Git instaweb with multiple repositories not working

Question

I have the following estructure which is populated via grok mirror:

/var/opt/git/git-data/repositories
   /organization1  
      /teamA
        /repo1
        /repo2
      /teamB
        /repo3
        /repo4
  /organizationN          
      /teamN
        /repoN

git instaweb works fine for a individual repo but if I want to automatically git instaweb shows all repos under "repositories" dir it doesnt' work:

fatal: Not a git repository (or any parent up to mount point /var/opt/git/git-data)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).

Which is true because there is no repo in the parent directory, but if I execute git instaweb from /var/opt/git/git-data/repositories/organization/teamA/ I get the same error and inside that directory is where the bare repos resides (a repoN.git directory for each repo)

I have set GIT_DISCOVERY_ACROSS_FILESYSTEM env var without results. Also I have set /etc/gitweb.conf the following entry: our $projectroot = "/var/opt/git/git-data/repositories";

As I have read in doc of the project, git instaweb can serve for multiple repos, not only one and it looks for repos under certain directory.

What am I doing wrong?

Answer 1

I do this by creating an empty repository and linking to the repositories I want to browse. This workaround is necessary because of the complicated way instaweb runs gitweb and sets the project root.

git init instaweb
cd instaweb
ln -s /var/opt/git/git-data/repositories/org1/teama/repo1 repo1-a-1
ln -s /var/opt/git/git-data/repositories/org2/teamb/repo2 repo2-b-2
git instaweb --httpd webrick

The server is up and running now and the homepage will list a .git project (which is the empty repository you just initialised) along with the two actual projects you linked to.
