🥇Sebarkeun gancang vm ESXi sareng Terraform

Halo sadayana, nami abdi Ivan sareng abdi administrator sistem alkohol (OPS).

Abdi hoyong ngabejaan ka maneh kumaha kuring nyebarkeun mesin virtual on ESXi tanpa vCenter maké Terraform.

Cukup sering, anjeun kedah nyebarkeun / nyiptakeun mesin virtual pikeun nguji aplikasi ieu atanapi éta. Kusabab kedul, kuring mikir ngeunaan ngajadikeun otomatis prosésna. Pilarian kuring nyababkeun kuring ka produk perusahaan anu saé hashicorp, terraform.

Jigana seueur anu terang naon Terraform, sareng saha anu henteu terang, ieu mangrupikeun aplikasi pikeun ngatur awan, infrastruktur atanapi jasa nganggo konsép IasC (Infrastruktur salaku kode).

Kuring make ESXi salaku lingkungan virtualization kuring. Rada basajan, merenah tur dipercaya.
Kuring antisipasi patarosan.

Naha terraform nalika anjeun tiasa nganggo vCenter Server?

Anjeun tiasa tangtosna, tapi. Firstly, ieu téh hiji lisénsi tambahan, Bréh, produk ieu pisan sumberdaya-intensif jeung ngan saukur teu cocog dina server imah kuring, jeung katilu, kamampuhan pikeun ngaronjatkeun kaahlian.

Platform Intel NUC tindakan minangka 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.)

Jeung saterusna, hal kahiji kahiji.

Pikeun ayeuna, hayu urang nyetél esxi, nyaéta, buka port VNC dina setélan firewall.

Sacara standar, file ditangtayungan tulisan. Kami ngalaksanakeun manipulasi ieu:

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

tambahkeun blok di handap ieu ka tungtung file:

<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>

Kaluar, simpen. Robah hak deui sareng balikan deui jasa:

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

Sabenerna dugi host rebooted. Saatos éta, manipulasi ieu kedah diulang deui.

Salajengna, abdi bakal ngalaksanakeun sagala pagawean dina mesin virtual dina server sarua.

fitur:

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

Salajengna, urang peryogi packer, ogé produk HashiCorp.

Ieu diperlukeun pikeun otomatis ngumpul gambar "emas". nu bakal kami pake dina mangsa nu bakal datang.

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

Ngaléngkah Vérsi packer kasalahan bisa lumangsung, saprak basis RedHat bisa ngandung hiji pakét jeung ngaran anu sarua.

which -a packer
/usr/sbin/packer

Pikeun solusi, anjeun tiasa nyiptakeun symlink, atanapi nganggo jalur mutlak /usr/bin/packer.

Ayeuna urang kudu ovftool download link. Unduh, pasang dina server sareng pasang:

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

Urang ngaléngkah.

Dina gith I nyiapkeun sagalana nu peryogi.

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

Pikeun folder gede Anjeun kedah nempatkeun kit distribusi sistem operasi. Dina kasus kuring, ieu centos 7.

Anjeun ogé kedah ngédit file. centos-7-base.json:

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

Saatos sagala parobihan, jalankeun rakitan:

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

Lamun sagalana geus ngonpigurasi tur dieusian leres, anjeun bakal nempo gambar tina instalasi otomatis tina sistem operasi. Prosés ieu nyandak kuring 7-8 menit.

Saatos parantosan suksés dina polder kaluaran-packer-centos7-x86_64 file ova bakal ayana.

Pasang 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

Kusabab Terraform teu boga panyadia pikeun ESXi, anjeun kudu ngawangun hiji.

Urang nempatkeun:

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

Salajengna, urang ngumpulkeun panyadia:

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

Kami di garis finish. Hayu urang gulung kaluar gambar urang.

Hayu urang buka folder:

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

Anu mimiti, edit file variabel.tf. Anjeun kudu nangtukeun sambungan kana server ESXi.

Dina file network_config.cfg ngandung setélan jaringan tina mesin virtual hareup. Robah kana kabutuhan anjeun sareng jalankeun one-liner:

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

Muhun, dina file utama.tf ngarobah jalur ka file ova ka anjeun sorangan, lamun béda.

Momen bebeneran.

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.

rengse:

terraform apply

Lamun sagalana geus rengse neuleu, lajeng dina 2-3 menit mesin virtual anyar bakal deployed ti gambar saméméhna dijieun.

Mangpaat pikeun sakabéh ieu diwatesan ngan ku imajinasi anjeun.

Kuring ngan ukur hoyong bagikeun prakték anu pangsaéna sareng nunjukkeun titik-titik utama nalika damel sareng produk ieu.

Hatur nuhun kana perhatosan!

PS: Kuring bakal bungah pikeun kritik konstruktif.
