Quick Deploy vm ESXi mat Terraform

Hallo jiddereen, mäin Numm ass Ivan an ech sinn en alkoholescht System Administrateur (OPS).

Ech wéilt Iech soen wéi ech virtuell Maschinnen op ESXi ouni vCenter benotzt Terraform ofsetzen.

Zimlech dacks musst Dir virtuell Maschinnen ofsetzen / nei kreéieren fir dës oder déi Applikatioun ze testen. Wéinst der Faulegkeet hunn ech geduecht fir de Prozess ze automatiséieren. Meng Sich huet mech zu engem wonnerbare Produkt vun der Firma gefouert hashicorp, Terraform.

Ech denken, datt vill Leit wëssen wat Terraform ass, a wien et net weess, dëst ass eng Applikatioun fir all Cloud, Infrastruktur oder Service mat dem IasC Konzept ze managen (Infrastruktur als Code).

Ech benotzen ESXi als meng virtualization Ëmwelt. Ganz einfach, praktesch an zouverlässeg.
Ech erwaarden eng Fro.

Firwat terraform wann Dir vCenter Server benotzen kann?

Dir kënnt natierlech, mä. Als éischt ass dëst eng zousätzlech Lizenz, zweetens ass dëst Produkt ganz ressourceintensiv a passt einfach net op mengem Heemserver, an drëttens d'Fäegkeet fir d'Fäegkeeten ze upgrade.

D'Intel NUC Plattform funktionnéiert als Server:

CPU: 2 CPUs x Intel(R) Core(TM) i3-4010U CPU @ 1.70GHz
RAM: 8Gb
HDD: 500Gb
ESXi version: ESXi-6.5.0-4564106-standard (VMware, Inc.)

An also, éischt Saachen éischt.

Fir elo, loosst eis esxi opsetzen, nämlech de VNC Hafen an de Firewall Astellungen opmaachen.

Par défaut ass d'Datei schrëftlech geschützt. Mir maachen déi folgend Manipulatiounen:

chmod 644 /etc/vmware/firewall/service.xml
chmod +t /etc/vmware/firewall/service.xml
vi /etc/vmware/firewall/service.xml

fügen de folgende Block um Enn vun der Datei un:

<service id="1000">
  <id>packer-vnc</id>
  <rule id="0000">
    <direction>inbound</direction>
    <protocol>tcp</protocol>
    <porttype>dst</porttype>
    <port>
      <begin>5900</begin>
      <end>6000</end>
    </port>
  </rule>
  <enabled>true</enabled>
  <required>true</required>
</service>

Sortie, späicheren. Ännert d'Rechter zréck an de Service nei starten:

chmod 444 /etc/vmware/firewall/service.xml
esxcli network firewall refresh

Tatsächlech bis de Host nei gestart gëtt. Duerno muss dës Manipulatioun widderholl ginn.

Weider wäert ech all d'Aarbecht an enger virtueller Maschinn um selwechte Server ausféieren.

Produkter Spezifikatiounen:

OS: Centos 7 x86_64 minimal
RAM: 1GB
HDD: 20GB
Selinux: disable
firewalld: disable

Als nächst brauche mir Packer, och e Produkt vun HashiCorp.

Et ass néideg fir automatesch de "gëllene" Bild ze sammelen. déi mir an Zukunft wäerten benotzen.

yum install unzip git -y
curl -O https://releases.hashicorp.com/packer/1.5.5/packer_1.5.5_linux_amd64.zip
unzip packer_1.5.5_linux_amd64.zip -d /usr/bin && rm -rf packer_1.5.5_linux_amd64.zip
packer version
Packer v1.5.5

Ënnerwee Packer Versioun e Feeler kann optrieden, well RedHat-baséiert kann e Package mam selwechten Numm enthalen.

which -a packer
/usr/sbin/packer

Fir d'Léisung kënnt Dir e Symlink erstellen oder en absolute Wee benotzen /usr/bin/packer.

Elo brauche mir ovftool download Link. Eroflueden, setzen op de Server an installéieren:

chmod +x VMware-ovftool-4.4.0-15722219-lin.x86_64.bundle
./VMware-ovftool-4.4.0-15722219-lin.x86_64.bundle

Installation was successful.

Mir fuere weider.

Op der Gith hunn ech alles virbereet wat Dir braucht. 

git clone https://github.com/letnab/create-and-deploy-esxi.git && cd create-and-deploy-esxi

An den Dossier grouss Dir musst de Verdeelungskit vum Betribssystem setzen. A mengem Fall ass dëst Centos 7.

Dir musst och d'Datei änneren. centos-7-base.json:

variables: указать свои данные для подключения
iso_urls: указать актуальный
iso_checksum: чексумма вашего образа

No all Ännerungen, lafen d'Versammlung:

/usr/bin/packer build centos-7-base.json

Wann alles richteg konfiguréiert a spezifizéiert ass, gesitt Dir e Bild vun der automatescher Installatioun vum Betribssystem. Dëse Prozess dauert mech 7-8 Minutten.

Nom erfollegräichen Ofschloss am Dossier output-packer-centos7-x86_64 ova Datei gëtt lokaliséiert.

Terraform installéieren:

curl -O https://releases.hashicorp.com/terraform/0.12.24/terraform_0.12.24_linux_amd64.zip
unzip terraform_0.12.24_linux_amd64.zip -d /usr/bin/ && rm -rf terraform_0.12.24_linux_amd64.zip
terraform version
Terraform v0.12.24

Zanter Terraform hunn net Provider fir ESXi, Dir musst eng bauen.

Mir setzen op:

cd /tmp
curl -O https://dl.google.com/go/go1.14.2.linux-amd64.tar.gz
tar -C /usr/local -xzf go1.14.2.linux-amd64.tar.gz && rm -rf go1.14.2.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin
go version
go version go1.14.2 linux/amd64

Als nächst sammele mir de Provider:

go get -u -v golang.org/x/crypto/ssh
go get -u -v github.com/hashicorp/terraform
go get -u -v github.com/josenk/terraform-provider-esxi
export GOPATH="$HOME/go"
cd $GOPATH/src/github.com/josenk/terraform-provider-esxi
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -a -ldflags '-w -extldflags "-static"' -o terraform-provider-esxi_`cat version`
cp terraform-provider-esxi_`cat version` /usr/bin

Mir sinn op der Arrivée. Loosst eis eist Bild ausrollen.

Loosst eis an den Dossier goen:

cd /root/create-and-deploy-esxi/centos7

Als éischt ännert d'Datei variabelen.tf. Dir musst eng Verbindung zu der ESXi Server uginn.

Am Dossier network_config.cfg enthalen d'Netz Astellunge vun der zukünfteg virtueller Maschinn. Ännert op Är Bedierfnesser a lafen den One-Liner:

sed -i -e '2d' -e '3i "network": "'$(gzip < network_config.cfg| base64 | tr -d 'n')'",' metadata.json

Gutt, am Dossier main.tf änneren de Wee op d'ova Datei op Är eegen, wann anescht.

De Moment vun der Wourecht.

terraform init
Initializing the backend...

Initializing provider plugins...

The following providers do not have any version constraints in configuration,
so the latest version was installed.

To prevent automatic upgrades to new major versions that may contain breaking
changes, it is recommended to add version = "..." constraints to the
corresponding provider blocks in configuration, with the constraint strings
suggested below.

* provider.esxi: version = "~> 1.6"
* provider.template: version = "~> 2.1"

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

terraform plan
Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.

data.template_file.Default: Refreshing state...
data.template_file.network_config: Refreshing state...

------------------------------------------------------------------------

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # esxi_guest.Default will be created
  + resource "esxi_guest" "Default" {
      + boot_disk_size         = (known after apply)
      + disk_store             = "datastore1"
      + guest_name             = "centos7-test"
      + guest_shutdown_timeout = (known after apply)
      + guest_startup_timeout  = (known after apply)
      + guestinfo              = {
          + "metadata"          = "base64text"
          + "metadata.encoding" = "gzip+base64"
          + "userdata"          = "base64text"
          + "userdata.encoding" = "gzip+base64"
        }
      + guestos                = (known after apply)
      + id                     = (known after apply)
      + ip_address             = (known after apply)
      + memsize                = "1024"
      + notes                  = (known after apply)
      + numvcpus               = (known after apply)
      + ovf_properties_timer   = (known after apply)
      + ovf_source             = "/root/create-and-deploy-esxi/output-packer-centos7-x86_64/packer-centos7-x86_64.ova"
      + power                  = "on"
      + resource_pool_name     = (known after apply)
      + virthwver              = (known after apply)

      + network_interfaces {
          + mac_address     = (known after apply)
          + nic_type        = (known after apply)
          + virtual_network = "VM Network"
        }
    }

Plan: 1 to add, 0 to change, 0 to destroy.

------------------------------------------------------------------------

Note: You didn't specify an "-out" parameter to save this plan, so Terraform
can't guarantee that exactly these actions will be performed if
"terraform apply" is subsequently run.

Ofschloss:

terraform apply

Wann alles richteg gemaach gëtt, da gëtt an 2-3 Minutten eng nei virtuell Maschinn aus dem virdru gemaachten Bild ofgesat.

D'Benotzunge fir all dëst sinn nëmme vun Ärer Fantasi limitéiert.

Ech wollt just déi bescht Praktiken deelen an d'Haaptpunkte weisen wann Dir mat dëse Produkter schafft.

Merci fir d'Opmierksamkeet!

PS: Ech wäert frou sinn op konstruktiv Kritik.
