Deplwaman rapid nan vm ESXi lè l sèvi avèk Terraform

Bonjou tout moun, non mwen se Ivan e mwen se yon administratè sistèm alkòl (OPS).

Mwen ta renmen di w kouman mwen deplwaye machin vityèl sou ESXi san vCenter itilize Terraform.

Byen souvan ou oblije deplwaye/rekreye machin vityèl yo nan lòd yo teste aplikasyon sa a oswa sa a. Akòz parès, mwen te panse sou otomatize pwosesis la. Rechèch mwen an mennen m 'nan yon bèl pwodwi nan konpayi an hashicorp, terraform.

Mwen panse ke anpil moun konnen ki sa Terraform ye, men moun ki pa konnen, li se yon aplikasyon pou jere nenpòt nwaj, enfrastrikti oswa sèvis lè l sèvi avèk konsèp la IasC (Enfrastrikti kòm kòd).

Mwen sèvi ak ESXi kòm anviwònman Virtualization mwen an. Byen senp, pratik ak serye.
Mwen prevwa yon kesyon.

Poukisa terraform si ou ka itilize vCenter Server?

Natirèlman ou kapab, men... Premyèman, sa a se yon lisans adisyonèl, dezyèmman, pwodwi sa a se anpil resous-entansif epi tou senpleman pa pral anfòm sou sèvè lakay mwen, ak twazyèmman, li se yon opòtinite amelyore konpetans ou.

Platfòm Intel NUC aji kòm yon sèvè:

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.)

Se konsa, premye bagay an premye.

Pou kounye a, se pou yo konfigirasyon esxi, sètadi, louvri pò a VNC nan paramèt firewall yo.

Pa default, dosye a pwoteje ekri. Nou fè manipilasyon sa yo:

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

ajoute blòk sa a nan fen dosye a:

<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>

Nou sòti epi sove. Chanje dwa yo tounen epi rekòmanse sèvis la:

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

Valab jiskaske lame a rdemare. Apre sa, manipilasyon sa a pral oblije repete.

Depi koulye a mwen pral fè tout travay la nan yon machin vityèl sou sèvè a menm.

Pwodwi espesifikasyon:

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

Next nou bezwen pakè, tou yon pwodwi nan HashiCorp.

Li nesesè otomatikman rasanble imaj la "an lò". Ki nou pral itilize nan tan kap vini an.

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

Nan mouvman an vèsyon packer Yon erè ka rive paske ki baze sou RedHat ka genyen yon pake ki gen menm non an.

which -a packer
/usr/sbin/packer

Pou rezoud sa a, ou ka kreye yon lyen senbolik oswa itilize yon chemen absoli /usr/bin/packer.

Koulye a, nou bezwen ovftool download lyen. Telechaje, mete sou sèvè a epi enstale:

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.

Ann avanse.

Mwen te prepare tout sa mwen te bezwen pou gig la.

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

Nan katab ISO ou bezwen enstale distribisyon sistèm operasyon an. Nan ka mwen an li se centos 7.

Ou bezwen tou edite fichye a centos-7-base.json:

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

Apre tout chanjman yo, kouri bati a:

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

Si tout bagay se configuré ak espesifye kòrèkteman, Lè sa a, ou pral wè yon foto nan enstalasyon an otomatik nan sistèm nan fonksyone. Pwosesis sa a pran m '7-8 minit.

Apre yo fin konplete avèk siksè nan katab la pwodiksyon-packer-centos7-x86_64 pral gen yon dosye ova.

Enstale Terraform:

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

Depi Terraform pa gen yon founisè pou ESXi, ou bezwen bati youn.

Mete ale:

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

Apre sa, nou kolekte founisè a:

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

Nou nan liy fini an. Ann al woule imaj nou an.

Ale nan katab la:

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

Premye a tout, modifye dosye a varyab.tf. Ou bezwen presize yon koneksyon ak sèvè ESXi a.

Nan dosye network_config.cfg gen anviwònman rezo machin vityèl lavni an. Nou chanje li selon bezwen nou yo epi kouri yon sèl-revètisman an:

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

Oke, nan dosye a prensipal.tf chanje chemen an nan dosye ova a nan pwòp ou a, si diferan.

Moman verite a.

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.

Fini:

terraform apply

Si tout bagay fèt kòrèkteman, Lè sa a, nan 2-3 minit yon nouvo machin vityèl pral deplwaye soti nan imaj la te deja kreye.

Opsyon yo pou itilize tout bagay sa yo limite sèlman pa imajinasyon ou.

Mwen jis te vle pataje eksperyans mwen epi montre pwen prensipal yo lè w ap travay ak pwodwi sa yo.

Mèsi pou atansyon!

PS: Mwen pral kontan resevwa kritik konstriktif.
