Terraform also allows you to easily modify any Object Storage deployment by just making changes to the configuration file. Terraform will figure out the differences between the existing and desired state and then deploy the changes to the live services.<\/p>\n\n\n\n

Note that not all configuration options can be changed without replacing the Object Storage instance. For example, storage size can only be increased to prevent data loss. Furthermore, changing the Object Storage name or location will require resources to be replaced.<\/p>\n\n\n\n

Warning<\/span>: operations that force replacement will cause all data in the Object Storage to be deleted.<\/p>\n\n\n\n

In the example configuration below, we\u2019ve increased the Object Storage size from 250 GB to 500 GB, updated the access and secret keys, changed the description and removed one of the buckets.<\/p>\n\n\n\n

resource \"upcloud_object_storage\" \"my_object_storage\" {\n  # Increasing storage size\n  size  = 500<\/span>\n\n  # The access and secret keys as well as the description can be updated\n  access_key = \"iejdyugafsefsfhw<\/span>\"\n  secret_key = \"wad1e2evgh3olhym<\/span>\"\n  description = \"hosting\"\n\n  # (unchanged attributes hidden)\n  # Buckets can be added and deleted\n  bucket {\n    name = \"images\"\n  }\n}<\/pre>\n\n\n\n
When you have made your changes to the configuration, use the plan and apply commands to update your Object Storage.<\/p>\n\n\n\n
terraform plan<\/pre>\n\n\n\n
terraform apply<\/pre>\n\n\n\n
You\u2019ll then see an output similar to the example below.<\/p>\n\n\n\n
upcloud_object_storage.my_object_storage: Refreshing state... [id=06a6930f-d5ed-4e65-bdb6-28f73d562f12]<\/strong>\n\nTerraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:\n  ~ update in-place\n\nTerraform will perform the following actions:\n\n  # upcloud_object_storage.my_object_storage<\/strong> will be updated in-place\n  ~ resource \"upcloud_object_storage\" \"my_object_storage\" {\n      ~ access_key  = \"awodhouafsefrfhj\" -> \"iejdyugafsefsfhw\"\n      ~ description = \"catalogue\" -> \"hosting\"\n        id          = \"06a6930f-d5ed-4e65-bdb6-28f73d562f12\"\n      ~ name        = \"obj-terraform-raiou\" -> \"storage-name\"\n      ~ secret_key  = \"3piafn895a9fjpi5\" -> \"wad1e2evgh3olhym\"\n      ~ size        = 250 -> 500\n        # (5 unchanged attributes hidden)\n\n      - bucket {\n          - name = \"products\" -> null\n        }\n        # (1 unchanged block hidden)\n    }\n\nPlan:<\/strong> 0 to add, 1 to change, 0 to destroy.\nupcloud_object_storage.my_object_storage: Modifying...

Resources: 0 added, 1 changed, 0 destroyed.<\/strong><\/span><\/pre>\n\n\n\n
Afterwards, your Object Storage is up and running again with the new changes in place.<\/p>\n\n\n\n
Connecting to Object Storage using S3cmd<\/h2>\n\n\n\n
When you\u2019ve deployed your Object Storage using Terraform, you\u2019ll next probably want to connect to it. S3cmd is a simple yet powerful command-line tool for managing S3-compatible object storage and works great with UpCloud Object Storage.<\/p>\n\n\n\n
To make use of S3cmd, you\u2019ll need to install and configure it for your Object Storage instance.<\/p>\n\n\n\n
You\u2019ll need to install Python, download and install pip, and then install S3cmd using pip.<\/p>\n\n\n\n
# Ubuntu and Debian\nsudo apt-get install python3 python3-distutils -y\nwget https:\/\/bootstrap.pypa.io\/get-pip.py -O ~\/get-pip.py\nsudo python3 ~\/get-pip.py\nsudo pip install s3cmd<\/pre>\n\n\n\n
Next, get the required connection details from the Terraform state file using the following command.<\/p>\n\n\n\n
terraform show<\/pre>\n\n\n\n
# upcloud_object_storage.my_object_storage:\nresource \"upcloud_object_storage\" \"my_object_storage\" {\n    access_key  = \"iejdyugafsefsfhw\"<\/span>\n    created     = \"2021-06-14T15:10:31Z\"\n    description = \"hosting\"\n    id          = \"068ea905-7120-4927-b9ef-acf34243aa2e\"\n    name        = \"storage-name\"\n    secret_key  = \"wad1e2evgh3olhym\"<\/span>\n    size        = 500\n    state       = \"started\"\n    url         = \"https:\/\/storage-name.nl-ams1.upcloudobjects.com\/\"<\/span>\n    used_space  = 0\n    zone        = \"nl-ams1\"\n\n    bucket {\n        name = \"images\"\n    }\n}<\/pre>\n\n\n\n
Make note of your Object Storage\u2019s access_key<\/tt>, sercret_key<\/tt>, and the endpoint url<\/tt> which are needed to be able to connect using an S3 client.<\/p>\n\n\n\n
Next, use the command below to run the S3cmd configuration script.<\/p>\n\n\n\n
s3cmd --configure<\/pre>\n\n\n\n
Then enter the required details in the order they are asked. Set your keys and endpoint URL as shown in the output of the terraform show<\/tt> command. Also, set a password for file transfer encryption. Other fields can be skipped by simply pressing Enter<\/em> key to use the default value.<\/p>\n\n\n\n
Then at the end, confirm to save settings.<\/p>\n\n\n\n
Save settings? [y\/N] y\nConfiguration saved to '\/home\/user\/.s3cfg'<\/pre>\n\n\n\n
If you created a bucket in your Terraform configuration, you can confirm it by listing the buckets in your Object Storage.<\/p>\n\n\n\n
s3cmd ls<\/pre>\n\n\n\n
2021-06-16 16:34  s3:\/\/images<\/pre>\n\n\n\n
A response showing your buckets confirms you\u2019ve configured S3cmd correctly and are all set to start uploading files.<\/p>\n\n\n\n
