Currently, Atlantis supports the following commands.

# atlantis help

atlantis help

# Explanation

View help

# atlantis version

atlantis version

# Explanation

Print the output of 'terraform version'.

# atlantis plan

atlantis plan [options] -- [terraform plan flags]

# Explanation

Runs terraform plan on the pull request's branch. You may wish to re-run plan after Atlantis has already done so if you've changed some resources manually.

# Examples

# Runs plan for any projects that Atlantis thinks were modified.
# If an `atlantis.yaml` file is specified, runs plan on the projects that
# were modified as determined by the `when_modified` config.
atlantis plan

# Runs plan in the root directory of the repo with workspace `default`.
atlantis plan -d .

# Runs plan in the `project1` directory of the repo with workspace `default`
atlantis plan -d project1

# Runs plan in the root directory of the repo with workspace `staging`
atlantis plan -w staging

# Options

• -d directory Which directory to run plan in relative to root of repo. Use . for root.
  • Ex. atlantis plan -d child/dir
• -p project Which project to run plan for. Refers to the name of the project configured in the repo's atlantis.yaml file. Cannot be used at same time as -d or -w because the project defines this already.
• -w workspace Switch to this Terraform workspace before planning. Defaults to default. If not using Terraform workspaces you can ignore this.
• --verbose Append Atlantis log to comment.

# Additional Terraform flags

If you need to run terraform plan with additional arguments, like -target=resource or -var 'foo-bar' or -var-file myfile.tfvars you can append them to the end of the comment after --, ex.

atlantis plan -d dir -- -var foo='bar'

If you always need to append a certain flag, see Custom Workflow Use Cases.

# atlantis apply

atlantis apply [options] -- [terraform apply flags]

# Explanation

Runs terraform apply for the plan that matches the directory/project/workspace.

# Examples

# Runs apply for all unapplied plans from this pull request.
atlantis apply

# Runs apply in the root directory of the repo with workspace `default`.
atlantis apply -d .

# Runs apply in the `project1` directory of the repo with workspace `default`
atlantis apply -d project1

# Runs apply in the root directory of the repo with workspace `staging`
atlantis apply -w staging

# Options

• -d directory Apply the plan for this directory, relative to root of repo. Use . for root.
• -p project Apply the plan for this project. Refers to the name of the project configured in the repo's atlantis.yaml file. Cannot be used at same time as -d or -w.
• -w workspace Apply the plan for this Terraform workspace. If not using Terraform workspaces you can ignore this.
• --auto-merge-disabled Disable automerge for this apply command.
• --verbose Append Atlantis log to comment.

# Additional Terraform flags

Because Atlantis under the hood is running terraform apply plan.tfplan, any Terraform options that would change the plan are ignored, ex:

• -target=resource
• -var 'foo=bar'
• -var-file=myfile.tfvars

They're ignored because they can't be specified for an already generated planfile. If you would like to specify these flags, do it while running atlantis plan.
