<\/p>\nHet is alweer te lang geleden dat ik iets gepost heb. In die tijd regelmatig bezig geweest met het uitrollen van VM’s met behulp van Terraform. Dit o.a. op hypervisors als VMWare en Proxmox. Aangezien er een steeds verdere migratie bezig is van On-Premise naar cloud, ben ik ook maar in de magische wereld van Azure gedoken.
\nDe volgende stap is dus het uitrollen van VM’s in Azure.<\/p>\n
Waar je bij de on-prem omgevingen meestal gewoon een resource aanmaakt met disk, netwerk en compute zijn dat bij Azure allemaal losse resources. Om een uitrol te doen moet je dus het volgende plaatje in de gaten houden.<\/p>\n
<\/p>\n
Kortom, de resources die we nodig hebben zijn:<\/p>\n
Verder hebben we ook een image nodig, welke niet een aparte resource is en natuurlijk de terraform azurerm provider. Om gebruik te kunnen maken van de Azure omgeving moeten we in Azure een subscription hebben en een resource group. Eventueel kun je de resource group ook met behulp van Terraform maken, mara in dit voorbeeld is die er al. Om 1 en ander wat flexibeler te maken gebruik ik altijd een var.tf file om wat variabelen te defini\u00ebren.<\/p>\n
De inhoud van deze var.tf file is als volgt:<\/p>\n
variable \"subscription_id\" {\r\ndefault = \"4xxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx\"\r\ndescription = \"Azure Subscription ID\"\r\n}\r\n\r\nvariable \"resourcegroupname\" {\r\ndefault = \"myresourcegroup\"\r\ndescription = \"Location\"\r\n}\r\n\r\nvariable \"location\" {\r\ndefault = \"South Central US\"\r\ndescription = \"Location\"\r\n}\r\n\r\nvariable \"vmsize\" {\r\ndefault = \"standard_d2s_v3\"\r\ndescription = \"Size of vm\"\r\n}\r\n\r\nvariable \"offer\" {\r\ndefault = \"0001-com-ubuntu-server-focal\"\r\ndescription = \"Offer For Ubuntu =< 18.04 default should be UbuntuServer\"\r\n}\r\n\r\nvariable \"sku\" {\r\ndefault = \"20_04-lts\"\r\ndescription = \"SKU\"\r\n}\r\n\r\nvariable \"admin_username\" {\r\ndefault = \"ubuntu\"\r\ndescription = \"Username\"\r\n}\r\n\r\nvariable \"admin_password\" {\r\ndefault = \"Super-Secret2022\"\r\ndescription = \"Password\"\r\n}\r\n\r\nvariable \"hostname\" {\r\ndefault = \"ubuntu-svr1\"\r\ndescription = \"Hostname\"\r\n}<\/code><\/pre>\nDe variabelen kun je naar wens aanpassen.
\nVervolgens hebben we ook nog een main.tf. De inhoud daarvan is als volgt:<\/p>\n
