I have followed the getting started instructions here: https://linkerd.io/2/getting-started/ for installing linkerd but i am not able to install cli of linkerd.

Please see the command below: curl -sL https://run.linkerd.io/install | sh

Please see the error below:

curl: (60) SSL certificate problem: self signed certificate in certificate chain
More details here: https://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option

Can anyone please help me to solve it.

  • Have you tried with -k? `curl -ksL https://run.linkerd.io/install | sh` – Mark Watney May 14 '20 at 08:26
  • Yes i have with -k and --insecure but i am getting same result. Can you please try in your cmd. – Saiteja Prattipati May 14 '20 at 08:28
  • I have tried and it works even without `-k`. Are you behind a proxy or something? Please try using a slightly different command: `wget https://run.linkerd.io/install; sh install` – Mark Watney May 14 '20 at 08:31
  • You mean curl wget https://run.linkerd.io/install; sh install – Saiteja Prattipati May 14 '20 at 08:37
  • No, only `wget https://run.linkerd.io/install; sh install`. Are you running this on Windows? These commands are meant for Linux or Mac. – Mark Watney May 14 '20 at 08:40
  • You can get the package for windows [here](https://github.com/linkerd/linkerd2/releases/download/edge-20.5.2/linkerd2-cli-edge-20.5.2-windows.exe). – Mark Watney May 14 '20 at 08:43

    To use this package, download it, rename to linkerd.exe and use it according to the instructions. – Mark Watney May 14 '20 at 08:46

    One thing i have observed is that the linkerd cli only works only in the directory of the download exe file from cmd. I was missing this before. – Saiteja Prattipati May 14 '20 at 10:52
  • I am facing new error when i run **linkerd check --pre** the error is **Error rendering install manifest: open /add-ons\grafana/Chart.yaml: file does not exist .** @mWatney can you please help me. – Saiteja Prattipati May 14 '20 at 11:14

The provides installation instructions from the Linkerd website are indeed vague, they provide instruction for Linux (shell) users as well as a brew install command for OSX users.

If you are interested in installing LinkerD on your Windows machine, the recommandation is to download the binary (.exe - for Windows) directly form their release page: https://github.com/linkerd/linkerd2/releases

After you have downloaded the binary, you should be able to update your %PATH% environment variable to add the location of the binary, this will allow you to refer to the linkerd directly from your command prompt.

Linkerd started supporting Windows with a Chocolatey package: https://chocolatey.org/packages/Linkerd2

To use it, make sure that you have Chocolatey installed and run:

choco install linkerd2

After the installation, verify that the install was successful with:

linkerd --help

You should see the list of commands available to the Linkerd CLI.
