From a4236c375ddf78258a8f9252c1d79c665aa4f88b Mon Sep 17 00:00:00 2001 From: Lucendio Date: Mon, 25 Oct 2021 21:31:07 +0200 Subject: Add module 'write-files-deferred' executed in stage 'final' (#916) The main idea is to introduce a second module that takes care of writing files, but in the 'final' stage. While the introduction of a second module would allow for choosing the appropriate place withing the order of modules (and stages), there is no addition top-level directive being added to the cloud configuration schema. Instead, 'write-files' schema is being extended to include a 'defer' attribute used only by the 'write-deffered-files' modules. The new module 'write-deferred-files' reuses as much as possible of the 'write-files' functionality. --- tests/integration_tests/modules/test_write_files.py | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) (limited to 'tests/integration_tests') diff --git a/tests/integration_tests/modules/test_write_files.py b/tests/integration_tests/modules/test_write_files.py index 15832ae3..1d532fac 100644 --- a/tests/integration_tests/modules/test_write_files.py +++ b/tests/integration_tests/modules/test_write_files.py @@ -21,6 +21,9 @@ B64_CONTENT = base64.b64encode(ASCII_TEXT.encode("utf-8")) # USER_DATA = """\ #cloud-config +users: +- default +- name: myuser write_files: - encoding: b64 content: {} @@ -41,6 +44,12 @@ write_files: H4sIAIDb/U8C/1NW1E/KzNMvzuBKTc7IV8hIzcnJVyjPL8pJ4QIA6N+MVxsAAAA= path: /root/file_gzip permissions: '0755' +- path: '/home/testuser/my-file' + content: | + echo 'hello world!' + defer: true + owner: 'myuser' + permissions: '0644' """.format(B64_CONTENT.decode("ascii")) @@ -64,3 +73,15 @@ class TestWriteFiles: def test_write_files(self, cmd, expected_out, class_client): out = class_client.execute(cmd) assert expected_out in out + + def test_write_files_deferred(self, class_client): + """Test that write files deferred works as expected. + + Users get created after write_files module runs, so ensure that + with `defer: true`, the file gets written with correct ownership. + """ + out = class_client.read_from_file("/home/testuser/my-file") + assert "echo 'hello world!'" == out + assert class_client.execute( + 'stat -c "%U %a" /home/testuser/my-file' + ) == 'myuser 644' -- cgit v1.2.3
