Running under restricted networks

This page relates to Recording builds with the Launchable CLI.

The Launchable CLI requires an Internet connection, but your environment might have a limited Internet reachability. This page explains how to deal with it in common cases.

Outbound traffic control

Networks can have a network policy that limits the connections to certain IP addresses and ports. In this case, you need to allowlist Launchable's API server IP addresses. We have an API endpoint that has a stable IP address.

  • Domain: api-static.mercury.launchableinc.com

  • IP Addresses: 13.248.185.38 and 76.223.54.162

  • Port: 443 (HTTPS)

Once your network is configured to allow traffic to the IP addresses above, you can configure the Launchable CLI to use that endpoint:

export LAUNCHABLE_BASE_URL="https://api-static.mercury.launchableinc.com"
launchable verify

Git repository in an Internet unreachable environment

Your repository might have no Internet access for security reasons. For example, the CI workflow would look like:

  1. Check out the Git repository in a machine with no Internet connection.

  2. Build the artifacts in the machine.

  3. Transfer the artifacts to a test environment that has the Internet connection.

  4. Run tests against the artifacts in the test environment.

In this case, you can save the git log output to a file and transfer that file to the test environment so that Launchable CLI can see the changes under test.

In the build machine, you will need to run a git log command with --pretty='format:{"commit": "%H", "parents": "%P", "authorEmail": "%ae", "authorTime": "%aI", "committerEmail": "%ce", "committerTime": "%cI"}' --numstat. You need to limit the number of commits to be written out. You can use --max-count option. Typically 10 to 20 commits should be suffice. Advanced users can tweak the ranges as needed to limit the amount of data.

# Check out the repository and build artifacts
git clone https://git.internal.example.com/repo
cd repo
make all


# Save git log data to a file. Using --max-count to limit the number of commits.
git log --pretty='format:{"commit": "%H", "parents": "%P", "authorEmail": "%ae", "authorTime": "%aI", "committerEmail": "%ce", "committerTime": "%cI"}' --numstat  --max-count 10 > git_log_output
# Save the current commit hash
git rev-parse HEAD > git_commit_hash


# Save the artifacts and git outputs
scp server_test_bin git_log_output git_commit_hash fileserver.internal.example.com:

The git log output (git_log_output file above) should contain the content like below:

{"commit": "1f0c18ea3df6575b4132b311d52a339af34c90ba", "parents": "b068a8a515e6cbbb2d6673ddb2c421939bd618b7", "authorEmail": "example1@example.com", "authorTime": "2022-09-21T15:59:21-07:00", "committerEmail": "example1@example.com", "committerTime": "2022-09-21T16:34:35-07:00"}
24	4	main.cc
24	0	main_test.cc


{"commit": "b068a8a515e6cbbb2d6673ddb2c421939bd618b7", "parents": "cb1d1b797726fe16e661d8377bd807f2508e9df4", "authorEmail": "example2@example.com", "authorTime": "2022-09-16T17:03:52+00:00", "committerEmail": "example3@example.com", "committerTime": "2022-09-16T17:03:52+00:00"}
1	1	docs/README.md

In the test machine, you will need to use these files to upload the commit data.

scp -R fileserver.internal.example.com: .


# Record commits and build
BUILD_NAME=build-$(cat git_commit_hash)
launchable record commit --import-git-log-output git_log_output
launchable record build --no-commit-collection --commit .=$(cat git_commit_hash) --name $BUILD_NAME
launchable record session --name $BUILD_NAME


# Run tests
./server_test_bin
