Outdated message for failed minikube ISO download

[larrikinventures]

Thanks for k8s!

The related issue link in the console output for minikube start is outdated and sends me to a 404 - https://github.com/kubernetes/minikube/issue/3922

As an aside, the download always hangs at around 1%. I'm not sure if it's some kind of timeout, but it's always a different percentage, roughly around a MB into the download. I can download https://storage.googleapis.com/minikube/iso/minikube-v1.0.0.iso from Firefox just fine, but the command line download is super choppy (as in, download for 10s, hang for 1 minute, download for 10s, hang for 1 minute, repeat). I ended up manually copying the downloaded file from Firefox into the cache folder which worked. Note - I'm in Australia with a slow connection.

💡  Advice:        A firewall is likely blocking minikube from reaching the internet. You may need to configure minikube to use a proxy.

You are behind a firewall. Please use this link to set proxy:
https://github.com/kubernetes/minikube/blob/master/docs/http_proxy.md

Unfortunately I'm not. The console output already linked me there but there is no appropriate proxy - I'm just at home, connected via my router, no firewall configured. As I said the connection is slow, but the odd hanging at intervals is unique to the ISO download.

Anyway, this ticket is for the bad link in that console output. Not sure if it's supposed to point somewhere else or should just be removed.

[manish1635]

I hope you already tried these:
set HTTP_PROXY=null
set HTTPS_PROXY=null
set NO_PROXY=localhost,127.0.0.1,10.96.0.0/12,192.168.99.1/24,192.168.39.0/24

If not works, Then not sure about your broadband configuration. However, you could check with your provider to give you some proxy IP.

The docker-env variables apply to the docker engine and the proxy environment variables ares needed by the engine to pull docker images.

https://storage.googleapis.com/minikube/iso/minikube-v1.0.0.iso is NOT a docker image. Its the virtual machine boot image. Docker engine is not pulling it. minikube downloads it. Does minikube observe these environment variables when it downloads the boot image? I don't think it does. I expect minikube reads proxy environment from the shell environment (or powershell context).

My corporate proxy works for me. I can download stuff. So this is not a network issue. When minikube attempts to download the virtual machine's boot image, it is NOT using the proxy, I think, even with these --docker-env vars correctly set.

I can get this to work, and I'm not a powershell programmer:
invoke-webrequest https://storage.googleapis.com/minikube/iso/minikube-v1.0.0.iso

I do this:
netsh winhttp set proxy proxy-server="http=xxxxxxxxx:NNNN;https=xxxxxxxxxx:NNNN"
$wcl = new-object system.net.webclient
$wcl.headers.add("user-agent", "PowerShell Script")
$creds = get-credential
$wcl.proxy.credentials=$creds
[net.servicepointmanager]::securityprotocol = [net.securityprotocoltype]::tls12
invoke-webrequest https://storage.googleapis.com/minikube/iso/minikube-v1.0.0.iso

And I can download the iso. But minikube cannot, even with all that.

I'm running into a similar issue.

encountered similar problem here. I am able to download from chrome or using wget though.

[wayne-t]

For people who might have the same problem, here is reference for where to put downloaded files to cache. I found it's useful since I had more missing files other than .iso mentioned above.

[jjfraney]

@wayne-t thanks for that link.

For minikube to use your corporate proxy, I discovered it necessary to set proxy for the minikube program and for the docker containers it runs. Both of these are required. My fail was not knowing how to do the former in powershell, but its similar to bash:
$env:HTTP_PROXY="......"
$env:HTTPS_PROXY="....."
$env:NO_PROXY="......"
minikube-windows-amd64.exe start --vm-driver hyperv --docker-env=http_proxy=$Env:HTTP_PROXY --docker-env=https_proxy=$Env:HTTPS_PROXY --docker-env=no_proxy=$Env:NO_PROXY --hyperv-virtual-switch="Default Switch"

I have a followon problem, which I'll enter on a different issue.

[tstromberg]

This should be fixed in v1.0.1. Thanks for reporting the issue!

minikube start problem please help. i have even downloaded the iso file manually and move it in using "mv minikube-v1.7.0.iso /home/irtaza/.minikube/cache/iso" even then it is stuck on " Downloading VM boot image ..."
