```
gcloud config set project my-project
```

You may also set the environment variable `CLOUDSDK_CORE_PROJECT`.

### Change project default Compute Engine Region

```
gcloud config set compute/region NAME
```

### Change project default Compute Engine Zone

```
gcloud config set compute/zone NAME
```

### Env vars

```
CLOUDSDK_COMPUTE_REGION=us-central1
CLOUDSDK_COMPUTE_ZONE=us-central1-a
CLOUDSDK_CORE_PROJECT=my-project-123456
CLOUDSDK_CONTAINER_CLUSTER=cluster-1
```

### Show current project

```
gcloud config list --format 'value(core.project)'
```

### List config

```
gcloud config configurations list
```

## Compute

### SSH to VM

```
gcloud compute --project "proj-id-253611" ssh --zone us-central1-a instance-1
```

### Transfer files to VM

Delete VM

```bash
# Make sure you are using the correct account
gcloud config list

# Display instance info
gcloud compute instances describe instance-1 --zone=us-central1-a --project=proj-id-253611gcloud compute instances describe instance-1 --zone=us-central1-a --project=proj-id-253611

# Delete instanace and ALL DISKS
gcloud compute instances delete instance-1 --zone=us-central1-a --project=proj-id-253611 --delete-disks=all
```

## Kubernetes

### Get credentials

```bash
gcloud container clusters get-credentials cluster-1 --zone us-central1-c --project proj-id-253611
```

Deploy

```bash
git clone \
    https://github.com/GoogleCloudPlatform/kubernetes-engine-samples
    
cd \
    kubernetes-engine-samples/hello-app
    

docker build -t \
    gcr.io/united-blend-253611/hello-app:v1 \
    $PWD
    
gcloud docker -- push \
    gcr.io/united-blend-253611/hello-app:v1
    
kubectl create deployment \
    hello-app \
    --image=gcr.io/united-blend-253611/hello-app:v1
    
kubectl expose deployment \
    hello-app \
    --type="LoadBalancer" --port \
    8080
    
kubectl get service hello-app \
    --watch
```

## Mount file system over SSH

```bash
# Create SSH tunnel
gcloud compute ssh your-instance-name --project=your-project-name -- -NL 9022:127.0.0.1:22

# Mount remote folder locally
sshfs -odebug,sshfs_debug,loglevel=debug,ServerAliveInterval=30,IdentityFile=~/.ssh/google_compute_engine your-username@localhost:/remote/folder/path /local/folder/path -p 9022

# Mount local folder remotelly
sshfs -odebug,sshfs_debug,loglevel=debug,ServerAliveInterval=30,IdentityFile=~/.ssh/google_compute_engine /local/folder/path your-username@localhost:/remote/folder/path -p 9022
```

rsync

```bash
# Openn SSH tunnel
gcloud compute ssh your-instance --project=your-project -- -NL 9022:127.0.0.1:22

# Rsync from local to remote
rsync --progress --checksum -a -e "ssh -p 9022 -o IdentityFile=~/.ssh/google_compute_engine" /local/path your-user@localhost:/remote/path/
```
