How does golang import github private library dependencies [duplicate] - go

Question

I'm searching for the way to get $ go get work with private repository, after many google try.
The first try:
$ go get -v gitlab.com/secmask/awserver-go
Fetching https://gitlab.com/secmask/awserver-go?go-get=1
https fetch failed.
Fetching http://gitlab.com/secmask/awserver-go?go-get=1
Parsing meta tags from http://gitlab.com/secmask/awserver-go?go-get=1 (status code 200)
import "gitlab.com/secmask/awserver-go": parse http://gitlab.com/secmask/awserver-go?go-get=1: no go-import meta tags
package gitlab.com/secmask/awserver-go: unrecognized import path "gitlab.com/secmask/awserver-go
Yep, it did not see the meta tags because I could not know how to provide login information.
The second try:
Follow https://gist.github.com/shurcooL/6927554. Add config to .gitconfig.
[url "ssh://git#gitlab.com/"]
insteadOf = https://gitlab.com/
$ go get -v gitlab.com/secmask/awserver-go --> not work
$ go get -v gitlab.com/secmask/awserver-go.git --> work but I got src/gitlab.com/secmask/awserer-go.git
Yes it work but with .git extension with my project name, I can rename it to original but do it everytime $ go get is not so good, is there an otherway?

Answer 1

You have one thing to configure. The example is based on GitHub but this shouldn't change the process:
$ git config --global url.git#github.com:.insteadOf https://github.com/
$ cat ~/.gitconfig
[url "git#github.com:"]
insteadOf = https://github.com/
$ go get github.com/private/repo
For Go modules to work (with Go 1.11 or newer), you'll also need to set the GOPRIVATE variable, to avoid using the public servers to fetch the code:
export GOPRIVATE=github.com/private/repo

Answer 2

The proper way is to manually put the repository in the right place. Once the repository is there, you can use go get -u to update the package and go install to install it. A package named
github.com/secmask/awserver-go
goes into
$GOPATH/src/github.com/secmask/awserver-go
The commands you type are:
cd $GOPATH/src/github.com/secmask
git clone git#github.com:secmask/awserver-go.git

Answer 3

I had a problem with go get using private repository on gitlab from our company.
I lost a few minutes trying to find a solution. And I did find this one:
You need to get a private token at:
https://gitlab.mycompany.com/profile/account
Configure you git to add extra header with your private token:
$ git config --global http.extraheader "PRIVATE-TOKEN: YOUR_PRIVATE_TOKEN"
Configure your git to convert requests from http to ssh:
$ git config --global url."git#gitlab.mycompany.com:".insteadOf "https://gitlab.mycompany.com/"
Finally you can use your go get normally:
$ go get gitlab.com/company/private_repo

Answer 4

For people using private GitLabs, here's a snippet that may help: https://gist.github.com/MicahParks/1ba2b19c39d1e5fccc3e892837b10e21
Also pasted below:
Problem
The go command line tool needs to be able to fetch dependencies from your private GitLab, but authenticaiton is required.
This assumes your private GitLab is hosted at privategitlab.company.com.
Environment variables
The following environment variables are recommended:
export GO111MODULE=on
export GOPRIVATE=privategitlab.company.com # this is comma delimited if using multiple private repos
The above lines might fit best in your shell startup, like a ~/.bashrc.
Explanation
GO111MODULE=on tells Golang command line tools you are using modules. I have not tested this with projects not using
Golang modules on a private GitLab.
GOPRIVATE=privategitlab.company.com tells Golang command line tools to not use public internet resources for the hostnames
listed (like the public module proxy).
Get a personal access token from your private GitLab
To future proof these instructions, please follow this guide from the GitLab docs.
I know that the read_api scope is required for Golang command line tools to work, and I may suspect read_repository as
well, but have not confirmed this.
Set up the ~/.netrc
In order for the Golang command line tools to authenticate to GitLab, a ~/.netrc file is best to use.
To create the file if it does not exist, run the following commands:
touch ~/.netrc
chmod 600 ~/.netrc
Now edit the contents of the file to match the following:
machine privategitlab.company.com login USERNAME_HERE password TOKEN_HERE
Where USERNAME_HERE is replaced with your GitLab username and TOKEN_HERE is replaced with the access token aquired in the
previous section.
Common mistakes
Do not set up a global git configuration with something along the lines of this:
git config --global url."git#privategitlab.company.com:".insteadOf "https://privategitlab.company.com"
I beleive at the time of writing this, the SSH git is not fully supported by Golang command line tools and this may cause
conflicts with the ~/.netrc.
Bonus: SSH config file
For regular use of the git tool, not the Golang command line tools, it's convient to have a ~/.ssh/config file set up.
In order to do this, run the following commands:
mkdir ~/.ssh
chmod 700 ~/.ssh
touch ~/.ssh/config
chmod 600 ~/.ssh/config
Please note the permissions on the files and directory above are essentail for SSH to work in it's default configuration on
most Linux systems.
Then, edit the ~/.ssh/config file to match the following:
Host privategitlab.company.com
Hostname privategitlab.company.com
User USERNAME_HERE
IdentityFile ~/.ssh/id_rsa
Please note the spacing in the above file matters and will invalidate the file if it is incorrect.
Where USERNAME_HERE is your GitLab username and ~/.ssh/id_rsa is the path to your SSH private key in your file system.
You've already uploaded its public key to GitLab. Here are some instructions.

Answer 5

All of the above did not work for me. Cloning the repo was working correctly but I was still getting an unrecognized import error.
As it stands for Go v1.13, I found in the doc that we should use the GOPRIVATE env variable like so:
$ GOPRIVATE=github.com/ORGANISATION_OR_USER_NAME go get -u github.com/ORGANISATION_OR_USER_NAME/REPO_NAME

Answer 6

Generate a github oauth token here and export your github token as an environment variable:
export GITHUB_TOKEN=123
Set git config to use the basic auth url:
git config --global url."https://$GITHUB_TOKEN:x-oauth-basic#github.com/".insteadOf "https://github.com/"
Now you can go get your private repo.

Answer 7

If you've already got git using SSH, this answer by Ammar Bandukwala is a simple workaround:
$ go get uses git internally. The following one liners will make git and consequently $ go get clone your package via SSH.
Github:
$ git config --global url."git#github.com:".insteadOf "https://github.com/"
BitBucket:
$ git config --global url."git#bitbucket.org:".insteadOf "https://bitbucket.org/"

Answer 8

I came across .netrc and found it relevant to this.
Create a file ~/.netrc with the following content:
machine github.com
login <github username>
password <github password or Personal access tokens >
Done!
Additionally, for latest GO versions, you might need to add this to the environment variables GOPRIVATE=github.com
(I've added it to my .zshrc)
netrc also makes my development environment setup better as my personal github access for HTTPS is been configured now to be used across the machine (just like my SSH configuration).
Generate GitHub personal access tokens: https://github.com/settings/tokens
See this answer for its use with Git on Windows specifically
Ref: netrc man page
If you want to stick with the SSH authentication, then mask the request to use ssh forcefully
git config --global url."git#github.com:".insteadOf "https://github.com/"

Answer 9

That looks like the GitLab issue 5769.
In GitLab, since the repositories always end in .git, I must specify .git at the end of the repository name to make it work, for example:
import "example.org/myuser/mygorepo.git"
And:
$ go get example.org/myuser/mygorepo.git
Looks like GitHub solves this by appending ".git".
It is supposed to be resolved in “Added support for Go's repository retrieval. #5958”, provided the right meta tags are in place.
Although there is still an issue for Go itself: “cmd/go: go get cannot discover meta tag in HTML5 documents”.

Answer 10

After trying multiple solutions my problem still persisted. The final solution after setting up the ~/.netrc and SSH config file, was to add the following line to my ~/.bash_profile
export GOPRIVATE="github.com/[organization]"

Answer 11

I have created a user specific ssh-config, so my user automatically logs in with the correct credentials and key.
First I needed to generate an key-pair
ssh-keygen -t rsa -b 4096 -C "my#email.here"
and saved it to e.g ~/.ssh/id_my_domain. Note that this is also the keypair (private and public) I've connected to my Github account, so mine is stored in~/.ssh/id_github_com.
I have then created (or altered) a file called ~/.ssh/config with an entry:
Host github.com
HostName github.com
User git
IdentityFile ~/.ssh/id_github_com
On another server, the "ssh-url" is admin#domain.com:username/private-repo.git and the entry for this server would have been:
Host domain.com
HostName domain.com
User admin
IdentityFile ~/.ssh/id_domain_com
Just to clarify that you need ensure that the User, Host and HostName is set correctly.
Now I can just browse into the go path and then go get <package>, e.g go get main where the file main/main.go includes the package (from last example above) domain.com:username/private-repo.git.

Answer 12

For me, the solutions offered by others still gave the following error during go get
git#gl.nimi24.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
What this solution required
As stated by others:
git config --global url."git#github.com:".insteadOf "https://github.com/"
Removing the passphrase from my ./ssh/id_rsa key which was used for authenticating the connection to the repository. This can be done by entering an empty password when prompted as a response to:
ssh-keygen -p
Why this works
This is not a pretty workaround as it is always better to have a passphrase on your private key, but it was causing issues somewhere inside OpenSSH.
go get uses internally git, which uses openssh to open the connection. OpenSSH takes the certs necessary for authentication from .ssh/id_rsa. When executing git commands from the command line an agent can take care of opening the id_rsa file for you so that you do not have to specify the passphrase every time, but when executed in the belly of go get, this did not work somewhy in my case. OpenSSH wants to prompt you then for a password but since it is not possible due to how it was called, it prints to its debug log:
read_passphrase: can't open /dev/tty: No such device or address
And just fails. If you remove the passphrase from the key file, OpenSSH will get to your key without that prompt and it works
This might be caused by Go fetching modules concurrently and opening multiple SSH connections to Github at the same time (as described in this article). This is somewhat supported by the fact that OpenSSH debug log showed the initial connection to the repository succeed, but later tried it again for some reason and this time opted to ask for a passphrase.
However the solution of using SSH connection multiplexing as put forward in the mentioned article did not work for me. For the record, the author suggested adding the collowing conf to the ssh config file for the affected host:
ControlMaster auto
ControlPersist 3600
ControlPath ~/.ssh/%r#%h:%p
But as stated, for me it did not work, maybe I did it wrong

Answer 13

After setting up GOPRIVATE and git config ...
People may still meeting problems like this when fetching private source:
https fetch: Get "https://private/user/repo?go-get=1": EOF
They can't use private repo without .git extension.
The reason is the go tool has no idea about the VCS protocol of this repo, git or svn or any other, unlike github.com or golang.org them are hardcoded into go's source.
Then the go tool will do a https query before fetching your private repo:
https://private/user/repo?go-get=1
If your private repo has no support for https request, please use replace to tell it directly :
require private/user/repo v1.0.0
...
replace private/user/repo => private.server/user/repo.git v1.0.0
https://golang.org/cmd/go/#hdr-Remote_import_paths

Answer 14

Make sure you remove your previous gitconfigs, I had the same issue.
Previously I executed gitconfig whose token was expired, when you execute the command next time with new token make sure to delete previous one.

Answer 15

first I tried
[url "ssh://git#github.com/"]
insteadOf = https://github.com/
but it didn't worked for my local.
I tried
ssh -t git#github.com
and it shows my ssh is fine.
finally, I fix the problem to tell the go get to consider all as private and use ssh instead of HTTPS.
adding export GOPRIVATE=*

Answer 16

For standalone/final repos, an as a quick fix, why don't just to name the module within the go.mod as a package using your company's domain ... ?
module go.yourcompany.tld/the_repo
go.yourcompany.tld don't even have to exist as a valid (sub)domain...
Also, in the same go.mod you can use replacement block/lines to use private repos previously cloned the same way (within a respective folder cloned also in $GOPATH/src/go.yourcompany.tld) (why do we have to depend too much in GitHub?)
Edit
Needless to say that a private repo usually shall be a private repo, typically a standard git repo, right? With that, why not just to git clone and then go get within the cloned folder?

Answer 17

It's Hard Code In Go Get. Not The Git Reason. So Modify Go Source.
Reason:
repoRootForImportDynamic Will Request: https://....go-get
// RepoRootForImportPath analyzes importPath to determine the
// version control system, and code repository to use.
func RepoRootForImportPath(importPath string, mod ModuleMode, security web.SecurityMode) (*RepoRoot, error) {
rr, err := repoRootFromVCSPaths(importPath, security, vcsPaths)
if err == errUnknownSite {
rr, err = repoRootForImportDynamic(importPath, mod, security)
if err != nil {
err = importErrorf(importPath, "unrecognized import path %q: %v", importPath, err)
}
}
if err != nil {
rr1, err1 := repoRootFromVCSPaths(importPath, security, vcsPathsAfterDynamic)
if err1 == nil {
rr = rr1
err = nil
}
}
So add gitlab domain to vcsPaths will ok.
Download go source code:
vi ./src/cmd/go/internal/vcs/vcs.go
Look for code below:
var vcsPaths = []*vcsPath{
// GitHub
{
pathPrefix: "github.com",
regexp: lazyregexp.New(`^(?P<root>github\.com/[A-Za-z0-9_.\-]+/[A-Za-z0-9_.\-]+)(/[A-Za-z0-9_.\-]+)*$`),
vcs: "git",
repo: "https://{root}",
check: noVCSSuffix,
},
add Code As Follow,XXXX Is Your Domain:
// GitLab
{
pathPrefix: "gitlab.xxxx.com",
regexp: lazyregexp.New(`^(?P<root>gitlab.xxxx\.com/[A-Za-z0-9_.\-]+/[A-Za-z0-9_.\-]+)(/[A-Za-z0-9_.\-]+)*$`),
vcs: "git",
repo: "https://{root}",
check: noVCSSuffix,
},
compile and replace go.
