git-sync
git-sync is a simple command that pulls a git repository into a local directory. It is a perfect "sidecar" container in Kubernetes - it can periodically pull files down from a repository so that an application can consume them.
git-sync can pull one time, or on a regular interval. It can pull from the HEAD
of a branch, or from a git tag, or from a specific git hash. It will only
re-pull if the target of the run has changed in the upstream repository. When
it re-pulls, it updates the destination directory atomically. In order to do
this, it uses a git worktree in a subdirectory of the --root and flips a
symlink.
git-sync can also be configured to make webhook call upon sucessful git repo syncronisation. The call is made when right after the symlink is updated.
Usage
# build the container
make container REGISTRY=registry VERSION=tag
# build the container behind a proxy
make container REGISTRY=registry VERSION=tag HTTP_PROXY=http://<proxy_address>:<proxy_port> HTTPS_PROXY=https://<proxy_address>:<proxy_port>
# run the container
docker run -d \
-v /tmp/git-data:/tmp/git \
registry/git-sync:tag \
--repo=https://github.com/kubernetes/git-sync
--branch=master
--wait=30
# run an nginx container to serve the content
docker run -d \
-p 8080:80 \
-v /tmp/git-data:/usr/share/nginx/html \
nginx
Webhooks
Webhooks are executed asynchronously from the main git-sync process. If a webhook-url is configured,
when a change occurs to the local git checkout a call is sent using the method defined in webhook-method
(default to POST). git-sync will continually attempt this webhook call until it succeeds (based on webhook-success-status).
If unsuccessful, git-sync will wait webhook-backoff (default 3s) before re-attempting the webhook call.
Usage
A webhook is configured using a set of CLI flags. At its most basic only webhook-url needs to be set.
docker run -d \
-v /tmp/git-data:/git \
registry/git-sync:tag \
--repo=https://github.com/kubernetes/git-sync
--branch=master
--wait=30
--webhook-url="http://localhost:9090/-/reload"
