    docker ps --format &#39;{{.Image}}&#39;

Command:

    docker ps --format &#39;{{.Command}}&#39;
Created:

    docker ps --format &#39;{{.RunningFor}}&#39;

Status:

    docker ps --format &#39;{{.Status}}&#39;
Ports:

    docker ps --format &#39;{{.Ports}}&#39;


More information can be found [here.][1]


  [1]: https://docs.docker.com/engine/reference/commandline/ps/#formatting

Just a combination command, it is prettified with `table`.

```
$ docker ps --format &quot;table {{.Image}}\t{{.Ports}}\t{{.Names}}&quot;

IMAGE               PORTS                NAMES
nginx               0.0.0.0:80-&gt;80/tcp   nginx
```

In addition you can add it to `.docker/config.json` file that will allow you to customize the output of your `docker ps` command.

add to `~/.docker/config.json`:
```
{
  &quot;psFormat&quot;: &quot;table {{.ID}}\\t{{.Image}}\\t{{.Status}}\\t{{.Names}}&quot;
}
```

By using this : 

    Text(new DateTime.fromMillisecondsSinceEpoch(values[index][&quot;start_time&quot;]*1000).toString(), 

I am getting the type of format attached in the picture, however I was wondering if I could get it in `dd/MM/YYYY hh:mm`??

How to run jq from gitbash in windows?

I recently installed anaconda2 on my Mac. By default Conda is configured to activate the base environment when I open a fresh terminal session.

I want access to the Conda commands (i.e. I want the path to Conda added to my `$PATH` which Conda does when initialised so that&#39;s fine).


However I don&#39;t ordinarily program in python, and I don&#39;t want Conda to activate the base environment by default.

When first executing `conda init` from the prompt, Conda adds the following to my `.bash_profile`:

    # &gt;&gt;&gt; conda initialize &gt;&gt;&gt;
    # !! Contents within this block are managed by &#39;conda init&#39; !!
    __conda_setup=&quot;$(&#39;/Users/geoff/anaconda2/bin/conda&#39; &#39;shell.bash&#39; &#39;hook&#39; 2&gt; /dev/null)&quot;
    if [ $? -eq 0 ]; then
        eval &quot;$__conda_setup&quot;
    else
    if [ -f &quot;/Users/geoff/anaconda2/etc/profile.d/conda.sh&quot; ]; then
        . &quot;/Users/geoff/anaconda2/etc/profile.d/conda.sh&quot;
    else
        export PATH=&quot;/Users/geoff/anaconda2/bin:$PATH&quot;
    fi
    # fi
    unset __conda_setup
    # &lt;&lt;&lt; conda initialize &lt;&lt;&lt;

If I comment out the whole block, then I can&#39;t activate any Conda environments.

I tried to comment out the whole block except for

    export PATH=&quot;/Users/geoff/anaconda2/bin:$PATH&quot;

But then when I started a new session and tried to activate an environment, I got this error message:

    CommandNotFoundError: Your shell has not been properly configured to use &#39;conda activate&#39;.

[This question](https://askubuntu.com/questions/849470/how-do-i-activate-a-conda-environment-in-my-bashrc) (and others like it) are helpful, but doesn&#39;t ultimately answer my question and is more suited for linux users.

To be clear, I&#39;m not asking to remove the `(base)` from my `$PS1` I&#39;m asking for Conda not to activate base when I open a terminal session.



How do I prevent Conda from activating the base environment by default?

(I am using MAC)

My id_rsa starts with

    -----BEGIN OPENSSH PRIVATE KEY-----

but I expect it to starts with 

    -----BEGIN RSA PRIVATE KEY-----

I have send my id_rsa.pub to server administrator to get the access to server, so I don&#39;t want to generate a new key. 

1. Is there any way that I can transfer my id_rsa which is a openssh private key to a RSA private key?  (command please.)

2. If I can transfer, do I also need to transfer id_rsa.pub? (command please.) It seems id_rsa.pub doesn&#39;t have a header like id_rsa, so I am not sure if I should also transfer this.



Openssh Private Key to RSA Private Key

After updating miniconda3, whenever I open a terminal it shows &quot;(base)&quot; in front of my username and host.

In this answer post https://askubuntu.com/a/1113206/315699 it was suggested to use

    conda config --set changeps1 False

To remove it.

But that would remove the indication for any conda environment. I would like to remove it only for the base one, so that I can maintain it always active and have access to its python and installed packages without having to always see this (base) taking up space.

How to remove (base) from terminal prompt after updating conda

I am hoping to run a simple shell script to ease the management around some conda environments.  Activating conda environments via `conda activate` in a `linux` os works fine in the shell but is problematic within a shell script.  Could someone point me into the right direction as to why this is happening?

Example to repeat the issue:

    # default conda env
    $ conda info | egrep &quot;conda version|active environment&quot;
         active environment : base
              conda version : 4.6.9

    # activate new env to prove that it works
    $ conda activate scratch
    $ conda info | egrep &quot;conda version|active environment&quot;
         active environment : scratch
              conda version : 4.6.9

    # revert back to my original conda env
    $ conda activate base 

    $ cat shell_script.sh
    #!/bin/bash
    conda activate scratch

    # run shell script - this will produce an error even though it succeeded above
    $ ./shell_script.sh
    
    CommandNotFoundError: Your shell has not been properly configured to use &#39;conda activate&#39;.
    To initialize your shell, run
    
        $ conda init &lt;SHELL_NAME&gt;
    
    Currently supported shells are:
      - bash
      - fish
      - tcsh
      - xonsh
      - zsh
      - powershell
    
    See &#39;conda init --help&#39; for more information and options.
    
    IMPORTANT: You may need to close and restart your shell after running &#39;conda init&#39;.


Python - Activate conda env through shell script

So I have used the default docker for testcafe which on docker hub is testcafe/testcafe and I have to run a few testcafe scripts.  

However, I need the screenshot that fires on error, to be uploaded to somewhere where I can look at it later after the docker image is done running.  

I am using the Imgur program which uses bash so I re-did a few things to make it sh compatible and everything works except I need curl.  I tried running 

    apk add curl

but I&#39;m getting the error 

    ERROR: Unable to lock database: Permission denied ERROR: Failed to open apk database: 

Now I no this means that I do not have permission to do this but can I get around this is there some way to become root (this is in bitbucket pipeline).  


I do NOT really want to create my own docker.

Also note all questions I have found relating to this are about installing while creating the docker, however, my question is how to do this after the docker is created.  thx (a fine answer would be another way to save the screen shot, but preferably not with ssh).

I have the following docker-compose file 

    version: &#39;3&#39;
    services:
        node1:
                build: node1
                image: node1
                container_name: node1
    
        node2:
                build: node2
                image: node2
                container_name: node2

I can build both images and start them with a single command

`docker-compose up -d --build`

But I would like to use build-args on the builds. The original build script of the image outside of the scope of compose looks something like this

    #!/bin/sh
    docker build \
    --build-arg ADMIN_USERNNAME_1=weblogic \
    --build-arg ADMIN_PASSWORD_1=weblogic1 \
    --build-arg ADMIN_NAME_1=admin \
    --build-arg ...
    --build-arg ... \
    -t test/foo .

Both images would use build-args of the same name but different value. Also, as there are dozens of build args, it would be convenient to store them in a compose service specific build-properties file. Is this possible with docker-compose?

I have installed docker on windows 10 pro. I am facing an issue while running the following command in git-bash. 

docker-compose up -d --build

and got following error.

    Error executing command, exiting

I was trying to pull a docker image from a docker registry but hit the following issue:

    $ docker pull &lt;docker registry&gt;/&lt;image name&gt;/&lt;tag&gt; 
    Error response from daemon: Get &lt;docker registry&gt;/v1/_ping: x509: certificate signed by unknown authority

I tried with &quot;curl&quot; and get a similar error message:

     curl performs SSL certificate verification by default, using a &quot;bundle&quot;
     of Certificate Authority (CA) public keys (CA certs). If the default
     bundle file isn&#39;t adequate, you can specify an alternate file
     using the --cacert option.

So I downloaded the CA certificate and imported to the server (RedHat Linux 7) with the following commands:

    cp root_cert.cer /etc/pki/ca-trust/source/anchors/
    update-ca-trust

After the root cert is imported, I can see `curl` is working fine as it won&#39;t complain the cert error, however if I use `docker pull` I still have the same issue. Is `docker` using different ca-cert location than `curl`? How do I fix the issue with `docker pull` in this situation?

Why is Docker trying to create the folder that I&#39;m mounting? If I cd to C:\Users\szx\Projects

    docker run --rm -it -v &quot;${PWD}:/src&quot; ubuntu /bin/bash

This command exits with the following error:

    C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon: error while creating mount source path &#39;/c/Users/szx/Projects&#39;: mkdir /c/Users/szx/Projects: file exists.

I&#39;m using Docker Toolbox on Windows 10 Home.
