Google Cloud SDK

`gcloud` CLI

To learn more, visit:

The official documentation for the Google Cloud SDK
The gcloud cheatsheet

I'd also suggest you generate a local copy of the documentation offline.

Getting Started

Install the Google Cloud SDK

curl https://sdk.cloud.google.com | bash

Update the components
```
gcloud components update
```

Projects

Create a new project PROJECT_ID, setting it as the default for gcloud:

gcloud projects create PROJECT_ID \
  [--name PROJECT_NAME] \
  --set-as-default

Set your default project to existing project PROJECT_ID
```
gcloud config set project PROJECT_ID
```
Delete the project
```
gcloud projects delete 'my-project'
```
Undelete a project
```
gcloud projects undelete 'my-project'
```
Set example as the default project
```
gcloud projects set project 'example'
```

Authenticating

If you don't have an existing account, create one
```
gcloud init
```
Set an existing account to be the current active account
```
gcloud config set account 'ttrojan@usc.edu'
```
Generate credentials for the client libraries (such as Python)
```
gcloud auth application-default login
```
Generate credentials for the bq command-line interface
```
gcloud auth login --no-launch-browser
```

List the name of the active account

gcloud auth list --filter=status:ACTIVE --format="value(account)"

List the name of all inactive accounts starting with tmp

gcloud auth list --filter="-status:ACTIVE account:test*" \
--format="value(account)"

Cloud DNS

Useful tutorial

Describe the project information for project_id

gcloud dns project-info describe 'project_id'

Create a managed zone

gcloud dns managed-zones create --dns-name='helpful.wiki' --description='Helpful Wiki managed zone' 'helpfulwiki'

Enable DNSSEC

gcloud dns managed-zones update 'helpfulwiki' --dnssec-state on

Add an A name records to your domain

# Preset the variables
project="project-id"
zone="zone-id"
domain="website.com"

# Begin a transaction
gcloud dns --project=${project} \
  record-sets transaction \
  start \
  --zone=${zone}

# Add the IPs to a new A name record with a 1-hour TTL
gcloud dns --project=${project} \
  record-sets transaction \
  add '1.2.3.4' '2.3.4.5' --name="${domain}." --ttl=3600 --type='A' 
  --zone=${zone}

# Execute the transation
gcloud dns --project=${project} \
  record-sets transaction \
  execute \
  --zone=${zone}

SSL

Create a certificate for helpful.wiki, and name it certificate

gcloud compute ssl-certificates create 'certificate' --domains='helpful.wiki' --global

Cloud SQL

Google's article Creating and managing MySQL databases covers this material pretty well, I've included some commands below

Note, the --async flag returns immediately, without waiting for the operation to complete

Creating an instance

instance_name='my_instance'
tier='db-f1-micro'
region='us-west1'
version='MYSQL_8_0'

gcloud sql instances create ${instance_name} --tier=${tier} region=${region} --database-version=${version}

Deleting an instance

instance_name='my_instance'

gcloud sql instances delete ${instance_name} --async

Creating a database

instance_name='my_instance'
database_name='my_database'

gcloud sql databases create ${database_name} --instance=${instance_name} --async

Deleting a database

instance_name='my_instance'
database_name='my_database'

gcloud sql databases delete ${database_name} --instance=${instance_name} --async

Exporting SQL data

bucket='gs://helpfulwiki'
instance_name='my_instance'
database_name='my_database'
gcloud sql export sql ${instance_name} "${bucket}/sqldata.gz" --database=${database}

Be sure to follow best practices for importing and exporting

I'd also take a look at Google's article about creating and managing MySQL users. If you see references to % as the host, it denotes an unrestricted host name. They wrote a good post on MySQL users as well.

Assigning a password to the root user

gcloud sql users set-password 'root' --password='root' --instance='my_instance' --host='%'

Changing the password of a regular user

gcloud sql users set-password 'username' --instance='my_instance' --host='1.2.3.4' --prompt-for-password

Enabling access via a public IP

gcloud sql instances patch 'my_instance' --assign-ip

Configuring which public IPs can access the instance

gcloud sql instances patch 'my_instance' --authorized-networks='1.2.3.4, 5.6.7.8'

Creating a user

gcloud sql users create 'username' --host='1.2.3.4' --instance='my_instance' --prompt-for-password

Listing existing users

gcloud sql users list --instance='my_instance'

Deleting a user

gcloud sql users delete atraver --host='1.2.3.4' --instance='my_instance'

Configure a user's access
- Google's article about MySQL users

Check out Google's article about connecting with MySQL Workbench, as well as their article about exporting data to a SQL dump file in Cloud Storage

Export contents of database mydatabase Cloud SQL instance myinstance to Cloud Storage bucket gs://mybucket

First, enable WRITE access for the Cloud SQL instance's service account:

gcloud sql instances describe 'myinstance' | grep 'serviceAccountEmailAddress'
# => p11111-hp11gs@gcp-sa-cloud-sql.iam.gserviceaccount.com
service_account='p11111-hp11gs@gcp-sa-cloud-sql.iam.gserviceaccount.com'

gsutil acl ch -u "${service_account}:W" gs://mybucket

Next, export the data

gcloud sql export sql 'myinstance' gs://mybucket/sqldump.gz --database='mydatabase'

Google wrote a great article about starting, stopping, and restarting instances

Starting an instance

gcloud sql instances patch 'myinstance' --activation-policy 'ALWAYS'

Stopping an instance

gcloud sql instances patch 'myinstance' --activation-policy 'NEVER'

Restarting an instance

gcloud sql instances restart 'myinstance'

Opening up port 445 (SMB protocol) to all addresses

gcloud compute firewall-rules create RULE_NAME \
    --priority 1000 \
    --allow 'tcp:445' \
    --source-ranges '0.0.0.0/0'

Cloud VPN

I'm still exploring this topic, but I found Stephanie Wong's video tutorials to be helpful in gaining more solid footing on cloud networking fundamentals.
