In a series of posts, I will give a brief introduction on how to host an application on Knative, which is an open source framework of FaaS. If you haven't heard of Knative, maybe you have probably heard AWS Lambda, which is a FaaS product managed by AWS.
First, install envsubst, which is installed by the gettext package. We will use envsubst in later chapters where we substitute parameters especially environment variables and things like that.
To install gettext on CentOS:
$ yum install gettext
MacOS:
$ brew install gettext

The Google Cloud SDK installer will now prompt you to update an rc
file to bring the Google Cloud CLIs into your environment.
Enter a path to an rc file to update, or leave blank to use
[/Users/leodu/.bash_profile]:
Backing up [/Users/leodu/.bash_profile] to [/Users/leodu/.bash_profile.backup].
[/Users/leodu/.bash_profile] has been updated.
==> Start a new shell for the changes to take effect.
For more information on how to get started, please visit:

Start a new shell for the changes to take effect.
Initialize the SDK. Below command works both on MacOS and Linux.
$ ./google-cloud-sdk/bin/gcloud init
Welcome! This command will take you through the configuration of gcloud.
Your current configuration has been set to: [default]
You can skip diagnostics next time by using the following flag:
gcloud init --skip-diagnostics
Network diagnostic detects and fixes local network connection issues.
Checking network connection...done.
Reachability Check passed.
Network diagnostic passed (1/1 checks passed).
You must log in to continue. Would you like to log in (Y/n)? y
Your browser has been opened to visit:
https://accounts.google.com/o/oauth2/auth?###
You are logged in as: [li###u@tianzhui.cloud].
Pick cloud project to use:
[1] ###
...
[12] Create a new project
Please enter numeric choice or text value (must exactly match list
item): 2
Your current project has been set to: [###].
Not setting default zone/region (this feature makes it easier to use
[gcloud compute] by setting an appropriate default value for the
--zone and --region flag).
See https://cloud.google.com/compute/docs/gcloud-compute section on how to set
default compute region and zone manually. If you would like [gcloud init] to be
able to do this for you the next time you run it, make sure the
Compute Engine API is enabled for your project on the
https://console.developers.google.com/apis page.
Created a default .boto configuration file at [/Users/leodu/.boto]. See this file and
[https://cloud.google.com/storage/docs/gsutil/commands/config] for more
information about configuring Google Cloud Storage.
Your Google Cloud SDK is configured and ready to use!
* Commands that require authentication will use liusongdu@tianzhui.cloud by default
* Commands will reference project `###` by default
Run `gcloud help config` to learn how to change individual settings
This gcloud configuration is called [default]. You can create additional configurations if you work with multiple accounts and/or projects.
Run `gcloud topic configurations` to learn more.
Some things to try next:
* Run `gcloud --help` to see the Cloud Platform services you can interact with. And run `gcloud help COMMAND` to get help on any gcloud command.
* Run `gcloud topic --help` to learn about advanced features of the SDK like arg files and output formatting
When executing below docker build command, make sure it could communicate with gcloud API endpoints. Otherwise maybe see below error.
ERROR: gcloud crashed (TransportError): ('Connection aborted.', ConnectionResetError(54, 'Connection reset by peer'))
If you would like to report this issue, please run the following command:
gcloud feedback
To check gcloud for common problems, please run the following command:
gcloud info --run-diagnostics
Authentication methods
Configure Container Registry credentials for use with Docker directly in gcloud.
Use the gcloud tool to configure authentication. Log in to gcloud as the user that will run Docker commands. Configure authentication with user credentials
$ ./google-cloud-sdk/bin/gcloud auth login
Go to the following link in your browser:
https://accounts.google.com/o/oauth2/auth?###
Enter verification code: 4***8
You are now logged in as [l###u@tianzhui.cloud].
Your current project is [###]. You can change this setting by running:
$ gcloud config set project PROJECT_ID
Configure Docker.
$ ./google-cloud-sdk/bin/gcloud auth configure-docker
WARNING: `docker-credential-gcloud` not in system PATH.
gcloud's Docker credential helper can be configured but it will not work until this is corrected.
Adding credentials for all GCR repositories.
WARNING: A long list of credential helpers may cause delays running 'docker build'. We recommend passing the registry name to configure only the registry you are using.
After update, the following will be written to your Docker config file
located at [/root/.docker/config.json]:
{
"credHelpers": {
"gcr.io": "gcloud",
"us.gcr.io": "gcloud",
"eu.gcr.io": "gcloud",
"asia.gcr.io": "gcloud",
"staging-k8s.gcr.io": "gcloud",
"marketplace.gcr.io": "gcloud"
}
}
Do you want to continue (Y/n)? y
Docker configuration file updated.
Docker is now configured to authenticate with Container Registry.# export PATH=$PATH:~/google-cloud-sdk/bin
