pulumi-oci-vm-stack

Spinning up a Ubuntu VM instance with Oracle Cloud's Always Free Tier.
As of writing this, they offers;

• Two x64 VMs with 1/8 OCPU and 1 GB memory each
• Up to four arm64 VMs with 8 cores and 24 GB of memory in total (splittable to 1~4 VMs)

TL;DR

• Make sure you have
  • ~/.oci/config and your key pair. See How to Generate an API Signing Key.
  • Pulumi curl -fsSL https://get.pulumi.com | sh or asdf plugin-add && asdf install pulumi latest && asdf global pulumi latest
  • Node.js >= v16

$ npm ci

$ pulumi login file://.
$  export PULUMI_CONFIG_PASSPHRASE=your-pass-phrase
$ pulumi stack init dev

$ pulumi config set sshPubKey "$(< /path/to/pub_key.rsa)"
$ pulumi up -y

# Have a fun! Sometime it takes several minutes to be ready.
$ ssh ubuntu@$(pulumi stack output instanceIp) -i ~/.ssh/your_key.rsa

# Clean up
$ pulumi destroy

Pulumi configs

• sshPubKey
  • Required.
  • The SSH Public key to be added to /home/ubuntu/.ssh/authorized_keys.
• ingressSecurityRules
  • The list of ingress security rules. If not specified, only SSH(22) is allowed.
  • You may want to edit Pulumi.<stack>.yaml manually.

  # For example:
  oci-vm-stack:ingressSecurityRules:
    - proto: TCP # "ALL" | "ICMP" | "TCP" | "UDP" | "ICMPv6"
      source: "0.0.0.0/0"
      description: http
      port: 80
    - proto: UDP
      source: "0.0.0.0/0"
      description: myapp
      portRange: [3000, 3020] # Open 3000-3020/udp

• instanceShape
  • The VM instance shape. VM.Standard.A1.Flex | VM.Standard.E2.1.Micro
  • Default: VM.Standard.A1.Flex
  • See also https://docs.oracle.com/en-us/iaas/Content/Compute/References/computeshapes.htm
• instanceOcpus
  • The number of OCPUs assigned to the instance.
  • Default: 2
• instanceMemoryInGbs
  • The amount of RAM assigned to the instance, in GiB.
  • Default: 8

# Use x64 VM
$ pulumi config set instanceShape VM.Standard.E2.1.Micro
$ pulumi config set instanceOcpus 1
$ pulumi config set instanceMemoryInGbs 1

# Use arm64 VM (8 OCPUs, 24 GiB RAM)
$ pulumi config set instanceShape VM.Standard.A1.Flex
$ pulumi config set instanceOcpus 8
$ pulumi config set instanceMemoryInGbs 24
