How to Run an Ethereum (Geth Light) Node on GCP

How to Run an Ethereum Node in GCP

NOTE: This doc was created in 2018 and is no longer being kept up-to-date. There are some useful updates and Q&A in the comments, and Google has since disallowed cryptocurrency nodes explicitly in their Terms of Service. While I work on an updated how-to-run-a-node tutorial, you are welcome to join our ETH developer chat and share what you'd like to work on.

Example Go GitLab CI setup (no root/sudo required)
# See docs/examples
# http://doc.gitlab.com/ce/ci/quick_start/README.html
# http://doc.gitlab.com/ce/ci/yaml/README.html
# GitLab CI template for Go tests. Note this installs
# a new working copy of Go in a non-standard path such
# that sudo/root is not needed for the install stage.
# note that this particular install-environment stage
# is overly verbose in order to debug anything tricky
